Unit 3: Energy and Matter (Exam Review)

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of cellular respiration that occurs without oxygen, allowing some organisms to generate energy.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that are present before a chemical reaction occurs, found on the left side of the arrow in a chemical equation.

Front

What does the law of conservation of matter state?

Back

The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction.

Front

What is the purpose of photosynthesis?

Back

The purpose of photosynthesis is to convert light energy into chemical energy in the form of sugars.

Front

How does carbon move through a food chain?

Back

Carbon moves through a food chain as producers take in carbon dioxide and consumers release it.

Front

What is cellular respiration?

Back

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

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction, found on the right side of the arrow in a chemical equation.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What role do producers play in the carbon cycle?

Back

Producers take in carbon dioxide from the atmosphere and convert it into organic matter through photosynthesis.
