HUMAN NUTRITION

Detailed explanation-1: -Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.

Detailed explanation-2: -Protein can be metabolized and used as an energy source for the body, but it’s not the “preferred” source of energy. Our bodies are all about efficiency, and carbohydrates are our primary source of food energy because they’re fast-acting and can be easily broken down into usable glucose.

Detailed explanation-3: -Carbohydrates, also known as carbs, are vital at every stage of life. They’re the body’s primary source of energy and the brain’s preferred energy source. Carbs are broken down by the body into glucose – a type of sugar.

Detailed explanation-4: -Humans obtain energy from three classes of fuel molecules: carbohydrates, lipids, and proteins. The potential chemical energy of these molecules is transformed into other forms, such as thermal, kinetic, and other chemical forms.
