enzymes Flashcards
what is the substrate molecule for amylase, protease and lipase?
lipase-lipids/fats
amylase-starch
protease-proteins
what are the products when the enzymes amylase, lipase, and protease chemically breakk down their substrate?
amylase-sugars
protease-amino acids
lipase-fatty acids and glycerol
where is amylase made?
amylase is be made in the salivary glands, pancreas and small intestine
where is protease made?
protease is made in the stomach, pancreas and small intestine
where is lipase made?
lipase is made in the pancreas and the small intestine
where do lipase amylase and protease work?
amylase works in the mouth and the small intestine
protease works in the stomach and the small intestine
lipase works in the small intestine
what do enzymes do?
speed up chemical reactions
what factors affect the rate of enzyme activity and denature it?
-pH
-temperature
what are enzymes?
enzymes are biological catalysts that speed up the rate of chemical reactions in living organisms
what is the active site?
the active site of an enzyme is where another molecule (substrate) can fit during a reaction
the shape of the active site must be complemetary to the substratelike a lock and key
what are enzymes made from?
enzymes are made of proteins which are made of long chains of amino acids
what pH do enzymes in the stomach workk best at?
2
what role does bile play in physically breaking down large food molecules?
bile can physically breakk down lipid globules into smaller globules. This process is called emulsification.
This helps because it increase the surface area for lipase to digest. Bile is also alkaline so helps to neutralize the acidity entering the small intestine which is good because small intestine enzymes workk best at this pH.
BILE IS NOT AN ENZYME
