Explanation:
Detailed explanation-1: -So, the correct answer is Lipids.
Detailed explanation-2: -So, the correct answer is Lipids.
Detailed explanation-3: -Carbohydrates are energy-rich. Many, such as glycogen, provide energy-storage functions. Other carbohydrates, such as cellulose-a component of plant cell walls-serve primarily structural roles in a cell. Lipids are the only macromolecules that are not polymers.
Detailed explanation-4: -The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).
