Detailed explanation-1: -Lipids are also the building blocks of many hormones and are an important constituent of the plasma membrane. Lipids include fats, oils, waxes, phospholipids, and steroids.
Detailed explanation-2: -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).
Detailed explanation-3: -Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism’s genetic code-the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth.
Detailed explanation-4: -Nucleic acids are considered the most significant contributor to cellular function because they have an important role in many biological processes. Nucleic acids are DNA and RNA that are genetic material in the cells.
Detailed explanation-5: -So, the correct answer is Lipids.
