Answer:
C. 10 ATP molecules
Explanation:
In the citric acid cycle is a series of eight reactions steps in which a two-carbon molecule, acetyl-CoA, enters the cycle through citrate and two atoms of carbon are removed as two molecules of carbon dioxide.
The energy generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle is conserved in the production of three NADH molecules, one FADH₂ and one ATP molecule. Each NADH molecule transfers two electrons to oxygen in the electron transport chain, forming 2.5 ATP molecules each in the process. Similarly, an FADH2 molecules transfers two electrons to oxygen in the electron transport chain yielding 1.5 ATP molecules.
Total ATP molecules produced:
3 NADH + 1 FADH2 + 1 ATP = (2.5 × 3) + (1.5 × 1) + 1 ATP = 10 ATP molecules
Therefore, 10 ATP molecules are generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle.
Answer: Option A) sister chromatids
In mitosis, each chromosome is made up of sister chromatids that carry the same alleles.
Explanation:
During the fourth phase of mitosis (Anaphase) the sister chromatids part company and migrate to the opposite poles, each with the same alleles since no crossing over occurred.
Thus, mitosis results in two daughter cells that have the same chromosome make-up as the original parent cell.
Answer:
To put it simply, the amount of radiation from one adult chest x-ray (0.1 mSv) is about the same as 10 days of natural background radiation that we are all exposed to as part of our daily living.
