1.5

An enzyme is a

biological catalyst

A substance which accelerates any chemical reaction but is not consumed by the reaction is called a:

catalyst

Often enzymes require a ___________ in order to function as a catalyst.

cofactor

An organism can live without enzymes. true or false.

false

Substrate

involved in a chemical reaction and is chemically changed by the reaction.

Condition s in which enzymes are most active are described as

optimal

cofactor

plays an important role in activating that enzyme

The substance bon which the enzyme acts is called the

substrate chemical

active site

the region where the substrate molecules binds and reacts with the enzyme.

If the reactants found in a cell are removed from the cell how will they behave chemically?

they may not be able to react
