BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes perform the critical task of lowering a reaction’s activation energy-that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Detailed explanation-2: -Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. For example: Enzymes bring reactants together so they don’t have to expend energy moving about until they collide at random.

Detailed explanation-3: -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-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: -Some reactions require a great amount of activation energy, which acts as an energy barrier making it difficult for the reactants to come together and react. Enzymes reduce the energy needed for the reactants to come together, increasing the rate of the chemical reaction.
