WG AP/DP Cellular Respiration Video

What is the primary form of energy that cells use to power their processes?

• Glucose

• ADP

• ATP

• Oxygen

Where is the energy stored within an ATP molecule?

• In the adenine base

• In the ribose sugar

• In the bonds between phosphate groups

• In the chemical bonds of the entire molecule

How does the chemical equation for cellular respiration relate to the chemical equation for photosynthesis?

• They are identical.

• They are completely unrelated.

• The reactants of one are the products of the other.

• Photosynthesis produces ATP, while cellular respiration consumes it.

What is the first step of cellular respiration, and where does it occur?

• Krebs Cycle, Mitochondria

• Glycolysis, Cytoplasm

• Electron Transport Chain, Mitochondria

• Photosynthesis, Chloroplast

What are the net products of glycolysis from one glucose molecule?

• 2 ATP, 2 NADH, 2 Pyruvate

• 4 ATP, 2 NADH, 2 Pyruvate

• 2 ATP, 2 FADH2, 2 Pyruvate

• 6 ATP, 6 NADH, 2 Pyruvate

What are the direct products of the Krebs Cycle per glucose molecule?

• 2 ATP, 6 NADH, 2 FADH2, Carbon Dioxide

• 2 ATP, 2 NADH, 2 FADH2, Carbon Dioxide

• 4 ATP, 6 NADH, 2 FADH2, Water

• 6 ATP, 8 NADH, 4 FADH2, Carbon Dioxide

What is the primary role of oxygen in the Electron Transport Chain?

• To produce ATP directly.

• To act as the final electron acceptor.

• To create the proton gradient.

• To convert glucose into pyruvate.

What is the maximum theoretical net ATP yield from one glucose molecule during cellular respiration in a perfect scenario?

• 2 ATP

• 34 ATP

• 38 ATP

• 36 ATP

How does cyanide poisoning affect cellular respiration?

• It blocks the breakdown of glucose during glycolysis.

• It prevents the formation of pyruvate from glucose.

• It inhibits a step in the electron transport chain.

• It stops the citric acid cycle from producing ATP.

What is the total ATP yield from glycolysis, the citric acid cycle, and oxidative phosphorylation in cellular respiration?

• 34 ATP

• 36 ATP

• 38 ATP

• 40 ATP
