how that food molecules and oxygen transfer energy to the cell to support life’s processes, including controlling body temperature, despite losing energy as heat.
Cellular respiration is the process in which the food molecule along with oxygen is broken which provides energy to the muscle and tissue.
Why molecule is transported to the cell?Cellular respiration is a chemical manner in which the bonds of meal molecules and oxygen molecules are broken and new compounds that can deliver strength to muscle tissue are shaped. Cell respiratory releases the electricity had to maintain frame temperature notwithstanding ongoing electricity switch to the surrounding environment.
During cellular respiration, the energy which is present in the food is converted into the king of energy that is used by the body's cells. In this process, glucose and oxygen are converted into carbon dioxide and water, and the whole energy is transferred to ATP. Chemical respiration is the process in which the organism combines oxygen and produces energy which is required for the body's cells.
So we can conclude that cellular respiration is the process in which the food molecule along with oxygen is broken which provides energy to the muscle and tissue.

The five components of scientific method are: observations, questions, hypothesis, methods and results. Following scientific method procedure not only ensures that experiment can be repeated by other researchers, but also that the results garnered can be accepted.
1. Define a Question to Investigate
As scientists conduct their research, they make observations and collect the data. The observations and data often lead them to ask why something is the way its
2.Make Predictions
Based on their research and observations, scientists will often come up with hypothesis. A hypothesis is possible answer to a question.
3. Gather Data
Evidence is needed to test prediction. There are several strategies for collecting evidence, or data. Scientists can gather their data by observing the natural world, performing an experiment in laboratory, or by running mode
4. Analyze the Data
Scientists organize their data in tables, graphs, or the diagrams. If possible they include relevant data from other sources
5. Draw Conclusions
Based on whether or not their prediction came true scientists can then decide whether evidence clearly supports or does not support hypothesis

biological catalysts that increase the rates of biochemical reactions are known as? a. substrates b. inhibitors c. enzymes d. binders e. trumanettes
The correct option of the given statement "Biological catalysts that increase the rates of biochemical reactions are known as" is enzymes.
Enzymes are proteins that accelerate the rates of biochemical reactions. They act as biological catalysts, increasing the reaction rate without affecting the chemical reaction's thermodynamics (the free energy change). It hastens the rate of a reaction by reducing the activation energy necessary for the reaction to occur.
Enzymes are highly specific, with each enzyme catalyzing only one reaction or a group of closely related reactions. Inhibitors are compounds that inhibit or slow down the enzyme's activity, while substrates are compounds that are transformed into products by enzymes. Binders and Trumanettes are not related to enzymes.

Green plants use energy from the Sun to change carbon dioxide and water into food and oxygen. What clue tells you that this process is a chemical change?
Answer:
Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar and oxygen gas.

If you could attach fluorescent marker tags to the enzyme that transfers the acetyl group from acetyl CoA to oxaloacetate, and then detect that fluorescence wit which part of a cell would you predict to observe the fluorescence? A. in the mitochondrial intermembrane space B. in the mitochondrial matrix C. embedded in the outer mitochondrial membrane D. embedded in the inner mitochondrial membrane E. in the cytoplasm
The transfer of the acetyl group from acetyl CoA to oxaloacetate occurs in the mitochondrial matrix during the process of the citric acid cycle, also known as the Krebs cycle. Option B is the correct answer.
The mitochondrial matrix is the space enclosed by the inner mitochondrial membrane, where many metabolic reactions take place. Since the enzyme responsible for this transfer is involved in the citric acid cycle, it is located within the mitochondrial matrix. By attaching fluorescent marker tags to this enzyme, the fluorescence would be observed in the mitochondrial matrix, indicating the presence and activity of the enzyme in that specific compartment of the cell.
Therefore, the fluorescence would be detected in the mitochondrial matrix (Option B).

The ability of hormones to communicate with specific tissues and organs is a result of the specificity of the hormone-receptor interaction and the regulation of hormone concentration and distribution in the bloodstream. Distribution of hormones in the bloodstream, which is regulated by the endocrine system
Hormones are chemical messengers that are released by endocrine glands into the bloodstream and transported to specific target tissues or organs in the body. Hormones interact with specific receptors on the surface or inside the cells of the target tissues, triggering a response that affects cellular function. The ability of hormones to communicate with specific tissues and organs is due to the specificity of the hormone-receptor interaction. Each hormone has a specific molecular structure that allows it to bind to only certain receptor proteins on the surface of target cells, this binding triggers a cascade of intracellular events that ultimately lead to a physiological response in the target tissue or organ.
