Define aerobic respiration + why it occurs.

Answer 1

• Aerobic respiration is the conversion of biochemical energy from nutrients into useable energy (ATP).
• This ATP is needed for metabolism, growth, movement, etc.

Question 2

What is the chemical equation for aerobic respiration?

Answer 2

C6H12O6 + 6O2 —-> 6CO2 + 6H2O +38ATP

Question 3

Define fermentation

Answer 3

Fermentation is the anaerobic process by which pyruvic acid is reduced to substances such as lactic acid (in animals) or ethanol (in plants) and a little ATP.
