AP Biology Unit 3: Cellular Energetics

Front

What is cellular respiration?

Back

The breakdown of glucose to release ATP.

Front

Where does the carbon come from that is used to form glucose?

Back

CO₂ in the air.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes speed up reaction rates by lowering activation energy.

Front

What is the function of NADP+ in cellular processes?

Back

NADP+ acts as an electron carrier.

Front

Why can enzymatic reactions become saturated?

Back

There are a limited number of enzyme molecules present.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells.

Front

What are the main stages of cellular respiration?

Back

Glycolysis, Krebs cycle, and oxidative phosphorylation.

Front

What is glycolysis and where does it occur?

Back

Glycolysis is the process of breaking down glucose into pyruvate, occurring in the cytoplasm.

Front

What is the Krebs cycle and its significance?

Back

The Krebs cycle processes acetyl-CoA to produce electron carriers for the electron transport chain.

Front

What is oxidative phosphorylation?

Back

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