Answer: C) A statement made by Henrietta Lacks’s husband to a magazine
Explanation:An excerpt from The Immortal Life of Henrietta Lacks
"Eventually I tracked down a few magazine articles about her from the seventies. Ebony quoted Henrietta’s husband saying, 'All I remember is that she had this disease, and right after she died they called me in the office wanting to get my permission to take a sample of some kind. I decided not to let them.'"
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.
Endangered is when group of species are at the edge of extinction.
Threatening is when group of species are at the risk of extinction in future.
