Question

1.What is the importance of pH: (I) In human body? (ii) for aquatic life? (iii) in human digestion?

Answer 1

Answer:

1. Your body's pH balance, also referred to as its acid-base balance, is the level of acids and bases in your blood at which your body functions best. The human body is built to naturally maintain a healthy balance of acidity and alkalinity.
2. If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹².
3. pH plays a crucial role in a normally functioning digestive tract. In the mouth, pharynx and esophagus, pH is typically about 6.8, very weakly acidic. Saliva controls pH in this region of the digestive tract. Salivary amylase is contained in saliva and starts the breakdown of carbohydrates into monosaccharides.
