Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are the functions of a carbohydrate and a lipid similar?
A
Both are a source of energy.
B
Both are replicated during meiosis.
C
Both lower the activation energy of reactions.
D
Both dissolve nutrients in the digestive system.
Explanation: 

Detailed explanation-1: -Carbohydrates and lipids are two of the four important biomolecules. They both are energy sources. However, carbohydrates are available as immediate energy sources while lipids store energy for later use and they release energy at a lower rate. Therefore, this is the key difference between carbohydrates and lipids.

Detailed explanation-2: -Because one triglyceride molecule yields three fatty acid molecules with as much as 16 or more carbons in each one, fat molecules yield more energy than carbohydrates and are an important source of energy for the human body.

Detailed explanation-3: -Carbohydrates have four calories per gram same as proteins, but lipids have nine. Carbohydrates provide more energy than lipids or proteins because they contain more than twice as many calories per gram. The three macronutrients differ in their chemical properties as well.
