Question

phospholipids are essential in cells because they: build ribosomes help maintain the cell membranes structure and balance store oxygen molecules convert glucose into atp

Explanation:

Phospholipids form the lipid bilayer of the cell membrane. Their amphipathic nature (hydrophilic head and hydrophobic tail) allows them to self - assemble into a bilayer structure. This bilayer is crucial for maintaining the integrity and selective permeability of the cell membrane. Ribosomes are built from ribosomal RNA and proteins. Oxygen is transported (not stored in a significant way by phospholipids) by molecules like hemoglobin. The conversion of glucose into ATP occurs through cellular respiration processes (glycolysis, Krebs cycle, electron transport chain) involving enzymes and other molecules, not phospholipids.

Answer:

Help maintain the cell membrane's structure and balance
