Enzymes

The sum of all biochemical reactions in a cell is known as…

Metabolism

Catabolism

Breaks complex compounds into simpler components

Anabolism

Simpler materials assembled to make complex materials

What is ATP’s full name?

Adenosine triphosphate

Enzymes

Catalyze reactions by lowering activation energy

When an enzyme is denatured, what happens?

Loses its function

Where does a substrate bind on an enzyme?

Active site

Where does a cofactor bind on an enzyme?

Allosteric site

What happens during competitive inhibition?

A substrate can fill an enzyme’s active site

During competitive inhibition, what happens when the correct substrate fills an enzyme’s active site?

It becomes activated and produces products

During competitive inhibition, what happens when the incorrect substrate fills an enzyme’s active site?

Nothing happens

A factor that determines competitive inhibition is the amount of correct and incorrect substrate present is also known as…

concentration

A factor that determines competitive inhibition is the distance of a substrate in comparison to the active site is also known as…

proximity

In noncompetitive inhibition, enzymes have…

an active site and allosteric site

An additional molecule to substrate required for a reaction to proceed is called a…

cofactor

During noncompetitive inhibition with an activator, an enzyme begins…

inactivated

During noncompetitive inhibition with an activator, when a cofactor fills the allosteric site, what happens?

The active site changes shape

During noncompetitive inhibition with an inhibitor, the enzyme begins…

activated

During noncompetitive inhibition with an inhibitor, when an inhibitor binds to the allosteric site, what happens?

The active site changes shape

An enzyme process that has a produce or intermediate later in a pathway inhibits a step earlier in a pathway is known as a…

Feedback inhibition / feedback regulation

Feedback inhibition can include what enzyme mechanisms?

Competitive and noncompetitive with an inhibitor

Why can’t noncompetitive with activators be present within feedback inhibition?

An activator cannot inhibit an enzyme
