Question

what type of macromolecule is an enzyme
describe activation energy
describe the idea of a lock and key with an enzyme
what is the substrate
what is the activation site
what is meant by the product

Explanation:

1. Enzymes are proteins. Proteins are large, complex macromolecules made up of amino - acid chains.
2. Activation energy is the minimum amount of energy that reactants must absorb before a chemical reaction will start. It acts as an energy barrier.
3. The lock - and - key model describes how an enzyme's active site (the lock) has a specific shape that only fits a particular substrate (the key). This specificity allows for efficient catalysis.
4. The substrate is the reactant molecule upon which an enzyme acts. The enzyme binds to the substrate at its active site.
5. The active site is the region on the surface of an enzyme where the substrate binds and the chemical reaction occurs. It has a unique shape and chemical properties.
6. The product is the substance or substances formed as a result of the chemical reaction catalyzed by the enzyme. The substrate is converted into the product(s) at the active site.

Answer:

1. Protein
2. The minimum energy for a reaction to start
3. Enzyme's active site has a specific shape for a particular substrate
4. Reactant molecule on which enzyme acts
5. Region on enzyme where substrate binds and reaction occurs
6. Substance(s) formed by the enzyme - catalyzed reaction
