Question

Use the following four answers for the next four questions

A) Gives 2 pyruvate, 2 NADH and 2 ATP without using oxygen

B) The part of oxidative phosphorylation where oxygen is converted to water

C) oxidization of carbons from Acetyl-CoA to CO₂, captures energy in the form of ATP and NADH

D) produces oxygen and hydrogen gas by removing electrons from water

) Which of the above describes photosystem II

) Which of the above does glycolysis do to glucose?

) Which of the above describes something about the electron transport chain in mitochondria?

) Which of the above describes the citric acid cycle?

Answer 1

D) produces oxygen and hydrogen gas by removing electrons from water: It describes photosystem II because photosystem II harvest the light energy and split water molecules to extract electrons, which results in the production of oxygen and hydrogen.

A) Gives 2 pyruvates, 2 NADH and 2 ATP without using oxygen: It describes glycolysis of glucose. In glycolysis, a glucose molecule is split into two molecules of pyruvate and a net gain of ATP is 2.

B) The part of oxidative phosphorylation where oxygen is converted to water: It describes something about the electron transport chain in mitochondria. It represents the last step in the process of ETC where oxygen and hydrogen are combined to form water molecules.

C) oxidization of carbons from Acetyl-CoA to CO₂, captures energy in the form of ATP and NADH: It describes the citric acid cycle because acetyl-CoA enters into the citric acid cycle in which CO_2, ATP, and NADH are produced.
