Section 2f Respiration

Question 1

Describe the process of respiration.

Answer 1

To release energy in cells (takes place in mitochondria).

Question 2

Describe the differences between aerobic and anaerobic respiration.

Answer 2

Aerobic respiration:

• Requires oxygen
• Lots of energy is released
• Produces water
• Produces CO2

Anaerobic respiration:

• Doesnt require oxygen
• Less energy is released
• Produces lactic acid
• Doesnt produce water or CO2 (except during yeast respiration).

Question 3

Write the word equation and balanced symbol equation for aerobic respiration.

Answer 3

Oxygen + Glucose -> Water + Carbon dioxide

6O2 + C6H12O6 -> 6H2O + 6CO2

Question 4

Write the word equation for anaerobic respiration.

Answer 4

Glucose -> Lactic Acid

Glucose -> Ethanol + Carbon dioxide
