• is it an enzyme?
• organ that produces it?
• organ where it is active?
• Function?

Answer 4

• is it an enzyme? Yes
• organ that produces it? Stomach
• organ where it is active? Stomach
• Function? Digests Protein

Question 5

Pancreatic lipase

• is it an enzyme?
• organ that produces it?
• organ where it is active?
• Function?

Answer 5

• is it an enzyme? Yes
• organ that produces it? Pancreas
• organ where it is active? Small Intestine (duodenum)
• Function? Digests Lipids

Question 6

Bile Salts

• is it an enzyme?
• organ that produces it?
• organ where it is active?
• Function?

Answer 6

• is it an enzyme? No
• organ that produces it? Liver
• organ where it is active? Small Intestine
• Function? Emulsify fats and break it down into small particles. Helps with the absorption of fat in the gut

Question 7

Why is pepsin most effective in the organ where it is active?

Answer 7

Our stomach secrete gastric juice containing many different acid. One of the acids is hyrdochloric aicd which is very acidic with a pH scale between 1 to 3, so pepsin will be more effective where there’s an area of high acid concentration which would be the stomach

Question 8

Is water necessary for digestion?

Answer 8

Yes, water is necessary to make hydrochloric acid. Majority of pancreatic juice is made up of water. Water is important for hydrolysis to take place which is the break down of food molecules.
