In graphs of enzyme activity versus temperature, activity increases up to a certain temperature and then decreases again. What is the mechanism that best explains this pattern?a. As temperatures increase, substrates collide with the enzyme more, but even higher temperatures cause too much enzyme movement and the enzyme denatures.
b. Enzymes have preferred temperature optima.
c. As temperatures increase, substrates collide with the enzyme more, but even higher temperatures slow substrate movement.
d. As temperatures increase, more cofactors will bind to enzymes, but even higher temperatures will decrease cellular cofactor concentrations to a level that decreases enzyme activity.

"As temperatures increase, substrates collide with the enzyme more, but even higher temperatures cause too much enzyme movement and the enzyme denatures."

Explanation:

Optimum temperature for Enzyme activity:

As there is an optimum amount of heat required for an enzymatic activity. At first the binding site of the enzyme is prepared for binding of the enzyme and the substrate, after which the enzyme is activated for proper function or carrying out the enzymatic reaction.

Along with that if the temperature inside the cell or outside in the environment is taken to extreme levels then the enzyme will lose its physical properties and will eventually denature.

Which will cause most of the reaction to be halted and the conclusion can be of catastrophic level, as there will be less productivity inside the living organisms body and same for the energy production on cellular level.
