Lipids are organic compounds that contain the same elements as carbohydrates: carbon, hydrogen, and oxygen. However, the hydrogen-to-oxygen ratio is always greater than 2:1. More important for biological systems, the carbon-to-hydrogen bonds are nonpolar covalent, which means that lipids are fat soluble and will not dissolve in water. There are four biologically important lipids:

Answer:
<em>Three important energy carrier molecules in a cell are: ATP (Adenosine triphosphate, NADPH (Nicotinamide Adenosine Dinucleotide Phosphate) and FADH2. </em>
Explanation:
All the three carrier molecules play an important role in cellular respiration and photosynthesis. One NADH molecule is equal to 3 ATP molecule while 1 FADH2 molecule is equal to 2 ATP molecule.
During the active process, ATP is used as a form of energy because ATP dephosphorylates to ADP and Inorganic phosphate, Pi and release energy.

The appendicular skeleton is the skeleton system of vertebrates which includes the bones of upper limbs, lower limbs and the shoulder girdles and pelvic girdles which attaches the upper limb and the lower limb.

Thus, option-A is the correct answer.
