BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex. The reaction then occurs, converting the substrate into products and forming an enzyme products complex.

Detailed explanation-2: -In order for a product molecule to be generated, a substrate molecule must first bind to the active site of an enzyme and be transformed into a product molecule. An example of a product molecule produced by an enzyme is phosphoenolpyruvate produced by the enzyme enolase.

Detailed explanation-3: -The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.

Detailed explanation-4: -One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

Detailed explanation-5: -Energy is also released during the reaction. The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start. Compare the activation energy with and without the enzyme. Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react.
