Enzymes and digestive system test 2 Flashcards
what are enzymes
helper protein molecules for chemical reactions
what is synthesis
building molecules
what is digestion
breaking down molecules
what do all chemical reactions require
an enzyme
what are catalysts
enzymes that increase the rate of reaction
what biomolecules are enzymes
proteins
each enzyme is a specific what
helper to specific reaction
enzymes require a certain what for the job
the right shape
what breaks down sucrose
sucrase
what breaks down proteins
proteases, trypsin, chymotrypsin, pepsin
what breaks down fats and lipids
bile and lipase
what enzyme builds dna
dna polymerase
how do reactions affect enzymes
thye are not changed
what amount of enzyme is needed for a reaction
very little
what is the active site
where enzyme and substrait connect
why is the shape of the protein important
allows enzyme and protein to click
what is a substrait
molecule that enzymes work on
what is the product
what the enzymes help produce from the reaction
what affects protein structure
the order of amino acids
what happens if order of amino acids is wrong
it has the wrong shape and cant do its job
what an optimum temp
temp with greatest number of collisions between enzyme and substrait
what is the optimum temp for human enzymes
37 degrees
what happens when the temperature reaches boiling for enzymes
protein denatures, unfolds and loses shape
what happens when the temperature gets too low for enzymes
molecules move slower and there are fewer collisions
what do changes in pH change
protein shape
what is the pH of most human enzymes
6 to 8
what is the most important thing for enzymes
shape
what do animals make energy with
food and oxygen
what is ATP used for
synthesis
what are the steps of getting and using food
ingest digest absorb eliminate
what is ingest
taking in food
what is digest mechanical and chemical digestions diffrences
mechanical is physical digestions and chemical is breaking food down with chemicals
