Catalase Sources - plant tissues e.g. potato tuber, apple animal tissues e.g. liver, muscle hydrogen peroxide ---------- water + oxygen Speed up the break down of hydrogen
peroxide to water and oxgen
Importance of catalase
Hydrogen peroxide is a toxic metabolic by-product produced in metabolic reactions. It is harmful when accumulated to high concentration. Catalase can speed up the breakdown of hydrogen peroxide to water and oxygen. So it help the removal of toxic hydrogen peroxide.
Amylase
Source – saliva, germinating seeds / seedlings, yeast culture Starch + water --------------- maltose Amylase speeds up the hydrolysis /
digestion of starch to maltose. Importance – to digest starch to maltose
Invertase (sucrase)
Source – yeasts, bacteria, intestinal juice
Sucrose + water - fructose + glucose Invertase speeds up the hydrolysis of sucrose
to fructose and glucose. Importance – It helps the digestion of sucrose to simple sugar
Pepsin
Source – gastric juice Protein + water ----- polypeptides Pepsin speeds up the hydrolysis of
protein to peptides. Importance – It helps the digestion of
protein to polypeptides
Trypsin Source – pancreatic juice polypeptide + water -- peptides Trypsin speeds up the hydrolysis of
polypeptide to peptides Importance – It helps the digestion of
polypeptide to peptides
maltase
Source – intestinal juice maltose + water glucose Maltose speeds up the hydrolysis of
maltose to glucose Importance – It helps the digestion of
maltose to glucose
Urease
Bacteria, liver ammonia + carbon --- urea dioxide Urea speeds up the formation of urea
from ammonia and carbon dioxide. Urease helps the formation of urea in
deamination of excess amino acids.
