- Enzymes
- shape
- vital for function
- High temperatures change the shape
- vital for function
- PH Values
- Different enzymes work best at different Ph
- Stomach produces hydrochloric acid
- works most effectively at acid conditions
- Liver produces Bile
- stored in gall bladder before being released into small intestine
- Bile neutralizes the acid that was added to the food by the stomach
- Provides ALKALINE conditions so enzymes work effectively
- Bile neutralizes the acid that was added to the food by the stomach
- stored in gall bladder before being released into small intestine
- Some work outside body cells
- Digestive emzymes
- Produced by cells in glands and in lining of gut
- enymes pass out of cells into the gut.
- Catalyse the breakdown of large molecules into smaller ones
- enymes pass out of cells into the gut.
- Produced by cells in glands and in lining of gut
- Digestive emzymes
- Amylase
- produced in salivary glands pancreas and small intestine
- Breaks down Starch to suger
- in mouth and small intestine
- Breaks down Starch to suger
- produced in salivary glands pancreas and small intestine
- Protease
- produced by stomach pancreas and small intestine
- Breaks down Proteins to amino acids
- in stomach and small intestine
- Breaks down Proteins to amino acids
- produced by stomach pancreas and small intestine
- Lipase
- produced by pancreas and small intestine
- Catalyse the breakdown of lipids (fats and oils) into fatty acid and glycerol
- in small intestine
- Catalyse the breakdown of lipids (fats and oils) into fatty acid and glycerol
- produced by pancreas and small intestine
- Some microorganisms produce enzymes that pass out of the cells
- Used in home
- biological detergents
- may contain protein digesting and fat digesting enzymes
- more effective at low temperatures than other detergents
- biological detergents
- Used in Industry
- proteases
- pre-digest protein in baby foods
- carbohydrases
- convert starch into sugar syrup
- eg sport drinks
- convert starch into sugar syrup
- Isomerase
- convert glucose syrup to fructose syrup
- much sweeter so can be used in smaller quantities in slimming products
- convert glucose syrup to fructose syrup
- enzymes bring out reactions at normal temperatures and pressures that would otherwise require expensive, energy demanding equipment
- most enzymes are denatured at high temperatures and are costly to produce
- proteases
- Used in home
- shape
