The transport of pyruvate into mitochondria depends on the proton-motive force across the inner mitochondrial membrane. How does pyruvate enter the mitochondrion?
A) active transport
B) diffusion
C) facilitated diffusion
D) through a channel
E) through a pore

Question

Quizplus · Accepted Answer

Active transport is required for the transport of pyruvate into mitochondria, as it depends on the proton-motive force across the inner mitochondrial membrane, indicating the need for energy input to move pyruvate against its concentration gradient.
