1. What is the function of acid in the human stomach?
Answer: The walls of our stomach secrete Hydrochloric Acid that facilitates the process of digestion. The acid secreted by the stomach walls form an acidic medium for the food particles in the stomach and dissolves them. The enzyme pepsinogen that helps in the digestion of protein, gets converted into pepsin in the presence of the Hydrochloric Acid. Also, the acid kills the harmful microorganisms present in the food particles and protects us. The HCL in our stomach has a pH of 1 or 2, the low pH indicates that the acidic medium is potent to destroy the microorganisms.
2. How important is Haemoglobin for our life processes?
Answer: Haemoglobin is an iron-containing protein present in our blood that is essential for transporting oxygen from our lungs to all the other body tissues and cells. This protein is present in the Red Blood Corpuscles of our blood. Also, it helps in carrying carbon dioxide from the body tissues and cells to the lungs.
A low level of Haemoglobin can be identified by weakness and is caused due to vitamin deficiency. This can also lead to anemia if not treated properly. A low level of Haemoglobin will lead to a deficit of oxygen in the body cells.
