1

Protein function depends on their...

Shape

2

Changes to the protein shape result in...

they can't do their job
they won't function properly

3

Denaturing

making protein unable to do its job

4

enzymes

protein catalysts

5

catalysts

accelerate reactions
make them happen faster

6

Substrate

fits into an active site

7

shape affects...

function and apperance

8

enzyme reactions tend to happen faster at...

higher temperatures

9

Enzyme Regulation - On

Activation
make it work

10

Enzyme Regulation - Off

Inhibition
keep it from working

11

Competitive Inhibition

two molecules can occupy the same active site

12

Allosteric

somewhere other than the active site

13

Noncompetitive

inhibitor does not 'compete' for the active site

14

Phosphotylation

activation by adding phosphate

15

Feedback Loop

products of a reaction influence whether further products are made

16

Negative Feedback Loop

product inhibits further reactions
