final Flashcards
why can’t humans digest cellulose (dietary fiber) for energy?
we don’t have the enzymes to digest it
what do you need to digest starch?
amylase
what do humans use first for energy?
glucose
what happened in test tube 3 (physio ex page 2)
amylase broke down starch down into simple sugars
Why didn’t test tube 1 break down the starch?
heating denatured the enzyme
what stomach cells are needed to release protein?
pepsinogen and hydrochloric acid
yields the pepsin enzyme
what does pepsin need to work?
an acidic environment
why did test tube 2 work better than any of the other test tubes (physio ex page 4)
it has a pH of 2
why didn’t test tube one work (physioex page 4)?
the test tube was heated
why does pH go down when fat is digesting?
fat is made up of fatty acids
why did the first test tube digest fat the best (page 5)?
it had the greatest decrease in pH and had bile salts
what is the term for when bile and oil are together?
emulsification
how do you calculate net filtration pressure?
GHP - (COP+CHP)= NFP
what are the layers of the filtration membrane (deep to superficial)?
glomerular capillary endothelial cells
basil lamina
podocytes
