Cell A produces proteins. Cell B
synthesizes steroids. What differences
would be expected in these two cells? -
ANSWER-Cell A would have more rough
endoplasmic reticulum than cell B.
What is nervous tissue? - ANSWER--found
in brain, spinal cord, and nerves
-composed of neurons and neuroglia
What is osmolality of normal blood plasma?
- ANSWER-300 mOsm
What is osmolality? - ANSWER--unit of
concentration that gives the total molality of
all solutes is the osmolality of the solution.
,-water moves from lower to higher
osmolality
What is osmosis and its requirements? -
ANSWER--added by channel called
aquaporins
-required: must be a solute concentration
diff across membrane and membrane must
be less permeable to solute than to water
What is osmotic pressure? - ANSWER--
force surrounding a cell required to stop
osmosis.
-A higher solute concentration would
require a higher osmotic pressure.
tendency of solution to take in water by
osmosis
