what is diffusion
when water crosses the cell membrane
the process where vesicles transport particles to the edge of the cell membrane and deposits its contents outside the wall
a substance moves from a solution with a low concentration to a solution with high concentration
a substance moves from a solution with high concentration to a solution with low concentration
What is osmosis
when water crosses the cell membrane
a substance moves from a solution with a low concentration to a solution with high concentration
the process where vesicles transport particles to the edge of the cell membrane and deposits its contents outside the wall
a substance moves from a solution with high concentration to a solution with low concentration
when your body makes big chemicals, they leave the cell by
(a)
In our lab with glucose, starch, and iodine, which could pass through the membrane? What process allowed it to pass through the membrane?
Glucose- it was the smallest substance, diffusion
Glucose- it was the biggest substance, diffusion
Iodine- it was the smallest substance,diffusion
Starch- it was absorbed into the cell membrane, diffusion

a substrate is (a)
a reactant is (a)
a product is the (a)
activation energy is (a)
how do enzymes affect activation energy in a reaction
they speed up the process of the reaction
they slow down the process of the reaction
they lower activation energy
they permanently change the activation site
which line is the activation energy without the enzyme
A
B
what environmental factors affect enzymes
teperature
ph
environmental factors don't affect enzyme activiy
macromolecule
the diffusion of a fluid such as water across a membrane the equalize the concentration of solution on either side of membrane
lipid with a phosphate head attached to two long lipid tails
a large biological molecule, made if one or more subunits linked together
a model of a biological membrane structure and function that the ability of embedded proteins to move laterally within the membrane bilayers
draw a phospholipid
semipermeable (a)
why is it important for the cell membrane to be fluid?
in order to maintain homeostasis (stable internal conditions) by controlling what leaves and enters
so it can allow all things through
to be able to move freely around your body
what are the main components of the cell membrane
phospholipids
proteins
oyxgen
glucose
what would a cell do if the concentration outside of the cell is 10% sugar and 90% h2o, and the concentration inside of the cell is 80% sugar and 20% h2o
the cell would swell because the concentration of water is higher outside of the cell and water moves from higher to lower
the cell would shrink because the concentration of water is higher outside of the cell and water moves from lower to high
the cell would stay the same because the concentration of water is higher outside of the cell and water doesn't move
what would a cell do if the concentration on the outside of the cell was 50% water ad 50% sugar, and the inside of the cell was 50% water and 50% sugar
the water would move into the cell causing it to swell because they have equal concentration
the water would move out of the cell causing it to shrink because they have the same concentration
water wouldn't move because they have the same concentration which means the cell would stay the same
water would move out of the cell so the concentration on the outside of the cell would be higher
what would a cell do if the concentration on the outside of the membrane 49% sugar and 51% water, and the concentration on the inside of the cell was 25% sugar and 75% water
the cell would swell because water moves from lower concentration to higher concentration
the cell would shrink because water moves from higher concentration to lower concentration
the cell wouldn't change because the concentration on the inside of the membrane is higher
