Cell Structure and Function: Mitochondrial Inner Membrane

APBIO-YLS21D

Which of the following is the functional significance of the convoluted folded shape of the inner membrane of the mitochondria, referred to as the cristae?

A

It allows for more electron transport chains and ATP synthase molecules to fit, which allows for faster ATP regeneration.

B

It allows for faster removal of carbon dioxide, which prevents the formation of carbonic acid in the matrix, slowing down ATP regeneration.

C

It allows for the faster absorption of oxygen by the mitochondria and therefore greater efficiency of glycolysis.

D

It allows for the faster absorption of lactate molecules, which allows the Krebs cycle to run faster resulting in faster ATP regeneration.
