Question

What substances form cell membrane and cell wall?

Answer 1

Cell Wall - Cellulose
Cell Membrane - Protein and Lipid

Answer 2

Phospholipids, amphipathic molecules made up of two hydrophobic fatty acid chains linked to a hydrophilic head group containing phosphate, are the basic constituents of all cell membranes. The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides.

Cell membrane:

• The majority of the lipids and proteins that make up cell membranes are based on fatty acids.
• Phospholipids and sterols are the two main forms of membrane lipids (generally cholesterol).
• It is a bilayer of lipids.
• and includes carbs and lipoproteins.
• Phospholipids naturally form stable bilayers with their hydrophobic tails buried inside the membrane and their polar head groups exposed to water.

Cell wall:

• The primary reinforcement for the cell wall is cellulose.
• The cell wall's cellulose is arranged into sturdy beams known as microfibrils.
• The cellulose microfibrils serve as the cell wall's structural foundation.
• A distinctive feature of fungus, the cell wall is mostly made of glucans, chitin, and glycoproteins.
• The majority of the cell wall is made up of peptidoglycan (PG), a network of polysaccharide strands that are cross-linked by short peptide bridges coupled to the MurNAc residues and have a poly-[N-acetylglucosamine (GlcNAc)-N-acetylmuramic acid (MurNAc)] backbone.
