Flashcards in Lecture 8 Deck (17):
1

Active site

The region of an enzyme were substrate molecules bind and undergo chemical reaction

2

Allosteric site

Regulation of a protein by binding effect or molecule the site other than the proteins active site

3

Anabolic pathway

Controlled series of reactions in which smaller lower energy less complex molecules are built up into larger hiring a G and more complex molecules

4

Catabolic pathway

Metabolic pathways that breakdown molecules into smaller units that are either oxidize to release energy or used another anabolic reactions

5

Catalyst

A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change

6

Competitive inhibitor

A form of enzyme inhibition for binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa

7

Energy

The strength and vitality required for sustained physical or mental activity

8

Entropy

Thermodynamic quantity representing the unavailability of the systems thermal energy for conversion into mechanic work

9

Exergonic reactions

A reaction to loses energy during the process of the reaction

10

Feedback inhibition

An enzyme inhibitor is a molecule that binds to an enzyme and decrease activity

11

First law of thermodynamics

The total energy of an isolated system is constant

12

Kinetic energy

The energy that he possesses due to its motion

13

Metabolism

I'll chemical reactions involve in maintaining the living state of sales and the organism

14

Noncompetitive inhibitor

Binds to the enzyme away from the active site

15

Potential energy

The energy that an object has due to its position in a force field

16

Substrate

The substance in which an enzyme acts

17

Activation energy

Minimum energy which must be available to a chemical system with potential reactions to result in a chemical reaction
