What is enzyme and characteristics?
Enzymes are biological catalysts that facilitate chemical reactions in living organisms. They are typically proteins, although some RNA molecules also have catalytic activity. Enzymes are essential for life because they speed up the reactions that are necessary for cells to function properly. Without enzymes, many biochemical reactions in the body would occur too slowly to…
MCQ on Breathing and Exchange of Gases-2
Visiting high mountains may cause altitude sickness in men living in plain areas. Prime cause of this is (a) excess of CO2 in blood (b) decreased efficiency of haemoglobin (c) decreased partial pressure of oxygen (d) decreased proportion of oxygen in air. Increase in body temperature makes oxygen haemoglobin dissociation curve (a) shift to left…
