Q

Equation of fermentation (anaerobic respiration by plant cells)

A

Glucose -> CO2 + Ethanol

17
Q

Explain why anaerobic respiration is less efficient than aerobic respiration

A

The glucose is not completely broken down, so less energy is released by the process.

18
Q

Why does breathing stay high after intense exercise?

A

To break down the lactic acid that has been produced

19
Q

Explain how breathing rate is linked to fitness

A

Fit people have lower resting breathing rates that do not increase as much during exercise

20
Q

Describe the effect of anaerobic respiration on cells

A

Production of lactic acid lowers the pH of the cell
