Question

Electric charge drives this series of pumps and triggers known as ETS reactions. What is the net effect of these reactions?

A. ATP become ADP as hydrogen ions are pumped back and forth across the matrix.
B. ATP is created as oxygen is consumed, and water is produced along the way. C. Energized molecules, such as NAD and FAD, accept electrons as ATP is produced.
D. NADH and FADH2 form water molecules that pump ATP back and forth across the matrix.

Answer 1

The answer is C. ATP is created as oxygen is consumed and water is produced along the way.

Answer 2

The correct answer is:

B. ATP is created as oxygen is consumed, and water is produced along the way

Explanation:

Most eukaryotic cells have mitochondria, which generate ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrial internal membrane, electrons from NADH and FADH2 pass within the electron transport chain to oxygen, which is degraded to water.
