Cellular respiration is an exothermic reaction. What does this mean?
It is a reaction which takes in energy from the environment.
The reaction goes more quickly when the environment is warmer.
Energy is transferred to the environment by respiration.
The reaction of respiration slow down at high temperatures.
In which part of a cell does aerobic respiration occur?

Ethanol and water
What happens in your muscles during vigorous exercise?
Anaerobic respiration occurs
Lactic acid builds up
Low pH leads to pain and muscle cramp
All of the above
Which of the following is NOT a disadvantage of anaerobic respiration?
Lactic acid lowers the pH inside cells.
Anaerobic respiration is an exothermic reaction.
Anaerobic respiration releases comparatively little energy.
Ethanol produced by plant cells can damage cell membranes.
