Verified step by step guidance

Understand the process of cellular respiration, which consists of glycolysis, the citric acid cycle, and oxidative phosphorylation.

Recognize that oxidative phosphorylation is the final stage of cellular respiration, where ATP is produced using energy derived from electrons transferred through the electron transport chain.

Identify the location of the electron transport chain, which is embedded in the inner mitochondrial membrane.

Recall that the inner mitochondrial membrane is crucial for creating a proton gradient, which drives ATP synthesis during oxidative phosphorylation.

Conclude that oxidative phosphorylation occurs in the inner mitochondrial membrane, as it is where the electron transport chain and ATP synthase are located.
