AP Biology- Respiration

Front

What is the primary process that produces the most ATP per molecule of glucose?

Back

Aerobic respiration.

Front

Which molecule is not an end product of the Kreb's cycle?

Back

Pyruvate.

Front

What 2-carbon molecule enters the Kreb's Cycle?

Back

Acetyl CoA.

Front

What role does NADH play during cellular respiration?

Back

It delivers its electron load to the first electron carrier molecule.

Front

Which process occurs in the presence of oxygen and produces significantly more ATP than glycolysis alone?

Back

Aerobic respiration.

Front

What are the main stages of cellular respiration?

Back

Glycolysis, Kreb's cycle, and oxidative phosphorylation.

Front

What is the main purpose of glycolysis?

Back

To break down glucose into pyruvate, producing a small amount of ATP and NADH.

Front

Where does the Kreb's cycle take place in the cell?

Back

In the mitochondria.

Front

What is the significance of oxygen in aerobic respiration?

Back

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

Front

What are the end products of the Kreb's cycle?

Back

Carbon dioxide, ATP, NADH, and FADH2.
