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

Verified Answer :

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.
