Question

Microfibrils are related to
(a)Cellulose
(b)Chloroplast
(c)SER
(d)Phospholipids

Answer 1

Hint They are a complex carbohydrate consisting of oxygen, carbon, and hydrogen. It is chiral, tasteless, and has no odor. They’re used mainly in paperboard and paper production.

Complete answer:
A microfibril is a very fine fibril, or fiber-like strand, composed of glycoproteins and cellulose. It’s basically used as a general term in narrating the structure of protein fiber such as hair and sperm tail. Cellulose microfibrils are laid down within the inner surface of the first cell wall. Because the cell sock up water, its volume increases, and therefore the existing microfibrils divide and new ones are made to assist in increasing cell strength. Microfibrils are elastic and oxytalan fibers that donate mechanical stability and limited elasticity to tissues, give to growth factor regulation, and possess a task in tissue development and homeostasis.

Additional information:
Cellulose is synthesized through cellulose synthase which lives in a cell membrane. Since cellulose fibrils are synthesized and develop extracellularly they move upward against neighboring cells. As the neighboring cell can't move, the Rosette complex is rather propelled round the cell by the fluid phospholipid membrane. Eventually, this leads to the cell becoming wrapped during a microfibril layer. This layer becomes the cell wall. The organization of microfibrils forming the primary cell wall is quite disorganized. However, another mechanism is employed in secondary cell walls resulting in its organization. Basically, lanes on the secondary cell wall are made with microtubules. These lanes force microfibrils to stay during a certain area while they wrap. During this procedure, microtubules can impulsively depolymerize and re-polymerize during various orientations. This results in a special direction during which the cell continues getting wrapped.

So, the correct answer is ‘Cellulose’.

Note: In Marfan syndrome, there's a defect in fibrillin, the glycoprotein component of microfibrils. Cellulose is a long chain of sugar molecules linked together which provides wood its remarkable strength. It's the key component of cell walls for plants, and therefore the essential building block for several textiles and papers. Smaller amounts are converted into a good sort of derivative, like cellophane and rayon. The conversion of cellulose from energy crops into biofuels like cellulosic ethanol as a renewable fuel source is in progress.
