Q

Describe temperature and its effect on the rate of cellular respiration

A

As the temperature moves out of the optimal temperature range, the rate of the enzyme reactions and therefore the rate at which cellular respiration occurs, will slow down

Q

Describe the effect of glucose availability on the rate of cellular respiration

A

If the temperature remains constant, increasing glucose availability will increase reaction rate to a maximum point
