Breaks down starch into sugars Amylase True for … Starch is a carbohydrate. Amylase is the enzyme which breaks it down to make simple sugars like glucose

Generally work best at 37 o C True for … All of them This is body temperature and digestive enzymes work best at this temperature

Produces amino acids True for … Protease Protease is the enzyme for proteins and you get amino acids when proteins are broken up

Act as a catalyst to help digest food True for … All of them A catalyst speeds up a chemical reaction without being part of the actual reaction. This is in effect a definition of a digestive enzyme

Works best in low pH ( acid conditions) True for … Protease Protease is produced in the stomach which is acidic. Most proteins are broken down here.

Break down large particles into smaller ones True for … All of them This is in effect a definition of digestion. All enzymes help this to happen

Helps change fats into fatty acids and glycerol True for … Lipase Lipase is the enzyme which works for fats. Fats are large molecules, made up of the smaller particles called fatty acids and glycerol

Can change shape at high temperatures True for … All of them The enzyme no longer works because the “lock and key” do not match. This change of shape is also called being “denatured”.

Made of proteins folded into a special shape True for … All of them Digestive enzymes are in fact proteins. A bit confusing ! The special shape makes the “lock and key” match

Help to make glucose available in the blood stream Amylase True for … Glucose is produced when starch is broken down by amylase during digestion. It must pass into the bloodstream so it is available for respiration
