Cellular Respiration Review

Energy is produced during cellular respiration and stored in the form of ______.

• APT

• ATP

• TPA

• PTA

Answer explanation

ATP (Adenosine Triphosphate) is the body's currency for energy. It is the main output of cellular respiration.

Which of the following represents the process of cellular respiration?

• Glucose + water + oxygen --> carbon dioxide + energy

• Carbon dioxide + water + energy --> glucose + oxygen

• Glucose + oxygen --> carbon dioxide + water + energy

• Glucose + water + carbon dioxide --> oxygen + energy

Answer explanation

Remember that cellular respiration has 2 inputs (glucose and oxygen) and 3 outputs (carbon dioxide, water and energy).

Where does cellular respiration take place?

• Mitochondria

• Cell Membrane

• Nucleus

• Ribosomes

Answer explanation

The mitochondria is nicknamed as the powerhouse of the cell because it is where energy is produced through the process of cellular respiration.

Based on the diagram, which of the following materials does cellular respiration produce that plants use in photosynthesis?

• Carbon dioxide and water

• Carbon dioxide and energy

• Glucose and oxygen

• Sunlight, carbon dioxide and water

Answer explanation

Out of the three outputs of cellular respiration (carbon dioxide, water and energy), only carbon dioxide and water are used by plants in photosynthesis.

Why is cellular respiration important to animals?

• It produces glucose.

• It forms carbon dioxide.

• It uses oxygen.

• It stores energy in ATP.

Answer explanation

Although it's true that cellular respiration forms carbon dioxide and uses oxygen, the main reason why it is important to animals is that it stores energy in ATP.

Which of the following correctly explains why both plants and animals need to undergo cellular respiration?

• Both plants and animal cells need chemical energy to carry out cellular processes.

• Plant cells do not need chemical energy for cellular processes and animal cells do.

• Plants need to store more chemical energy and animals need chemical energy for cellular processes.

• Plant cells already have chemical energy stored in them and animal cells need chemical energy for cellular processes

Answer explanation

All living organisms (including plants and animals) need chemical energy to carry out cellular processes.

For respiration to occur, the ____________________ must be present.

• Chloroplasts and nucleus

• Nucleus and cell membrane

• Cell wall and cell membrane

• Mitochondria and chloroplasts

Answer explanation

Cellular respiration occurs in the mitochondria while photosynthesis occurs in the chloroplast. The two processes are interdependent and one cannot occur without the other.
