Answer:</h2>
<h3>In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.</h3>
Proteins contain Nitrogen aswell as carbon, hydrogen, oxygen and sometimes sulphur
Answer:
A negative feedback response is generated to lower down the blood sugar level.
Explanation:
When a person consumes a huge amount of sugar, the blood sugar levels are increased beyond the normal range. This deviation from the homeostasis is counteracted by the body. There is an increased secretion of insulin hormone from the pancreas. Insulin triggers the body cells to take up the extra sugar present in the blood to restore its normal range. Since the body generates a response to oppose the increased blood sugar level, it is an example of negative feedback.

<h2><u>Explanation</u> : </h2>
Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulphur.
