biological molecules

Question 1

what’s the induced fit model?☁️

Answer 1

shape of active site changes slightly to enable e-s complexes to form

Question 2

5 factors that affect the rate of enzyme controlled reactions?😻

Answer 2

enzyme conc
substrate conc
conc of inhibitors
pH
temperature

Question 3

what are competitive inhibitors?🩷

Answer 3

bind to the active site
increasing substrate concentration decreases their effect

Question 4

what are non-competitive inhibitors?💕

Answer 4

bind at allosteric binding site
increasing substrate concentration has not impact on their effect

Question 5

2 starch and glycogen adaptations?🌋

Answer 5

-branched- large SA for enzymes to act in and break down quickly
-insoluble- no affect on osmosis

Question 6

what are the molecules that make up triglycerides?
what are their amounts?
what bond?
🎀💞🩷🌷💐

Answer 6

Question 7

what are the molecules that make up phospholipids?
what are their amounts?
what bond?
😸🌼🌻⭐️😽😋

Answer 7

phosphate group, glycerol, 2 fatty acids
ester bond

Question 8

test for protein?💓

Answer 8

biuret
sodium hydroxide
dilute copper (II) sulfate
blue to purple

Question 9

5 features of water?💦

Answer 9

-important metabolite
-high latent heat capacity (vaporisation)
-can resist changes in temperature
-good solvent
-strong cohesion between molecules
