Questions and Answers

What is the primary function of oxygen in aerobic respiration, and what is the resulting product?

Oxygen is used for oxidative phosphorylation, resulting in the production of ATP.

Where is the Electron Transport Chain (ETC) located in prokaryotic and eukaryotic cells?

In prokaryotes, the ETC is located in the plasma membrane, whereas in eukaryotes, it is located in the inner mitochondrial membrane.

What is the terminal electron acceptor in the Electron Transport Chain of eukaryotic cells?

Molecular oxygen (O2)

How do the Electron Transport Chains of prokaryotes and eukaryotes differ in terms of complexity?

Eukaryotic ETCs are more complex and involve additional electron carriers, whereas prokaryotic ETCs are simpler and have fewer electron carriers. Signup and view all the answers
