Most of the metabolic activity of the cells occur in cytoplasm.
The cytoplasm is the fluid present in the empty spaces of the cell. All the organelle are found floating in the cytoplasm. Most of the cellular activity and formation takes place here. The nucleus is mainly responsible for the storage of genetic material and synthesis of mRNA. The cell wall is responsible for transportation. In nucleus as well as cell wall do not have space, where the metabolic reactions takes place. Hence, most of the reaction takes place in cytoplasm.

Answer:
1) The Small Intestine. It absorbs most of the nurtients in our food. The circulatory system passes them on to other parts of the body to store or use. Special cells help absorbed nutrients cross the intestinal lining into the bloodstream.
2) The small instestine; although the small intestine is narrower than the large intestine, it is actually the largest section of the digestive system tube, that is measures about 22 feet (or seven meters) on average, or 3 1The /2 times the length of tthe body.
3) The small intestine, despites its name, is the largest part of the gastrointestinal tract. It works with other organs of the digestive system to further digest food after it leaves the stomach and absorbs nurtients.
