Respiration

Question 1

Describe the process of cellular respiration.

Answer 1

An exothermic reaction which occurs continuously in living cells to release energy for metabolic processes

Question 2

What are the reactants and products in respiration?

Answer 2

Glucose + Oxygen –> Water + Carbon Dioxide

(Energy is released)

Question 3

Describe the aspects of aerobic respiration.

Answer 3

• Aerobic respiration occurs when lots of oxygen is available
• It releases a lot of energy, so it is efficient

Question 4

Describe the aspects of anaerobic respiration.

Answer 4

• Anaerobic respiration occurs in the presence of little or no oxygen
• Glucose in cells is converted to lactic acid in muscles, which causes cramp
• It releases little energy, so anaerobic is less efficient

Question 5

Plants can respire without oxygen too.

Give the word equation for anaerobic respiration in plants.
