2. Flash Card 13 ATP  Adenosine Triphosphate
A ribonucleotide found in RNA.
ATP is used as a energy storage molecule and is considered the energy currency of cellular metabolism in the cell

3. Flash Card 14
substrate
The reactants in an enzyme catalyzed reaction.

4. Flash Card 15
The region of an enzyme surface to which a specific set of substrates binds, lowering the activation required for a chemical reaction to occur.
active site

5. Flash Card 16 allosteric site
A part of an enzyme, away from the active site, that serves as an on off switch for the function of an enzyme.
When the allosteric modulator is bound to the enzyme it causes a change in the enzymes structure.

6. Flash Card 17 allosteric inhibitor
A allosteric modulator (molecule) that when bound to the enzyme leads to inactivation of the enzyme.

7. Flash Card 18
The sum total of chemical reactions in a cell. Catabolism are the reactions in which larger molecules and polymers are broken into several molecules typically releasing energy which anabolism are those reactions in which smaller molecules are combined to make larger molecules including polymers.
metabolism

8. Flash Card 19 metabolic pathway
Is a series of chemical reactions in a cell leading to the production or degradation of a molecule. Each reaction has its own specific enzyme.
Molecules are built and broken down in a series of chemical reaction steps.

9. Flash Card 20 feedback inhibition
A control mechanism in a metabolic pathways in which the product is an allosteric modulator that inhibits the enzyme that catalyzes the first chemical reaction the pathway
