one point four: proteins and enzymes

Question 1

why is there are variety in protein?

Answer 1

different amino acid sequences

Question 2

name five protein functions

Answer 2

structural, enzymes, hormones, antibodies, receptors

Question 3

what are enzymes?

Answer 3

biological catalysts which are made by all living cells

Question 4

what do enzymes do?

Answer 4

speed up cellular reactions

Question 5

what does enzyme action result in?

Answer 5

products(s)

Question 6

what are the two kinds of enzyme reactions?

Answer 6

degradation and synthesis

Question 7

when are enzymes most reactive?

Answer 7

in optimum conditions

Question 8

what are enzymes affected by?

Answer 8

ph and temperature

Question 9

what happens when an enzyme is denatured?

Answer 9

changes shape which affects reactions rate

Question 10

what are proteins made of?

Answer 10

carbon, hydrogen, oxygen, nitrogen

Question 11

what are hormones?

Answer 11

carry chemical information through blood

Question 12

what do antibodies do?

Answer 12

provide immunity against pathogens

Question 13

why are enzymes specific?

Answer 13

has an active site and only one substrate can fit in it

Question 14

what is a substrate?

Answer 14

substance enzyme acts upon

Question 15

what is a degradation reaction

Answer 15

‘breaking down’ reaction

Question 16

what is a synthesis reaction?

Answer 16

‘building up’ reaction

Question 17

what does it mean if an enzyme is denatured?

Answer 17

active site changes meaning the substrate can no longer fit resulting in decrease in enzyme activity
