Which type of transport is used to move s molecule from a region of low concentration to a region of high concentration

Facilated diffusion only works from high to low concentration. A transport protein binds to the substance on one side of the cell membrane and then releases it on the other side. ACTIVE TRANSPORT involves the transport of molecules from regions of low concentration to regions of high concentration.

Active transport.

Explanation:

Active transport is the process in which molecules or particle move against the gradient i.e from regions of lower concentration to the regions of higher concentration. In bio process, molecules undergoing active transportation usually move by utilizing the energy produced during respiration. The active transportation usually takes place when some molecules are at high concentration inside the cell but they are required by the organism, then carrier protein moves these specific molecules through the process of active transport.

answer; /// i do believe the correct answer is (

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
