AP Bio Insta-Review Topic 3.6: Cellular Respiration

Front

What is the first step of cellular respiration?

Back

Glycolysis is the first step of cellular respiration, where glucose is broken down into pyruvate.

Front

Is ATP synthesized in the electron transport chain?

Back

False. ATP is synthesized during oxidative phosphorylation, which occurs after the electron transport chain.

Front

Do prokaryotes perform an electron transport chain on their plasma membrane?

Back

True. Prokaryotes have their electron transport chain located on their plasma membrane.

Front

Which enzyme in the cristae adds the P to ADP?

Back

ATP Synthase is the enzyme that adds a phosphate group to ADP to form ATP.

Front

Where does the electron transport chain of cellular respiration occur?

Back

The electron transport chain occurs in the cristae of the mitochondria.

Front

What is the main purpose of glycolysis?

Back

The main purpose of glycolysis is to convert glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What are the end products of the Krebs Cycle?

Back

The end products of the Krebs Cycle include carbon dioxide, ATP, NADH, and FADH2.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the mitochondria, driven by the electron transport chain and chemiosmosis.

Front

What is the significance of the cristae in mitochondria?

Back

Cristae increase the surface area for the electron transport chain and ATP synthesis.
