Question

what occurs during substrate binding? the reaction releases the product formed. there activation energy needed increases. the enzyme - substrate complex is formed. the enzyme goes through denaturation.

Explanation:

Enzymes are biological catalysts. When a substrate binds to an enzyme, an enzyme - substrate complex is formed. The reaction releasing the product occurs later in the enzymatic reaction process. Enzymes lower activation energy, not increase it. Denaturation is the loss of an enzyme's structure due to factors like high temperature or extreme pH, not related to substrate binding.

Answer:

The enzyme - substrate complex is formed.
