Chapter 5- Cellular Chemistry Flashcards
1
Q
Energy
A
capacity to do work
2
Q
Metabolism
A
sum of all chemical reactions in the body (build up + break down)
3
Q
Collision theory
A
molecules must collide with enough force in the correct orientation for a reaction to occur
4
Q
Activation energy
A
the amount of energy required to start a chemical reaction
5
Q
Induced fit model
A
enzymes are flexible structures that conform around a recognizable substrate; opposite the Lock and Key model
6
Q
Competitive inhibitors
A
molecules that actively compete for the enzymes active site
7
Q
NonCompetitive inhibitors
A
molecules that bind elsewhere on the enzyme, rendering it inert
8
Q
Denature
A
render inactive
9
Q
Saturation
A
all enzymes are bound and engaged in the reaction; max, speed has been reached
