Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which biomolecule is the main source of short term energy?
A
carbohydrate
B
lipid
C
nucleic acid
D
protein
Explanation: 

Detailed explanation-1: -Glucose, a 6-carbon sugar, is a simple carbohydrate or “mono-saccharide.” Sugar is a source of quick energy for the body because it is easily metabolized (broken down).

Detailed explanation-2: -The body breaks down most carbohydrates from the foods we eat and converts them to a type of sugar called glucose. Glucose is the main source of fuel for our cells.

Detailed explanation-3: -Animals tend to use carbohydrates primarily for short-term energy storage, while lipids are used more for long-term energy storage. Carbohydrates are stored as glycogen in animals while lipids are stored as fats (in plants carbohydrates are stored as cellulose and lipids as oils)

Detailed explanation-4: -Carbohydrates are involved in the short-term storage of energy in the form of glycogen. The reason it is not as well suited to long term storage is that carbs are polar, hydrophilic molecules, containing several hydroxyl groups.
