What are enzymes? What do they do?
Enzymes are catalysts produced by living things. They speed up chemical reactions in the body so that they take place at an efficient rate. Without enzymes, we would die.
What happens to an enzyme when the temperature gets too much higher than the optinum?
The enzyme denatures
What happens to an enzyme when the pH gets too much higher than the optinum?
The enzyme denatures
What happens to the enzyme when it denatures?
The active site changes shape/size and a reaction can no longer take place as the substrate will not fit in anymore.
Why can’t a reaction take place when an enzyme is denatured?
As the active site is no longer the specific shape/size that it needs to be, the substrate no longer fits in.
Why do digestive enzymes need to break down large food molecules?
So that the smaller, soluble molecules can pass easily through the walls of the digestive system, alowing then to be absorbed into the bloodstream.
what is the substrate that goes into a protease enzyme?
Protein
what is the product that comes out of a protease enzyme?
Amino acids
Where are protease produced?
Stomach, small intestine and pancreas
what is the substrate that goes into a lipase enzyme?
Lipids
what is the product that comes out of a lipase enzyme?
Glycerol and fatty acids
Where are lipase enzymes produced?
Small intestine and pancreas
what is the substrate that goes into a amylase enzyme?
Starch
what is the product that comes out of a amylase enzyme?
Sugars eg. maltose and dextrins
where are amylase enzymes produces?
Small intestine, pancreas and salivary glands
