LIFE SCIENCE

Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.

Detailed explanation-2: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.

Detailed explanation-3: -Enzymes and activation energy A substance that speeds up a chemical reaction-without being a reactant-is called a catalyst.

Detailed explanation-4: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

Detailed explanation-5: -They may bring the reactants together making it easier for them to interact with each other instead of expending energy moving about until they collide at random. They may guide the reaction towards a different pathway that requires lower activation energy. More items •12-May-2022
