respiration

What is the primary characteristic of cellular respiration?

• An endothermic reaction that creates energy.

• A process that builds glucose molecules.

• An exothermic reaction that transfers energy from glucose.

• A reaction that only occurs when oxygen is absent.

Which of the following is a use of energy released during respiration in organisms?

• Breaking down larger molecules into smaller ones.

• Building larger molecules from smaller ones.

• Decreasing body temperature.

• Reducing muscular contraction.

Which statement accurately describes aerobic respiration?

• It occurs without oxygen and produces lactic acid in humans.

• It is the most efficient way to transfer energy from glucose and occurs in mitochondria.

• It is a process that only occurs in plants.

• It produces ethanol and carbon dioxide in animals.

What is a key difference between anaerobic respiration in humans and in plants/yeast?

• Humans produce carbon dioxide, while plants/yeast produce lactic acid.

• Humans produce lactic acid, while plants/yeast produce ethanol and carbon dioxide.

• Anaerobic respiration is efficient in humans but inefficient in plants/yeast.

• Anaerobic respiration in humans requires oxygen, but in plants/yeast it does not.
