If a cell has a higher concentration inside then outside, how can it bring in a molecule (cant use diffusion as it moves from high - low, not low - high)
By active transport
1 of 6
Active transport moves molecules from a ___ solution, to a more ___ solution, against the conc. gradient)
From diluted. To conontrated
2 of 6
This requires ___ from respiration
Energy
3 of 6
How is active transport different from diffusion?
It moves from low-high conc (against gradient) while diffusion moves high-low (down gradient). It requires energy from respiration while diffusion doesn't
4 of 6
An example of active transport is digested molecules (sugar) transporting from the l____(cavity where food digested - in small intestine), into the cell and then into the b___, to be carried around the body.
From lumen. Into bloodstream
5 of 6
How is energy provided for active transport in this particular example?
Cell contain mitochondria, that is the site of respiration, tat provides the energy needed.
