D) citric acid cycle

Answer 1

$\textbf{\large{Answer -}}$

During which process is water produced?
A) Acetyl COA formation
B) Electron transport chain✔✔✔
C) Alcohol fermentation
D) citric acid cycle

Explanation :

Electron transport chain is the last stage of cellular respiration and the other stages are glycolysis and citric acid cycle.

Electron carrier is reduced during glycolysis and the citric acid cycle to $NADH + {H}^{+}$ and $FADH_{2}$ . These electron carriers later kn donate electrons and protons to the electron carrier proteins of the electron transport chain. The final electron acceptor is oxygen. And at last, with oxygen, electrons and protons form water.

Answer 2

Answer:

(B) Electron transport chain will be the correct answer

Explanation:

The electron transport chain is a sequence of redox processes that occur during cellular respiration, as well as subsequent stages of glycolysis and the citric acid cycle where glucose metabolism can utilize ambient oxygen.

Electron carriers predominantly decrease oxygen in the presence of glucose as a prerequisite during glycolysis and the citric acid cycle, and following this ETC process, water molecules are generated in the presence of mitochondria during aerobic respiration.
