digestion Flashcards
def tissue
a group of cells with similar structure and function
def an organ
a group of different tissues that perform a specific function together
def organ system
a group of organs that work together
def digestive system
organ system in which several organs work together to digest and absorb food
def enzymes
biological catalysts with a specific active site that speed up reactions
def what enzymes do
substrate fits into active site
bind together
quick
products released
what effect does temp have on enzyme activity
increases rate of reaction
at optium fast as possible
after begin to denature
def how enzymes are denatured by temp
high temp causes protien chains to unravel and change shape of active site
def why enzymes have an optium ph
forces holding the protien chains in position are effected by ph
change in ph change in active site
where is amylase
salivary glands small intestine pancreas
def function amylase
break doen starch to glucose
where is protease made
stomach small intestine pancreas
def function protease
break down protien to amino acids
where is lipase made
pancreas and small intestine
