Flashcards in Bio enzyme Deck (24):
1

more complex

increases in G (free energy), more likely to fall apart

2

enzymes has ATP attached to it

the phosphate attaches to the substrate,

3

entropy

describes level of disorder

4

energy coupling

transfer of energy catabolism to anabolism

5

energy released in an reaction

is stored in bonds

6

38 ADP + 38P

38ATP

7

exergenic

catabolic
spontaneous
down

8

endergonic

anabolic
non-spontanous
up

9

cofactor

molecules that activate enzymes, at the active site with the substrate
ex. iron

10

increase enzyme concentration

increase rxn rate

11

increase of substrate

increase rxn rate until leveling out
max velocity, highest point

12

competitive enzyme inhibitor

block active site, not permanent

13

noncompetitive enzyme inhibitor

changes of shape of active sites, nonpermanent. binds at allosteric site

14

how to overcome activation energy

heat
enzyme

15

How does enzyme facilitate rxn to fall apart

-increase in complexity
- apply breaker

16

enzyme decrease energy input

add phosphate group to increase complexity and break it down faster

17

exogonic ex.

atp break down

18

endergonic ex.

protein synthesis
DNA replication

19

how enzyme lower Ea in endergonic

-align molecule
-stretch molecule (separation

20

enzyme specificity

enzyme only interact with specific substrate that has complimentary (opposite) charge and shape

21

induced fit model

decribes how enzyme binds/surrounds a substrate

22

allosteric regulation

only in quaternary

23

metabolic pathway

unnecessary molecules are made (3) until the 4th (needed) molecule is produced. 3 enzyme used.

24

Feedback inhibition

increase in 4th molecule, needs to lowe. stop production by using it to competive inhibit the first enzyme
