What are the products of light-dependent reactions? Why are they important in light-independent reactions?

Answers

The products of light-dependent reaction are ATP and NADPH. They are essentially required to fix carbon dioxide and make glucose in light-independent reactions.

Light-dependent reactions are those that use the direct sunlight energy to make usable forms of chemical energy i.e., ATP and NADPH. For this, a pigment called chlorophyll is essential that has the ability to the capture the sunlight.

Light-independent reactions are those that do not directly depend on the sunlight energy to complete their process. Instead they are dependent on the products of light reactions so that they can fix atmospheric carbon dioxide and make glucose for the plant. Calvin cycle is the main process of light-independent reaction.

What are the 3 hormones released during exercise?

Answers

Exercise induces the release of three hormones: adrenaline, endorphins, and cortisol.

Adrenaline is a stress hormone released by the adrenal glands in response to physical or psychological stressors that increases heart rate, glucose levels, breathing rate, muscle strength and cognitive function.

Endorphins are neurotransmitters triggered by strenuous activity that provide a sense of euphoria, helping to reduce pain perception and improve mood.

Finally, cortisol is a steroid hormone released as part of the body’s fight-or-flight response which helps raise blood sugar levels while also aiding in tissue repair following exercise or physical activity.

Thusly, these hormones play an important role in not only maintaining homeostasis during physical activity but also providing relaxation after exercise has concluded.

How many reducing ends are there in a molecule of glycogen that contains 10,000 glucose residues and branches every 10 residues. How many non reducing ends are there in this molecule? show work and explain.

Answers

A molecule of glycogen that contains 10,000 glucose residues and branches every 10 residues will have 1,000 reducing ends and 9,000 non-reducing ends.

Here's the breakdown:

There is one reducing end for each chain of glycogen. Since the molecule branches every 10 residues, there will be 1 reducing end for every 10 glucose residues. This means there are 10,000/10 = 1,000 chains of glycogen and therefore 1,000 reducing ends.Each branch point in glycogen is a non-reducing end. Since the molecule branches every 10 residues, there will be 1 branch point for every 10 glucose residues. This means there are 10,000/10 = 1,000 branch points, and therefore 1,000 non-reducing ends. However, the non-reducing end of the main chain also counts as a non-reducing end, so the total number of non-reducing ends is 1,000 + 1 = 9,001.

In this article, we’ll look in greater depth at what an enzyme is and how it catalyzes a particular chemical reaction.

Enzymes and activation energy

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Photosynthesis is the primary funtion of the leaves.
Explanation:
Photosynthesis is defined as the chemical process of converting light energy into chemical energy in a form of food or sugar. Leaves contain most of the chloroplasts in plants that are responsible in capturing light for photosynthesis to occur.
Leaves are naturally green to serve their purpose. This green color is caused by the reflection of the green portion of the visible light spectrum by the green coloring pigment, chlorophyll. Chlorophyll, that is contained in chloroplasts, captures certain wavelengths of light, as energy to initiate photosynthesis. As a result, we get food from plants.

A. It is less complex than a tissue


B. It is more complex than an organ system


C. It is less complex than a cell


D. It is more complex than a tissue

Answers

Answer:

C

Explanation:

The level of structural organization for the tongue is that it is more complex than a tissue. So the correct option is D.

What is a tongue?

In most vertebrates, the tongue is a muscular organ on the floor of the mouth that may move in a variety of ways. It is extended and specialised in grabbing insect prey in some animals (like frogs).

While cats and certain other animals use their tongues as tools for grooming and cleaning, some reptiles' tongues serve largely as sensory organs.

The tongue is an essential auxiliary organ in chewing and swallowing, helps mammals create negative pressure in the oral canal to permit sucking, is a key carrier of taste receptors, and helps humans speak.

The mammalian tongue is formed of a complex of striated, intertwined muscles, fat, and glands, all coated in mucosal surfaces. Humans often have their front tongue ends and margins in contact with their teeth, which facilitates communication and swallowing.

Therefore the correct option is D.

Once the flasks are set up as desired. How long will fermentation be allowed to take place AND how will you know that fermentation actually happened? In other words, what will change to visually show you the chemical reaction is happening

Answers

The fermentation process will be allowed to take place for a specific duration, typically determined by the experiment or desired outcome. The occurrence of fermentation can be visually observed through various changes such as the production of bubbles, the release of gas, or changes in color or texture of the substance being fermented.

The duration for which fermentation is allowed to take place can vary depending on the specific experiment or desired outcome. It is typically determined based on the time required for the fermentation process to reach its maximum efficiency or for specific products to be produced. Common fermentation processes, such as yeast fermentation for bread-making or alcoholic fermentation, may have predetermined timeframes.

To visually confirm that fermentation is happening, several changes can be observed. One of the most noticeable signs is the production of bubbles or the release of gas. This is a result of the metabolic activity of microorganisms, such as yeast or bacteria, that produce carbon dioxide as a byproduct during fermentation. The presence of bubbles indicates the release of gas and the ongoing chemical reaction. Additionally, changes in color, texture, or consistency of the substance being fermented can also provide visual cues of fermentation. These changes can vary depending on the specific fermentation process and the substances involved. Overall, the duration of fermentation and the visual changes observed serve as indicators of the occurrence and progress of the chemical reaction, providing evidence that fermentation has taken place.

THE INTERNET AND THE INTRANET SHORTEN TIME TO MARKET FOR NEW DRUGS The Federal Drug Administration (FDA) must be extremely careful in approving new drugs. However, the FDA is under public pressure to approve new drugs quickly, especially those for cancer and HIV. The problem is that to ensure qual- ity, the FDA requires companies to conduct extensive research and clinical testing. The development programs of such research and testing cover 300,000 to 500,000 pages of documentation for each new drug. The subsequent results and analyses are reported on 100,000 to 200,000 additional pages. These pages then are reviewed by the FDA prior to approval of a new drug. Manual processing of this informa- tion significantly slows the work of the FDA, so that the total approval process takes 6 to 10 years. A software program called Computer-Aided Drug Application Systems (by Research Data Corporation, New Jersey) offered a computerized solution. The software used a network-distributed document-processing system that enabled the pharmaceutical company to scan all related doc- uments into a database. The documents were indexed, and full-text search and retrieval software was attached to the system. Using keywords, corporate employees could search the database via their company's intranet. The database was also accessible, via the Internet, to FDA employees, who no longer had to spend hours looking for a specific piece of data. Information could be processed or printed at the user's desktop computer. These functions enabled the U.S. govern- ment to offer an electronic submission and online review process for approval of new drugs (fda.gov/cder). This system helped not only the FDA, but also the com panies' researchers, who suddenly had every piece of required information at their fingertips. Remote corporate and busi ness partners could also access the system. The overall result was that the time-to-market of a new drug could be reduced by up to a year. Each week saved translates into the saving of many lives and also yields up to $1 million profit. The sys- tem also reduced the time it took to patent a new drug. An interesting use of this technology is the case of ISIS Pharmaceuticals, Inc. (isispharm.com), which developed an extranet-based system similar to the one described here. The company uses CD-ROMs to submit reports to the FDA and opens its intranet to FDA personnel. This step alone could save 6 to 12 months from the average 15-month review time. Simply by submitting an FDA report electronically, the com- pany can save one month of review time. To cut time even further, SmithKline Beecham Corporation is using electronic publishing and hypertext links to enable FDA reviewers to quickly navigate its submissions.
