Difference between Metabolic Alkalosis and Respiratory Alkalosis | Acid-Base Regulation

The upcoming discussion will update you about the difference between Metabolic Alkalosis and Respiratory Alkalosis. Difference # Metabolic Alkalosis: 1. HCO3- excess. 2. pH increased. 3. Disproportionate increase in [HCO3- ], [H2CO3], PCO2, pH. 4. Depression of respiratory centre and hyperventilation leading to retention of CO2. 5. In renal mechanism, there is increased NH3 formation and H+ - Na+ exchange, [...]

Specific Dynamic Action: Factors and Example | Energy Production

The below mentioned article provides a short note on Specific Dynamic Action (SDA). Definition Specific Dynamic Action (SDA): It is defined as the extra heat production over and above the caloric value of a given amount of food when used by the body. Example: An amount of protein which con­tains 100 kcal (25 gm.) when metabolized in the body, the [...]

Measurement of Energy Value of Foods | Biochemistry

The below mentioned article provides a short note on the Measurement of Energy Value of Foods. The foodstuffs (carbohydrates, fats and proteins) on combustion by oxygen produce heat. This amount of heat can be measured in a bomb calo­rimeter. Carbohydrate and fat are completely oxidized in the body to CO2 and water like that of bomb calorimeter. But proteins are [...]
