Nutritional chemists have found that burning 1 gram of fat releases twice the amount of heat energy as burning 1 gram of starch. Based on this information, which type of biomolecule would cause a person to gain more weight?

Question

*
1 point
a. carbohydrate
b. fat
c. proteins
d. nucleic acid

Answer 1

b. fat

Since burning 1 gram of fat releases twice the amount of heat energy as burning 1 gram of starch, it can be inferred that fat contains more energy and therefore has a higher caloric density. This means that consuming more fat would lead to more weight gain compared to consuming the same amount of starch.
