Energy Conversion Independent Practice

Cellular respiration results in the production of adenosine triphosphate (ATP) molecules for energy.

Select all of the substances that are produced along with ATP in the most efficient form of cellular respiration.

• water

• oxygen

• glucose

• carbon dioxide

• glycogen

Cells in the body use oxygen for cellular respiration.

Select the two sentences that correctly describe cellular respiration.

• ATP is produced

• ATP is consumed

• Carbon dioxide is absorbed

• Carbon dioxide is released

Sean felt the room become cooler. His body adjusts to enable him to survive. Which response did Sean have that enabled his body to continue to function correctly?

• an increase in cellular respiration which increases heat production

• sweating from the skin to lower inner heat levels

• opening of the capillaries in the skin to obtain more heat

• an increase in the metabolism which decreases heat from cells

Ava conducted an experiment to determine respiratory rates during different activities. She counted the number of breaths per minute. Ava noted that the number of breaths increases as physical activity increases. Why is there an increase in the number of breaths per minute as activity increases?

• As activity increases, more oxygen is exhaled.

• As activity increases, the oxygen needs of cells increase.

• As activity increases, breathing becomes more efficient.

• As activity increases, the rate of the heart beating increases.

What are the limitations of the diagram?

• The model shows synthesis of new compounds.

• The model is insufficiently labeled.

• The model represents two different processes, rather than one.

• The model contains too many arrows.

Which of the following correctly describes how a diagram of cellular respiration would differ from a diagram of photosynthesis?

• The cellular-respiration diagram would show electromagnetic waves as the final product.

• The cellular-respiration diagram would show glucose as the main source of energy.

• The cellular-respiration diagram would show energy stored in large protein molecules.

• The cellular-respiration diagram would show water as the main source of chemical energy.

Which statement explains how producers are dependent upon consumers for their survival?

• Consumers supply oxygen for producers to undergo aerobic respiration.

• Consumers produce carbon dioxide for producers to use during photosynthesis.

• Consumers provide chemical energy needed by producers for cellular respiration.

• Consumers make lactic acid that producers use in photosynthesis.
