1 of 22
what are the 2 types of digestion
physical digestion and chemical digestion
2 of 22

digest carbohydrates
3 of 22
what do the enzymes proteases do
digest proteins
4 of 22
what do enzymes lipases do
digest lipids
5 of 22

bloating ,nausea,diarrhoea and cramps
14 of 22
what is hydrolysis
adding water to a glycosidic bond in carbs or peptide bond in proteins
15 of 22
three type of bonds in proteins
disulfide bonds,ionic bonds,hydrogen bonds
16 of 22
what is the active site
the site in which the substrate the enzyme breaks down fits
17 of 22
what is the lock and key model
where one enzyme has one substrate
18 of 22
what do enzymes do
lower activation energy
19 of 22
what does the induced fit model state
that the enzyme can be used on substrates that are the same or very simluar to the active site
20 of 22
what things effect enzymes
temperature,ph,substrate concentration
21 of 22
what are inhibitors
they attach themselves to the enzyme either in the active site (competive)and other site on the enzyme (non competative)
