What is the main goal of cell respiration?

to break down glucose in the form of ATP

to make ATP that we use for energy

Respiration is a byproduct of photosynthesis

Which of the following organism depend on the process of cell respiration for survival?

All organisms that break down glucose for food; including plants and animals

Animals, some algae, and phytoplankton but NOT plants

Only animals, since they go through process of cell respiration

Which of the following best describes photosynthesis?

Photosynthesis converts radiant energy into chemical energy.

Photosynthesis produces carbohydrates.

Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis.

Plants use chlorophyll, water, and carbon dioxide to make sugar.

Which of the following equations represents the overall chemical reaction for photosynthesis?

6CO 2 + 6H 2 O→ C 6 H 12 O 6 + 6O 2

6O 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2

C 6 H 12 O 6 + 6H 2 O→ 6O 2 + 6O 2

6O 2 + 6H 2 O→ C 6 H 12 O 6 + 6CO 2

Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes?

Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.

Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.

Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.

Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.

produces large amounts of energy
