function best under certain environmental conditions
|
|
|
speeds up only one type of reaction. (Like a lock and key!!!) Example:Amylase-only breaks down starches.
|
|
|
can catalyze the same reaction over and over again.

None of the above

Detailed explanation-1: -Answer and Explanation: Enzymes are proteins that speed up chemical reactions.
Detailed explanation-2: -Enzyme: An enzyme is a biological catalyst. It speeds up a reaction by lowering or reducing the activation energy of the reaction. It can increase the rates of both forward and backward reactions.
Detailed explanation-3: -All enzymes isolated thus far are specific for the type of chemical reaction they catalyze-i.e., oxidoreductases do not catalyze hydrolase reactions, and hydrolases do not catalyze reactions involving oxidation and reduction.
Detailed explanation-4: -Enzymes are specific because different enzymes have differently shaped active sites. The shape of the active site of an enzyme is complementary to the shape of its specific substrate . This means they are the correct shapes to fit together. Temperature has an effect on enzyme activity.
