For each 10°C rise in temperature, the rate of biological processes roughly increases by:

Correct option is A

Q10 Temperature Coefficient:
· The Q10 coefficient measures the rate of change in biological or chemical processes due to a 10°C increase in temperature.
· For most biological processes, the Q10 value is approximately 2, meaning the rate doubles for every 10°C rise in temperature.
Impact on Enzymatic Reactions:
· Enzymatic activity increases with temperature as molecules collide more frequently, accelerating reactions.
· Beyond a certain point, enzymes denature, causing the rate to decline.
