|
|
Enzymes give energy to reactions.
|
|
|
Enzymes can be used by multiple substrates.
|
|
|
Enzymes lower energy needed to start a reaction.
|
|
|
All of these are true.

Detailed explanation-1: -The correct answer to this question is A) Enzymes lower the activation energy and the G produced from a reaction. Enzymes act as catalyzing agents that are responsible for the faster formation of products in different biochemical reactions.
Detailed explanation-2: -Like all catalysts, enzymes work by lowering the activation energy of chemical reactions. Activation energy is the energy needed to start a chemical reaction.
Detailed explanation-3: -Enzymes allow activation energies to be lowered. Enzymes lower the activation energy necessary to transform a reactant into a product.
Detailed explanation-4: -Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Detailed explanation-5: -The answer is A. Enzymes increase the rate of chemical reaction by lowering activation energy barriers. Enzymes are biological catalysts. Like all catalysts, they function by lowering the activation energy of a chemical reaction, which speeds the rate of the reaction.
