What macromolecules are used for energy?

Answer 1

The human body has three macromolecule energy sources: carbohydrates, lipids, and proteins. Carbohydrates are made up of many individual sugar units which are linked together in long chains. The chains can be straight, or they can be branched. Carbohydrates have the molecular formula C6nH(10n+2)O(5n+1) so they only contain carbon, oxygen, and hydrogen. Sugars are used for short to intermediate term storage of energy. That's why drinking a sugary drink can give you energy (a sugar rush) for a short time but then it wears off. The amount of energy in sugar is 4 kcal/g.Proteins are usually made of straight chains of linked peptide units. They provide long term energy storage. Proteins contain carbon, oxygen, hydrogen, and nitrogen with small amounts of sulfur with varying molecular formulas. That is why eating a steak will make you feel full for many hours. Proteins are also used to build up many of the structures in the human body so they are necessary to repair damaged tissue. The amount of energy in protein is 4 kcal/g, just like sugar.Fats are made of up clusters of fatty acids, long chains of repeating CH2 units so they are mostly made of just carbon and hydrogen. Fats are used for long term energy storage. Excess sugar and protein that is consumed by most animals are converted to fats to save the energy for later. The amount of energy in fat is very high, 9kcal/g.

Answer 2

Carbohydrates, fats, and proteins are macromolecules commonly used for energy in the body. Carbohydrates are the body's preferred source of energy, while fats are stored energy reserves. Proteins can also be used for energy when carbohydrates and fats are not available.

Answer 3

Carbohyadrates, but most energy rich are fats.

Answer 4

That is the glucose. It is a monosaccharide

Answer 5

Yes macromolecule such as glycogen and fats are used to store energy for longer period. During fasting, they breaks to form energy. They are regulated by insulin and glucagon hormones.

Answer 6

Glucose is the primary fuel. They are type of monosaccharide

Answer 7

Glycogen, mainly a carbohyadrate.

Answer 8

The main one is glucose.
