Which of the following is a true statement? a) fats contain half the amount of energy than carbohydrates because they have less bonds. b) carbohydrates contain more energy than lipids because their bonds release more energy when broken. c) lipids contain more energy than carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.

Option C

Explanation:

The energy that is required by the body is primarily stored in the form carbohydrates. The energy from the carbohydrates is easily converted into a usable form which is adenosine triphosphate.

The energy from the carbohydrates can be derived easily but from lipids it is difficult. Lipids contain more energy than carbohydrates because they contain more carbon to hydrogen bonds and when these bonds are broken down they release energy.

This energy is much more than carbohydrates. Hence, the maximum energy in the molecules is in lipids.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
