The digestion of proteins, take place by enzymes called proteases, which begins in the stomach, where pepsin breaks down some proteins into polypeptides. The end products of protein digestion are amino acids which can be absorbed.

Changes in pH which can accompany metabolic process such as respiration (aerobic glycolysis for example) can alter the conformation of an enzyme and hence enzyme activity. The initial changes are covalent (change in protonation state of the protein) which can lead to an alteration in the delicate balance of forces that affect protein structure

Entomology is the scientific study of insects, a branch of arthropodology, which in turn is a branch of biology. It is derived from the Greek word ‘entomos’ which means “that which is cut in pieces or engraved/ segmented”, hence “insect”.

The normal range of concentration of fasting blood sugar is 80 to 120 mg/ml; in the testing of true blood sugar, the normal range of concentration is 70 to 100 mg/ml. So normal glucose levels fall between 70 and 150 mg. Higher levels may indicate diseases such as diabetes mellitus.
