Answer:

The lighter frogs will be eaten and will not be able to reproduce offspring with the light green trait. Darker green frogs will be able to reproduce more dark green frogs. Eventually most/all frogs will be a darker green because they carry a trait that improves chances of survival.

Li-Fraumeni syndrome (LFS1) is a rare hereditary disorder that leads to a predisposition to cancer. This hereditary disorder is

Nimfa-mama [501]

Answer:

CHK2, p53, p21, cell cycle progression.

Explanation:

In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

Which of the following best explains how the light reactions of photosynthesis generate ATP?

frutty [35]

Answer:

B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.

Explanation:

Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.

Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated fro

sladkih [1.3K]

Answer:

Total ATP molecules produced = 94 molecules of ATP

Explanation:

Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.

Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.

The overall yield of ATP from the various enzymatic steps is shown below:

Acyl-CoA dehydrodenase = 6 FADH₂

β-Hydroxyacyl-CoA dehydrogenase = 6 NADH

Isocitrate dehydrogenase = 7 NADH

α-Ketoglutarate dehydrogenase = 7 NADH

Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)

Succinate dehydrogenase = 7 FADH₂

Malate dehydrogenase = 7 NADH

Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,

Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5

Total NADH molecules = 27 * 2.5 = 67.5

Total ATP molecules produced = 19.5 + 67.5 + 7 = 94

Total ATP molecules produced = 94 molecules of ATP
