Mitochondrial Structure and Function

APBIO-VZRYL3

In humans, the mitochondria found in type I muscle fibers have inner membranes with a surface area approximately five times the area of the outer membrane.

A high school student has a rare genetic disorder in which the mitochondria in her muscle cells have inner membranes with a surface area less than three times the area of the outer membrane.

Which of the following would be a potential consequence of this disorder?

A

The student's muscle cells would be able to produce more ATP per unit time via oxidative phosphorylation than most other people's muscle cells.

B

The student's muscle cells would be able to produce less ATP per unit time via oxidative phosphorylation than most other people's muscle cells.

C

The student's muscle cells would be able to produce more ATP per unit time via substrate level phosphorylation than most other people's muscle cells.

D

The student's muscle cells would be more permeable to glucose than most other people's muscle cells.
