Cellular Respiration Review

Front

What is cellular respiration?

Back

Cellular respiration is the process by which carbon-based molecules from food and oxygen are broken down to provide the energy to make ATP.

Front

What is chemiosmosis?

Back

Chemiosmosis is the process where H+ ions diffuse down their concentration gradient through ATP Synthase, providing energy to make ATP.

Front

What is the primary process that breaks down sugars to produce ATP in the presence of oxygen?

Back

Cellular Respiration.

Front

How many ATP can be produced from one molecule of glucose?

Back

30-38 ATP, depending on how much the cell uses the H+ concentration gradient for other processes.

Front

What role does the electron transport chain play in cellular respiration?

Back

The electron transport chain pumps hydrogen ions from the matrix to the intermembrane space.

Front

What is the main purpose of ATP in cellular respiration?

Back

ATP serves as the primary energy currency of the cell, providing energy for various cellular processes.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, the Krebs cycle, and the electron transport chain.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What happens during the Krebs cycle?

Back

The Krebs cycle processes pyruvate to produce electron carriers (NADH and FADH2) and releases CO2.

Front

What is the role of oxygen in cellular respiration?

Back

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