What is respiration?

• A process of converting light energy to chemical energy

• A process of storing energy in food

• A process of releasing energy from food

• A process of making food

What is photosynthesis?

• A process of converting light energy to chemical energy

• A process of releasing energy from food

• A process of making food

• A process of storing energy in food

What is the main difference between respiration and photosynthesis?

• Respiration releases energy from food, while photosynthesis converts light energy to chemical energy

• Respiration converts light energy to chemical energy, while photosynthesis releases energy from food

• Respiration and photosynthesis are the same process

• Respiration and photosynthesis have no relation to energy

What is the chemical equation for aerobic respiration?

• Glucose + oxygen -> carbon dioxide + water + energy

• Carbon dioxide + water -> glucose + oxygen + energy

• Oxygen + water -> glucose + carbon dioxide + energy

• Glucose + water -> carbon dioxide + oxygen + energy

What is the role of enzymes in biological processes?

• To convert energy into matter

• To stop reactions completely

• To speed up reactions without being used up

• To slow down reactions

What happens if there is a shortage of oxygen during respiration?

• The rate of respiration remains constant

• The rate of respiration stops completely

• The rate of respiration decreases

• The rate of respiration increases
