Detailed explanation-1: -The primary source of energy for animals is carbohydrates, mainly glucose. Glucose is called the body’s fuel. The digestible carbohydrates in an animal’s diet are converted to glucose molecules through a series of catabolic chemical reactions.
Detailed explanation-2: -Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.
Detailed explanation-3: -Carbohydrates are the preferred source of energy. If the diet does not provide adequate carbohydrates the body will draw mainly upon proteins for its energy needs. By eating adequate amounts of carbohydrates, proteins will be spared to be used for growth, development and regulatory functions of the body.
