Answer;
The enzyme structure begins to break down
intermolecular bonds are broken
enzyme molecules gain kinetic energy.
Explanation;
Enzymes are proteins that play an important function in the body of catalyzing reactions in the body.
Enzymes work best at optimum temperature; low temperature lower than optimum temperatures deactivates them and higher temperature denatures them.
The shape of an enzyme depends on its temperature; when they get too warm they get loose, and at very low temperatures they get too tight. At optimum temperature or at the right temperature then they are just at the right shape and the chemical reactions they catalyze will be at optimal rate.
The sun heats up water on the earth which causes the water to evaporate thefore the hot water vapor rises up to higher altitudes where it's colder which causes condensation, without the sun this could never happen
