In a typical eukaryotic cell, where is most ATP generated during oxidative phosphorylation?
A
In the Golgi apparatus during protein glycosylation
B
In lysosomes during hydrolytic digestion
C
In the nucleus during DNA replication
D
At the inner mitochondrial membrane by ATP synthase using the proton gradient
Verified step by step guidance1
Understand that ATP generation during oxidative phosphorylation occurs in eukaryotic cells primarily within mitochondria, which are known as the powerhouse of the cell.
Recall that oxidative phosphorylation involves the electron transport chain creating a proton gradient across the inner mitochondrial membrane.
Recognize that ATP synthase, an enzyme embedded in the inner mitochondrial membrane, uses this proton gradient to synthesize ATP from ADP and inorganic phosphate.
Eliminate other organelles mentioned: the Golgi apparatus is involved in protein modification, lysosomes in digestion, and the nucleus in DNA replication, none of which generate ATP via oxidative phosphorylation.
Conclude that most ATP during oxidative phosphorylation is generated at the inner mitochondrial membrane by ATP synthase utilizing the proton gradient.
