The molecule for further use in the citric acid cycle is NAD+.

In the absence of oxygen after glycolysis cells undergo fermentation without the citric acid cycle or oxidative phosphorylation. The citric acid cycle requires oxygen. This is because the electron transport chain requires an electron acceptor to regenerate her NAD, which is the role of oxygen.

Some of this is considered an aerobic pathway because the NADH and FADH2 produced must transfer electrons to the next pathway in the system using oxygen. Without oxygen, this transfer would not occur. Two carbon atoms from each acetyl group enter the citric acid cycle. Oxygen is the terminal electron acceptor of the mitochondrial electron transport chain and is therefore required for energy production via oxidative phosphorylation.

Chemical mutagens that mimic the naturally occurring bases are called Base analogs. Option C

Base analogs are a kind of mutagen that mimics the shape and size of natural nucleotide bases, allowing them to be incorporated into DNA replication. This incorporation can lead to base substitution mutations, resulting in genetic changes.

A base analog is a chemical that replaces one of the nucleotide bases in DNA and can substitute for the natural nucleotide during DNA replication. Base analogs are chemically similar to the standard nucleotide bases, allowing them to pair with the opposite base in the double helix.

The best-known base analog is 5-bromouracil, which pairs with guanine (G) in DNA replication, but also pairs with adenine (A) when it exists in its rare, unstable keto form. As a result, 5-bromouracil can cause a transition mutation when it replaces thymine (T) in DNA replication.

Base analogs are used to study DNA replication and repair mechanisms, as well as to develop cancer drugs that target rapidly dividing cells. They are also used in genetic engineering to introduce specific mutations into DNA sequences to study gene function. Option C

A substance's specific heat tells you how much heat is required to increase the temperature of 1 g of that substance by 1°C.

The equation that establishes a relationshop between heat and change in temperature is

q = m • c • ∆T, where

q - heat absorbed

c - the specific heat of the substance, in your case of water

ΔT - the change in temperature, defined as the difference between the final temperature and the initial temperature

so:

q = 1.00 g • 4.18 J/g×°C • (75.0 - 38.5)°C

q = 152,57 J

just apply this formula for all exercises

A. How many Joules of energy are required to raise 3.50kg of water from 38.5 to 75.0C ? (specific heat of water is 4.184J/g C)(1000g=1kg)

Answer:

q = 534,506 Joules

q = 534.506 KiloJoules

534.506 KiloJoules or 534,506 Joules energy required to raise 3.50kg of water from 38.5 to 75.0C

Sp. Heat is the heat required to increase the temperature of the 1 mass of a given substance by a  \(1^{0}\) C temperature.

The formula of specific heat Cp = \(\frac{q}{m (∆T)}\)

Where,

q = energy of substance (Joules / KiloJoules),

Cp = Specific heat capacity of the substance (J/Kg.C),

m = mass of the substance

∆T = Change in temp.

Explanation:

Given data from que: -

Mss of the water (m) = 3.50 Kg = 3.50 × 1000 gm = 3500 gm

specific heat capacity of water (Cp) = 4.184J/g C

Change in temp (∆T) = 75.0 - 38.5 = 36.5

now, put all above given data in formula

we get

Cp = \(\frac{q}{m (∆T)}\)

q = Cp ×m×∆T

q = 4.184×3500×36.5

q = 534,506 Joules

q = 534.506 KJ

The diffusion rate of carbon dioxide out of the shell can be calculated using Fick's first law of diffusion, which states that the diffusion rate is proportional to the diffusion coefficient, the surface area, and the concentration difference.

First, we need to calculate the surface area of the shell:

The diameter of the shell is given as 4.5 cm, so the radius is half of that, which is 2.25 cm.

The surface area of a sphere is given by the formula A = 4πr^2.

Plugging in the radius, we get A = 4π(2.25 cm)^2 = 63.59 cm^2.

Next, we need to calculate the concentration difference:

The carbon dioxide concentration inside the shell is given as 2.0 atm, while the concentration outside the shell is essentially zero. The concentration difference is therefore 2.0 atm - 0 atm = 2.0 atm.

Now we can calculate the diffusion rate using the formula diffusion rate = diffusion coefficient * surface area * concentration difference. Plugging in the given values, we get diffusion rate = (2.5×10^(-12) m^2/s) * (63.59 cm^2) * (2.0 atm) = 3.18×10^(-9) cm^3·atm/s.

To convert this to molecules per second, we need to use Avogadro's number, which is 6.022×10^23 molecules/mol. Since carbon dioxide has a molar mass of approximately 44 g/mol, we can convert the diffusion rate to molecules per second by multiplying it by Avogadro's number and dividing by the molar mass of carbon dioxide. The molar mass of carbon dioxide is 44 g/mol = 44000 mg/mol.

diffusion rate (in molecules/s) = (3.18×10^(-9) cm^3·atm/s) * (6.022×10^23 molecules/mol) / (44000 mg/mol) = 4.34×10^14 molecules/s.

So, the diffusion rate of carbon dioxide out of the shell is 4.34×10^14 molecules/s.

For Part B, we can use the diffusion rate from Part A to calculate the time it takes for the carbon dioxide pressure to decrease to 1.0 atm.

The initial pressure is 2.0 atm and the final pressure is 1.0 atm.

Since the rate is constant, we can use the formula time = (final pressure - initial pressure) / diffusion rate.

Plugging in the values, we get time = (1.0 atm - 2.0 atm) / (4.34×10^14 molecules/s) = -2.3×10^(-15) s.

To convert this to hours, we divide by 3600 s/hour and take the absolute value to get time = |(-2.3×10^(-15) s) / (3600 s/hour)| = 6.4×10^(-19) hours.

So, it will take approximately 6.4×10^(-19) hours for the carbon dioxide pressure to decrease to 1.0 atm, assuming a constant diffusion rate.

If lysine is in a pH 13 solution, the net charge on each lysine molecule is +1. So, the correct option is b.

Lysine is a critical amino acid with several important functions in the body. It's a critical building block for proteins, and it also plays a critical role in the formation of enzymes, hormones, and other molecules that help maintain optimal health. Lysine is used by the body to help absorb calcium, develop muscle tissue, and support the immune system.

The isoelectric point (pI) of lysine can be calculated as follows:

pI = (pKa of the closest pKa below the pH) + (pKa of the closest pKa above the pH) / 2pI = (2.2 + 9.0) / 2pI = 5.6

When the pH of the solution is higher than the pI, lysine is deprotonated.

Therefore, in a pH 13 solution, lysine would have a positive net charge on the side chain and a negative net charge on the carboxyl group. The side chain and amino group, on the other hand, would both be deprotonated, with a net charge of +1 on the amino group (+9.0-13) and a net charge of +1 on the side chain (+10.5-13), resulting in a net charge of +1 on each lysine molecule.

Considering the Boyle's law, if the volume increases to 50 L, the new pressure is 0.4 atm.

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: If the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Mathematically, Boyle's law states that if the amount of gas and the temperature remain constant, the product of the pressure and the volume always has the same value:

P× V= k

where

Considering an initial state 1 and a final state 2, it is fulfilled:

P₁× V₁= P₂× V₂

In this case, you know:

Replacing in Boyle's law:

2 atm× 10 L= P₂× 50 L

The freezing point o the solution = 273.714153 K

The boiling point of the solution= 373.1955328 K

Explanation

Given:

Mass of glucose = 5.00 g

Volume of water = 72.8 g

What to find:

The freezing point and the boiling point of the solution.

Step-by-step solution:

Note: (Freezing point of water = 273K, Kf for water =1.87K kg/mol, atomic weight C = 12, H = 1, O = 16).

The freezing point of the solution:

The molecular weight of glucose C6H12O6 = 6(12) + 12(1) + 6(16) = 180 g/mol

The number of moles of glucose = (Mass of glucose/Molecular weight) = 5.00 g/180.0 g/mol = 0.0278 moles

Mass of water = 72.8 g = 0.0728 kg

So molality of glucose = (Moles o glcsose/Volume of solution) = 0.0278 mol/0.0728 kg = 0.3819 mol/kg

The depression in the freezing point, ∆T = Kf x molality = 1.87 K kg/mol x 0.3819 mol/kg = 0.714153 K

Since the freezing point of water = 273 K

Therefore, the freezing point of the solution= 273 K + 0.714153 K = 273.714153K

The boiling point of the solution:

∆T = i x m x Kb

∆T = change in temperature i.e boiling point elevation

i = van't Hoff factor = 1 for glucose since it does not ionize or dissociate. It is a single particle.

m = molality = moles solut/kg solvent = 0.0278 mol/0.0728 kg = 0.3819 mol/kg

Kb = boiling poin constant = 0.512 K kg/mol

∆T = 1 x 0.3819 mol/kg x 0.512 K kg/mol

∆T = 0.1955328 K

Since the freezing point of water = 373 K

Therefore, the boiling point of the solution = 373 K + 0.1955328 K = 373.1955328 K
