Question

A drug is tested in the laboratory and is found to create holes in both mitochondrial membranes. Scientists suspect that the drug will be harmful to human cells because it will inhibit A) the citric acid cycle. B) oxidative phosphorylation. C) glycolysis. D) the citric acid cycle and oxidative phosphorylation.

Answer 1

D. It will inhibit the citric acid cycle and oxidative phosphorylation.

Answer 2

The citric acid cycle and oxidative phosphorylation.

• The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step.
• Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle leads to the phosphorylation of ADP, producing ATP.

What is the function of mitochondria?

• It is known as the powerhouses of the cell.
• Mitochondria produce the energy necessary for the cell's survival and functioning.
• Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

Hence, D option is correct.
