proteins - their functions and uses Flashcards
where are digestive enzymes produced
by specialised cells in the lining of the gut
what is the general function of digestive enzymes
they break down large molecules into smaller molecules
where is the enzyme amylase produced
in the salivary glands, the pancreas and the small intestine
what does amylase do
it speed up the breakdown of starch into sugars in the mouth and small intestine
where is the enzyme protease produced
in the stomach, the pancreas and small intestine
what does protease do
it catalyses the breakdown of proteins into amino acids in the stomach and small intestine
where is the enzyme lipase produces
in the pancreas and small intestine
what does lipase do
it breaks down lipids into fatty acids and glycerol in the small intestine
what conditions do the enzyme in the stomach work best in
acidic (1-6)
approximately, what is the pH of the acid in the stomach
pH 2
where is “bile” produced
the liver
what does bile do
it acts in the small intestine to neutralise the acid from the stomach
do enzymes in the small intestine prefer alkaline or acidic conditions
alkaline (this is why it neutralises the acid and makes it slightly alkaline)
name three processes where enzymes work inside cells
enzymes in respiration
photosynthesis
protein synthesis
