Cellular Respiration Quiz

What is the overall purpose of cellular respiration?

• To store energy in the form of glucose

• To break down glucose and generate ATP for cellular processes

• To produce oxygen and glucose as energy sources

• To create energy by directly converting sunlight into ATP

Where does glycolysis occur in a cell?

• Nucleus

• Mitochondrial matrix

• Cytoplasm

• Inner mitochondrial membrane

Where does the Krebs Cycle take place?

• Cytoplasm

• Nucleus

• Inner mitochondrial membrane

• Mitochondrial matrix

What is the site of the Electron Transport Chain?

• Cytoplasm

• Nucleus

• Inner mitochondrial membrane

• Mitochondrial matrix

How does exercise impact cellular respiration?

• Exercise reduces the need for ATP and slows cellular respiration.

• Exercise increases oxygen demand and speeds up ATP production through cellular respiration.

• Exercise completely stops the Krebs Cycle, relying only on glycolysis.

• Exercise replaces cellular respiration with photosynthesis.

What happens to an individual when oxygen is no longer available?

• Cellular respiration stops entirely, and the cell dies immediately.

• Glycolysis continues, producing small amounts of ATP, and lactic acid builds up.

• The Electron Transport Chain becomes more efficient in producing ATP.

• The Krebs Cycle accelerates to compensate for oxygen loss.

Do plants perform cellular respiration? Why or why not?

• No, because they rely solely on photosynthesis for energy.

• Yes, because they need ATP for cellular processes just like animals.

• No, because they store all their energy as glucose without breaking it down.

• Yes, but only during the daytime when photosynthesis is occurring.

What is the balanced chemical equation for cellular respiration?

• 6CO2 + 6H2O → C6H12O6 + O2

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• 6CO2 + ATP → 6H2O + glucose

• C6H12O6 → CO2 + O2 + energy

What are the products of glycolysis?

• Pyruvate, ATP, and NADH

• Glucose and water

• Carbon dioxide and ATP

• Acetyl-CoA and oxygen

What are the reactants of the Krebs Cycle?

• Pyruvate and NADH

• Acetyl-CoA, NAD, and FAD

• Glucose and oxygen

• ATP and lactic acid
