Respiration and Energy Transfer

Front

What is respiration?

Back

Respiration is a chemical reaction carried out in all living organisms to release energy from glucose.

Front

What are the two types of respiration?

Back

Aerobic respiration (with oxygen) and anaerobic respiration (without oxygen).

Front

What are the waste products of aerobic respiration?

Back

Carbon dioxide and water.

Front

How is energy transferred in respiration?

Back

Energy is transferred in the form of ATP (Adenosine Triphosphate).

Front

What is the word equation for aerobic respiration?

Back

Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP).

Front

What is the balanced chemical equation for aerobic respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP).

Front

What is anaerobic respiration?

Back

Anaerobic respiration is the chemical reaction in cells that breaks down nutrient molecules to release energy without using oxygen.

Front

What are the products of anaerobic respiration in animals?

Back

Lactic acid and a small amount of energy.
