To act as a catalyst in chemical reactions
Answer:
d) The enzyme changes shape and can no longer speed up the reaction
Explanation:
Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
The heat from hotter object goes to the cooler object. when they reach the same temperature the heat flow will stop.
The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
