|
|
|
Each enzyme is specific because of its shape and catalyzes only certain reactions
|
Explanation:
Detailed explanation-1: -The enzyme is not destroyed during the reaction and is used over and over. A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.
Detailed explanation-2: -So, the correct answer is ‘Enzymes are used up in reactions’.
Detailed explanation-3: -Answer is (1) Enzymes are non-specific for a reaction and substrate.
Detailed explanation-4: -Enzymes provide help with facilitating chemical reactions within each cell. Since they are not destroyed during the process, a cell can reuse each enzyme repeatedly. Enzymes help with specific functions that are vital to the operation and overall health of the body.
