Question

Carbohydrates and fats both

1.can be used as an energy source by organisms

2.can be bonded together to construct DNA molecules

3.are made up of the glucose monomer

4.are monomers that can be made into large polymer chains

Answer 1

1.can be used as an energy source by organisms. both carbs and fats feed us. carbs turn to sugar rapidly in the blood - and fats are turned to sugars by the liver.

Answer 2

And to round out the wrong answers, and why they are wrong:

2) DNA is made of bases and sugars, no fats.

3) Only carbohydrates are made from glucose monomers. Fats are made of fatty acids and glycerol.

4) Carbohydrate is already a polymer. Fats are oligimers, but they can't be built up into larger units (polymers).
