Breaks down starch into sugars

AmylaseTrue for …

Starch is a carbohydrate. Amylase is the enzyme which breaks it down to make simple sugars like

glucose

Generally work best at 37oC

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

AmylaseTrue 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
