100
Law that states that energy cannot be created or destroyed, only changed.
What is the Law of Thermodynamics?
100
The building of molecules.
What is Anabolism?
100
As temperature increases, enzyme activity _____.
What is increases?
100

The reactant on which an enzyme works.

What is a substrate?

100

Inhibitor does not bind to the active and causes active site to change shape.

What is Noncompetitive Inhibition?

200
The relative amount of disorganization.
What is entropy?
200
The breaking down of molecules.
What is Catabolism?
200
Enzymes may _____ at high temperatures.
What is denatures?
200

The specific region of an enzyme that binds the substrate and that forms the pocket in which catalysis occurs.

What is the active site?

200

Area on an enzume away from the active site.

What is the allosteric site?

300

Supplies a constant supply of energy for living things.

What is the Sun?

300
The sum of all the chemical reactions that occur in a cell.
What is Metabolism?
300
Occurs when enzymes can not bind its substrate.
What is inhibition?
300

Organic cofactors

What are coenzymes?

300

Binds in a way that stabilizes the active form

What is an allosteric activator?

400

Every energy transformation increases entropy

What is the second law of thermodynamics?

400
Spontaneous reaction that releases energy.
What is Exergonic?
400

The form of energy the cell is able to use

What is ATP (free energy)?

400

The initial energy investment necessary to start a reaction and makes the chemical bonds in molecules unstable.

activation energy

400
Binds in a way that stabilizes inactive form

What is an allosteric inhibitor?

500

A particular reaction has a ΔG of +30.5 kilojoules/mol. Is this reaction spontaneous?

No, it is not spontaneous, because it is endergonic.

500
Reaction that requires the input of energy.
What is Endergonic?
500

After a substrate binds to an enzyme, the enzyme alters its shape slightly causing a tighter fit. This is called?

induced fit

500

The ability of an enzyme to select a specific substrate from a range of chemically similar compounds

What is enzyme specificity?

500

A method of metabolic control in which the end product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway.

What is feedback inhibition?
