One function of the carbohydrate macromolecule is to store energy. Which other macromolecule also functions in storing energy?
A
RNA
B
Lipid
C
DNA
D
Protein
Explanation: 

Detailed explanation-1: -The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses. Glucose energy is stored as glycogen, with the majority of it in the muscle and liver.

Detailed explanation-2: -So, the correct answer is Lipids.

Detailed explanation-3: -Answer and Explanation: Carbohydrates and lipids are able to store energy in their bonds. This energy can be accessed by cells by breaking these bonds and using the electrons in these bonds to generate a proton gradient in the mitochondria which will be used to generate ATP molecules by oxidative phosphorylation.

Detailed explanation-4: -The main biological functions of lipids include storing energy, as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes, and form various messengers and signaling molecules within the body.

Detailed explanation-5: -The term macromolecule refers to a polymer of small organic molecules that are useful to accelerate biochemical reactions and created by polymerization. Lipids: The various functions of lipids are cholesterol formation, chemical messengers, and temperature maintenance.
