Answer:
Cellular respiration
Explanation:
Cellular respiration is the process through which organic compounds are broken down enzymatically to release energy in form of ATP in the cell. Cellular respiration occurs in the mitochondria and cytoplasm.
Mitochondria contain enzymes that catalyze and control reactions of respiration. The inner membrane is folded into cristae to create large surface area for attachment of enzymes. The end products of cellular respiration are carbon dioxide, water and energy.
A single molecule of glucose stores more than 90 times the energy stored by ATP. However, ATP, which transfers energy quickly, is used by the cell as an immediate source of energy
D.
They reproduce in a complicated process.
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.
