Enzymes Flashcards
What are enzymes
Natural catalysts
Biological catalysts
What are enzymes made of
Proteins
Each enzyme has a unique…
Shape
The enzymes unique shape allows it to
Fit onto the substance it reacts with
What happens when the temperature increases to much for an enzyme
It becomes denatured
What PH. Does pepsin work best at
Ph 2 although must enzymes work best at PH7
Amylase coverts … Into…
Starch into sugar
Where is amalyase produced
Salivary gland
Pancreas
Small intestine
….coverts protein into ….
Protease
Amino acids
Where is protease found
Stomach
Pancreas
Small intestine
…coverts …. Into glycerol and….
Lipase
Lipids
Fatty acids
Where is lipase found
Pancreas
Small intestine
What is the propose of bile
To neutralise stomach acid
Where is bile stored and where is it made
Made in liver
Stored in gall bladder
Other than the neutralisation of stomach acid what is the other use of bile
To emulsify fats giving them a larger surface area allowing digestion to occur quicker
What is the stomachs role in digestion
Pummels the food with the muscular walls
Produces protease
Produces hydrochloric acid to kill bacteria and make the right ph for protease
What is the role of the small intestine in the digestive system
Produces protease and amylase and lipase
Absorbs divested food
What does the pancreas do in digestion
Produces protease amylase and lipase
What is the role of the large intestine in the digestive system
Excess water is re absorbed
What is respiration
The breaking down of glucose causing the release of energy going into every cell
