lesson 18 active transport Flashcards
what does active transport do
it moves substances from a more dilute solution to a more concentration solution
the main process of active transport is essentially against the what
against the concentration gradient
active transport requires energy from where
respiration
in diffusion particles move down the concentration gradient where as active transport is where…
particles are moved against the concentration gradient
diffusion does not require energy from respiration however active transport..
does require energy from respiration
the cavity of the small intestine, where the food is digested is called the what
the lumen
in the lumen we find what
the molecules produced when food is digested, a good example is sugars such as glucose
root hair cells transport ions such as magnesium where
into the plant from the soil
plants need magnesium to make what
chlorophyll from the leaves
the concentration of ions in the soil is lower than the
concentration of ions inside the root hair celll
active transport is used in a root hair cell to move the ions into where
the cell
the ions active transported to the root hair cell are then transported to where
the xylem vessel and moved to the leaf
root hair cells have got a lot of mitochondria, for what
to provide the energy needed for active transport
the concentration of sugars in the lumen, are lower than the what
the concentration of sugars inside the cell meaning diffusion cant take place
as the concentration of sugars in the lumen are lower than the concentration of sugars inside the cell meaning what has to take place
active transport
