What is the function of proteins and carbohydrates that are embedded in a cell membrane? a. they provide nutrients that the cell needs. b. they control what enters and leaves the cell.

The function of proteins and carbohydrates that are embedded in a cell membrane is:

B. They help control what enters and leaves the cell.

Explanation:

Even though the most common contribution of proteins and carbohydrates is to provide energy to the cell. When they are attached to the membrane they work as catalyst or filter and they decide what type of substances pass through the cell membrane. This happens because their covalent links allow them to balance the membrane and identify the substances required to work properly.

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.

weathering is the answer.
