Test Review: Chemical Reactions in Living Things

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in photosynthesis, used by plants to produce glucose.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, carbon dioxide, and water.

Front

What happens to carbon in food molecules during cellular respiration?

Back

Carbon in food molecules is released as carbon dioxide during cellular respiration.

Front

What type of energy is released when a tortilla chip is burned?

Back

Chemical energy is released as light, thermal, and sound energy when a tortilla chip is burned.

Front

What is the significance of the arrow in a food chain?

Back

The arrow indicates the flow of energy and nutrients from one organism to another.

Front

What happens to the level of CO2 in the body during exercise?

Back

The level of CO2 increases as more oxygen is consumed and more carbon dioxide is produced during cellular respiration.

Front

What type of energy do plants use to produce chemical energy?

Back

Plants use light energy from the sun to produce chemical energy during photosynthesis.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose.
