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

Which step of cellular respiration is anaerobic?

Back

Glycolysis is the only step that occurs without oxygen.

Front

How many carbons from acetyl CoA remain after the Krebs Cycle?

Back

0 carbons remain after the Krebs Cycle; they are released as CO2.

Front

What donates the electron in photosynthesis?

Back

Water donates electrons in photosynthesis, specifically during the light-dependent reactions.

Front

Where are the electrons pumped during the electron transport chain in the mitochondria?

Back

Electrons are pumped into the intermembrane space during the electron transport chain.

Front

What is the main purpose of glycolysis?

Back

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

Front

What are the end products of the Krebs Cycle?

Back

The end products of the Krebs Cycle include ATP, NADH, FADH2, and CO2.

Front

What is oxidative phosphorylation?

Back

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

Front

What role does NADH play in cellular respiration?

Back

NADH carries electrons to the electron transport chain, where they are used to generate ATP.

Front

What is the significance of the intermembrane space in mitochondria?

Back

The intermembrane space is crucial for creating a proton gradient used to produce ATP during oxidative phosphorylation.
