d) Lipids are hydrophobic organic substances, consisting of an hydrocarbon chain
The functions of lipids are;
Fatty acids is a lipid and a building material for other lipids
Phospholipids are a part of cell membranes
Glycolipids take part in the transduction of signals
2) The molecules primarily responsible for cellular energy are adenosine
5'-phosphate and adenosine tri phosphate ATP, obtained from
carbohydrates such as glucose and lipids such as glycerol is transformed
into an intermediate product of glycolysis, and therefore, becomes
involved in cellular energy, therefore, the correct option is option B)
