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
Why are enzymes necessary?
to act as a catalyst bin chemical reactions
