Lipid molecules can store double amount of energy as compared to same amount of carbohydrate because of high number of__________________?
Correct answer: B. C-H bonds
- A. C-C bonds
- B. C-H bonds
- C. C-N bonds
- D. C-O bonds
Explanation
Lipids contain many reduced C-H bonds, and oxidation of these bonds releases substantial energy; this is why fats yield about twice as much energy per gram as carbohydrates. Students may choose C-C bonds because carbon chains are prominent in lipids, but the greater energy yield mainly reflects the abundance of hydrogen and C-H bonds.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
