AP Biology Unit 3 Review without enzymes

Front

What is a high energy hydrogen carrier?

Back

High energy hydrogen carriers are molecules that transport hydrogen atoms and electrons during cellular respiration and photosynthesis. Examples include NADH and FADH2.

Front

Which molecule isn't a high energy hydrogen carrier?

Back

Oxygen is not a high energy hydrogen carrier.

Front

What process breaks down glucose into pyruvic acid?

Back

Glycolysis is the process that breaks down glucose into pyruvic acid.

Front

How many ATPs are required for the Calvin cycle?

Back

The Calvin cycle requires 9 ATPs.

Front

What is the output of oxidative phosphorylation?

Back

The output of oxidative phosphorylation is ATP.

Front

What happens to the carbon atoms in glucose during cellular respiration?

Back

The carbon atoms in glucose are exhaled as CO2 during cellular respiration.

Front

Define glycolysis.

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration, where ATP is produced using the energy released from the electron transport chain.
