AP Biology - Cellular Respiration

Front

What is the final electron acceptor of aerobic respiration?

Back

Oxygen, which allows electron flow to continue.

Front

What is the main job of the electron carriers in cellular respiration?

Back

Transport electrons and hydrogen atoms to the electron transport chain.

Front

How is cellular respiration related to photosynthesis?

Back

It is the reverse reaction of photosynthesis.

Front

Which statement about glycolysis is false?

Back

Glycolysis occurs in the mitochondria.

Front

What supplies the electrons that transfer energy to pump protons across the inner mitochondrial membrane?

Back

NADH and FADH2.

Front

What are the products of glycolysis?

Back

2 ATP, 2 Pyruvates, and 2 NADH.

Front

Where does glycolysis occur?

Back

In the cytoplasm of the cell.

Front

What is the primary purpose of the citric acid cycle?

Back

To produce electron carriers (NADH and FADH2) for the electron transport chain.

Front

What is chemiosmosis?

Back

The process of using a proton gradient to drive ATP synthesis.

Front

What is the role of oxygen in cellular respiration?

Back

It acts as the final electron acceptor in the electron transport chain.
