Question

More energy can be released from a fat molecule

than from a glucose molecule because the fat
molecule contains more
(1) genes (3) chemical bonds
(2) organic compounds (4) mitochondria

Answer 1

The correct answer is 3.

Energy is stored in chemical bonds. So, a molecule with more chemical bonds will have more stored energy, which can then be released. If a fat molecule releases more energy than a glucose molecule, then it must have more chemical bonds.
