B5 enzymes Flashcards
(28 cards)
what are enzymes?
proteins that speed up chemical reactions in living things
what are enzymes made up of
enzymes are made up of proteins
what is a catalyst
a catalyst is a substance which increases the rate of reaction without being changed or used up in a reaction
why is the shape of an enzyme important
it allows the enzyme to bind to substrates,
at which temperature does enzyme work best in animal
37°C
why do enzymes stop working at high temperatures
Higher temperatures disrupt the shape of the active site
why do enzymes affect the rate of reaction
lower the activation energy of a reaction
what is the name of the substrate to which the enzymes attaches
substrate
at which temp does enzyme work best in human
37∘C.
What is optimum temp
The temperature that works best for a procedure
what does protein get broken down into
amino acids
stomach pH level
2
what does lipase break down
trygliceride into glycerol
what does amylase break down
starch into maltose
bile emulsifies what
fats
what body part absorb most water
small intestine/ileum
what body part produces bile and where is it stored
produced in liver and stored in gall bladder
duodenum
stomach to small intestne
ileum
small intestine
colon
large intestine
why are some enzyme not ctive in the stomach
this isbecause the ph level is high
pepsin break down
protein into pepside
where is protease made in the body
pancreas,stomach ,small intestine
where is lipase made in the body
pancreas
