Basidiomycetes are the only fungal group capable of synthesizing lignin peroxidase. What advantage does this group of fungi have
Ber [7]

Answer:

Bascidomycytes are one of the two large divisions within the fungi kingdom.

Explanation:

Bascidomycetes:- Bascidomycytes are one of the two large divisions within the fungi kingdom. they include certain groups such as mushrooms, puffballs, bracket fungi, jelly fungi etc.they are named so becuase these class fungi produce their basidia and basidiospores on or in a basidiocarp. The general life cycle of bascidomycetes is represented with the help of mushroom life cycle because they have close resemblances.

Advantages of Bascidomycetes

  1. Producing multiple spores externally considered to be the distinct feature of this class of fungi
  2. They posses two different extracellular enzyme responsible for the following:-  polysaccharide degradation, consisting mainly of xylanases and cellulases, degradation of  lignin and opens phenyl rings, consisting of laccases, ligninases, and peroxidases.
  3. The ability of this class of fungi to dergade lignocellulose makes it  a useful and potential component for ethanol production
  4. ligninolytic system in bascidomycetes helps in  degrading a wide range of xenobiotic compounds.

Define the 3 signals for activation and the 3 outcomes of the complement system.\
sp2606 [1]
* More than 40 proteins and glycoproteins involved in the complement system are synthesized by the liver, macrophages, epithelial cells, they are present in the blood in plasmatic form, membrane, some have an enzymatic activity, regulator or membrane receptorThese are elements of the humoral innate immune response, they fight infections, purify immune complexes and apoptotic bodies.
<span>There are indeed three ways to activate the complement:</span>
Classical pathway: Activated by Immunoglobulins in immune complexes, aggregated Immunoglobulins, DNA, CRP, apoptotic bodies .......it involves nine fractions, starting with C1, then C4, C2, C3, to form a classical C5 convertase, then, activation of C5, C6, C7, C8, C9.

Alternative pathway: activated by polysaccharides (bacterial endotoxin), vascular wall poor in sialic acid, aggregated IgE ...C3b like is the first component in the alternate channel cascade, it will create an amplification loop, and form an alternative C5 convertase.

Lecithin pathway: Activated by mannose, fucose (carbohydrate of microorganisms)The first component is the complex MBL / MASP1 / MASP2: "mannose-binding protein": works according to the same principle as the complex C1 of the classical way (MASP2 cleaves the C4 and the rest of the cascade is equivalent to that of the classical way).

the three ways have the same outcome: A C5 convertase (formed by one of the pathways) cleaves C5 into C5a and C5b: C5b is deposited far from other fractions on the antigenic surface. The fixation of C5b in the cell is followed by that of C6, C7, C8, and C9 (9 molecules of C9): formation of the membrane attack complex (MAC) ==> Death of the cell by osmotic shock
