Question 2

This type of process builds polymers

Answer 2

Anabolic

Question 3

This type of process involves the breaking down of polymers into their monomers

Answer 3

Catabolic

Question 4

Refers to the study of energy and energy transfer involving physical matter

Answer 4

Thermodynamics

Question 5

The energy transferred from one system to another that is not work

Answer 5

Heat energy

Question 6

Energy associated with objects in motion

Answer 6

Kinetic energy

Question 7

Energy that could be transferred into kinetic energy, but it is stored

Answer 7

Potential energy

Question 8

Negative charge in free energy and consequently release free energy

Answer 8

Exergonic reactions

Question 9

In these reactions the products have more free energy than the reactants

Answer 9

Endergonic reactions

Question 10

Molecules that catalyze chemical reactions

Answer 10

Enzymes

Question 11

The chemical reactants to which an enzyme binds

Answer 11

Substrates

Question 12

The location within the enzyme where the substrate binds

Answer 12

Active site

Question 13

When an inhibitor molecule competes with the substrate for binding to the active site

Answer 13

Competitive inhibition

Question 14

When an inhibitor molecule blocks substrate binding, doing it from allosteric site

Answer 14

Noncompetitive inhibition

Question 15

When an inhibitor molecule induces a conformational change that reduces the affinity of the enzyme for its substrate

Answer 15

Allosteric inhibition

Question 16

Involves the use of a reaction product to regulate its own further production

Answer 16

Feedback inhibition
