2.28 Electron Transport Chain Flashcard

Front

What is Cellular Respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Why is Cellular Respiration considered aerobic?

Back

Because it requires oxygen to proceed.

Front

What is the role of ATP synthase in cellular respiration?

Back

ATP synthase is an enzyme that creates ATP during the process of chemiosmosis.

Front

What do FADH2 and NADH contribute to the electron transport chain?

Back

They provide electrons to the electron transport chain.

Front

What is a key reactant for the electron transport chain?

Back

Oxygen is a key reactant for the electron transport chain.

Front

What process enables ATP synthase to function?

Back

Diffusion of protons (H+) across the membrane enables ATP synthase to function.

Front

What is the main product of the electron transport chain?

Back

The main product is ATP, which is generated through oxidative phosphorylation.

Front

What is chemiosmosis?

Back

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient, which drives ATP synthesis.

Front

What is the significance of the proton gradient in the electron transport chain?

Back

The proton gradient created by the electron transport chain is essential for ATP production.

Front

What are the two main types of electron carriers in cellular respiration?

Back

The two main types are NADH and FADH2.
