enzyme that breaks down starch into sugars
found in saliva and pancreatic juices

Question 5

alcohol dehydrogenase

Answer 5

metabolism
enzyme that helps to metabolise ethanol

Question 6

1cza hexokinase

Answer 6

metabolism
enzyme that adds a phosphate to glucose after glucose is taken up by the cell

Question 7

haemoglobin

Answer 7

oxygen transport and metabolism
binds oxygen in the lungs and carries it in the blood to tissues for use in metabolism

Question 8

ATP synthase

Answer 8

metabolism and energetics
membrane protein that generates ATP for use in cellular functions

Question 9

Antibody

Answer 9

immune protection
bind to cellular invaders like bacteria and viruses to help protect the body from infection
