Question

1. describe the effects that enzymes can have on substrates.

Explanation:

Enzymes are biological catalysts. They lower the activation - energy required for a chemical reaction involving substrates, thus increasing the reaction rate. They are highly specific to certain substrates and can also regulate metabolic pathways.

Answer:

Enzymes lower the activation energy of reactions involving substrates, increasing the reaction rate. They are substrate - specific and can regulate metabolic processes.
