What is the function of ATP synthase in the electron transport chain?
A
To pump protons across the mitochondrial membrane
B
To transport electrons between complexes
C
To synthesize ATP from ADP and inorganic phosphate
D
To oxidize NADH to NAD+
Verified step by step guidance1
Understand the role of ATP synthase in cellular respiration, specifically in the electron transport chain, which is part of oxidative phosphorylation.
Recognize that ATP synthase is an enzyme located in the inner mitochondrial membrane, crucial for the production of ATP.
Learn that ATP synthase utilizes the proton gradient created by the electron transport chain to drive the synthesis of ATP from ADP and inorganic phosphate.
Identify that the electron transport chain pumps protons across the mitochondrial membrane, creating a high concentration of protons in the intermembrane space.
Comprehend that the flow of protons back into the mitochondrial matrix through ATP synthase provides the energy needed for the phosphorylation of ADP to ATP.
