D
Glycolysis
Verified step by step guidance
1
Understand the process of oxidative phosphorylation, which occurs in the mitochondria and is crucial for ATP production.
Recognize that oxidative phosphorylation involves two main components: the electron transport chain and chemiosmotic coupling.
The electron transport chain is responsible for transferring electrons through a series of complexes, ultimately leading to the pumping of protons across the mitochondrial membrane.
Chemiosmotic coupling refers to the use of the proton gradient created by the electron transport chain to drive ATP synthesis via ATP synthase.
Identify that glycolysis is a separate process that occurs in the cytoplasm and is not part of oxidative phosphorylation, as it does not involve the electron transport chain or chemiosmotic coupling.
