AP Biology - Cellular Respiration

Front

What is cellular respiration?

Back

The catabolism of glucose to transfer energy to ATP.

Front

Is photosynthesis an energy storing process and cellular respiration an energy releasing process?

Back

True.

Front

After strenuous exercise, what would a muscle cell contain decreased amounts of and increased amounts of?

Back

Decreased amounts of oxygen and increased amounts of lactic acid.

Front

What is the main purpose of fermentation?

Back

To replenish NAD+ for glycolysis.

Front

What happens during chemiosmosis?

Back

ATP is synthesized when H+ ions move through a channel in ATP synthase.

Front

What is the role of NADH in cellular respiration?

Back

NADH carries electrons to the electron transport chain.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, Krebs cycle, and electron transport chain.

Front

What is the net gain of ATP from glycolysis?

Back

2 ATP.

Front

What is the function of the Krebs cycle?

Back

To produce electron carriers (NADH and FADH2) and ATP.

Front

What is oxidative phosphorylation?

Back

The process of ATP production that occurs in the electron transport chain.
