Flashcards

What is the role of oxygen in aerobic respiration?

Oxygen acts as the final electron acceptor, accepting electrons at the end of the electron transport chain.

What is aerobic respiration?

The process using oxygen to break down glucose for energy production, generating ATP, carbon dioxide, and water.

What is the significance of aerobic respiration?

The main energy-producing pathway for most organisms, using oxygen as the final electron acceptor.

What is the electron transport chain?

A series of reactions where electrons are passed from one molecule to another, releasing energy that is used to generate ATP.

What is fermentation?

Fermentation is an anaerobic process that produces a small amount of ATP, but doesn't involve the electron transport chain.
