What is the significance of cellular respiration in living organisms?

• It allows cells to produce energy from glucose, which is essential for survival.

• It helps cells to divide and reproduce.

• It is responsible for the movement of substances across cell membranes.

• It is the process by which cells eliminate waste products.

Multiple Choice

Which of the following is the main purpose of cellular respiration?

• To break down glucose to make ATP

Open Ended

Where do NADH and FADH2 go after the Krebs Cycle and what do they carry?

Multiple Choice

About how many ATP molecules are created by aerobic cellular respiration?

• 0

• 2

• 36

• 12

Multiple Choice

What role does ATP synthase play in the electron transport chain, and how does the movement of H+ ions contribute to ATP production?

• ATP synthase breaks down ATP to release energy

• ATP synthase allows H+ ions to diffuse back into the matrix, using their energy to join ADP and P to form ATP

• ATP synthase transports electrons across the membrane

• ATP synthase produces water by combining H+ ions and O2

Multiple Choice

Which of the following statements about the electron transport chain is correct?

• Electrons are transferred from NADH and FADH2 to oxygen, forming water.

• ATP is produced directly by the movement of electrons.

• CO2 is released during the electron transport chain.

• The electron transport chain occurs in the cytoplasm.

Multiple Choice

Which of the following happen during the Electron Transport Chain?

• High energy electrons travel down the ETC, pumping H⁺'s into the intermembrane space

• H⁺'s travel down the ETC, pumping high energy electrons into the intermembrane space

• H⁺'s diffuse through ATP Synthase, turning it so it can make ATP

Multiple Choice

What are the 3 stages of cellular respiration in the correct order?

• Krebs, Glycolysis, Electron Transport Chain

• Glycolysis, Krebs, Electron Transport Chain

• Electron Transport Chain, Krebs, Glycolysis

Multiple Choice

During which step of cellular respiration is the majority of the ATP created?

• Fermentation

• Glycolysis

• Krebs Cycle
