What is the name of the process occurring along the inner membrane of mitochondria that pumps protons (H+) into the intermembrane space to drive synthesis of ATP?
A. anaerobic respiration
B. electron transport chain
C. krebs cycle
D. glycolysis
Answer: The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
Electrons are donated from one receptor to the next until they reach a proton pump that pumps protons into the intermembrane space and drives the synthesis of ATP.
