For each of the following statements, indicate if it is true of the rough ER only, of the smooth ER only, of both rough and smooth ER, or of neither. Sort each statement into the appropriate bin. ResetHelp Is involved in the breakdown of glycogenIs the site for biosynthesis of secretory proteins. Contains less cholesterol than does the plasma membrane. Has ribosomes attached to its outer (cytosolic) surface. Usually consists of flattened sacs. Tends to form tubular structures. Is involved in the detoxification of drugs. Is the site for the folding of membrane-bound proteins. Visible only by electron microscopy.

Explanation:

Rough ER:

Its membranes form flattened piled sacs and elongated tubules, with many ribosomes attached. The main function of the RER is to synthesize proteins that are destined to different target places in the cell. It is also in charge of the proteins folding and maturation.

Smooth ER:

Membrane interconnected tubules that continue with the RER. This reticulum does not have ribosomes attached to its membrane, and this is why it is named smooth. Most of its proteins are synthesized in the RER. SER is abundant in those cells involved in fat metabolism, detoxification, and calcium storage. One of its functions is to produce membrane lipids, including glycerophospholipids and cholesterol. It is also responsible for the elimination of toxic products from the metabolism.SER is also involved in the dephosphorylation of glucose-6 phosphate, allowing glucose to be transported to the exterior of the cell.

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.
