Where in a eukaryotic cell is most ATP made during oxidative phosphorylation?
A
In the nucleus, during DNA replication
B
In the Golgi apparatus, during protein modification and sorting
C
On the plasma membrane, through membrane receptor signaling
D
On the inner mitochondrial membrane (cristae), where the electron transport chain and ATP synthase are located
Verified step by step guidance1
Understand that oxidative phosphorylation is the process by which ATP is produced using energy derived from electrons transferred through the electron transport chain.
Recall that in eukaryotic cells, the electron transport chain and ATP synthase complexes are embedded in the inner mitochondrial membrane, specifically in the folds called cristae.
Recognize that the inner mitochondrial membrane provides a large surface area for these protein complexes, facilitating efficient ATP production.
Note that other cellular locations mentioned, such as the nucleus, Golgi apparatus, and plasma membrane, do not host the electron transport chain or ATP synthase and thus are not sites of oxidative phosphorylation.
Conclude that most ATP during oxidative phosphorylation is made on the inner mitochondrial membrane (cristae) due to the presence of the electron transport chain and ATP synthase.
