Question

a mitochondrion is having a problem creating enough energy to build new molecules. which problem most likely exists with the mitochondrion?
a. the ribosomes have produced too many proteins.
b. there are too many hydrogen ions outside the membrane.
c. the hydrogen pump may not be functioning properly.
d. there are too many glucose molecules inside the cell.

Explanation:

Mitochondria produce energy through the electron - transport chain and chemiosmosis. The hydrogen pump (ATP synthase) uses the proton gradient (hydrogen ions) to make ATP. If the hydrogen pump is not working properly, energy production will be affected. Ribosome function is related to protein synthesis not mitochondrial energy production. Excess hydrogen ions outside the membrane is part of the normal gradient for energy production, not a problem in itself. Glucose molecules inside the cell are related to glycolysis and not directly to mitochondrial energy - production issues.

Answer:

C. The hydrogen pump may not be functioning properly.
