enzymes (nat5 recap)

Question 1

what factors might affect the rate of enzyme activity?

Answer 1

1) temperature
2) pH
3) substrate concentration
4) enzyme concentration
5) product concentration
6) inhibitors

Question 2

how do enzymes work?

Answer 2

enzymes specific to each substrate based on shape of active site. lock and key hypothesis. complimentary shape.

Question 3

enzyme catalyst?

Answer 3

speed up chemical reactions, essential for life. biological catalyst = enzymes

Question 4

optimum conditions?

Answer 4

the condition which allows enzymes to work at their highest rate. e.g. temperature and pH

Question 5

chemical reactions?

Answer 5

synthesis- builds up
degradation- breaksdown

Question 6

energy required? (activation energy)

Answer 6

enzymes lower the energy required to start a reaction

Question 7

active site?

Answer 7

on an enzyme - site where an enzyme binds with its substrate

Question 8

starting molecule called?

Answer 8

substrate
