D Tonofibrils are made up of keratinous intermediate filaments called tonofilaments. These are components of cytoskeleton of cell. Desmosomes fibrils made up of keratin intermediate filaments and other protein. Desmosomes in the plasma membrane and help in cell adhesion. They are found in the cells of most invertebrates and vertebrates.

Which is correct for the structure of cell wall of bacteria and fungi?
1 Both are made up of cellulose
2 Both have mucopeptide
3 Both are made up of \(\mathrm{N}\)-acetylglucosamine
4 None of these
Explanation:
C The cell wall of fungus is made up of fungal cellulose of chitin and cell wall of bacteria is made up of peptidoglycans. Fungal celluloses or chitin microfibrils are made up of bundles of unbranched chains of \(\beta-14\) acetyl glucosamine residues. Peptidoglycans are the structural elements of almost all the bacterial cell walls peptidoglycans are made up of a polysaccharide backbone consisting of alternation muramic acid acetylated glucosamine residues in equal amount.

The desmosomes are concerned with :
1 cytolysis
2 cellular excretion
3 cell division
4 cell adherence
Explanation:
D A desmosome is a cell structure specialized for cell to cell adhesion, also referred to as a macula adherens. They are localized spot-like adhesions randomly clustered on the lateral sides of plasma membrane a form of junctional complex Desmosomes are one of junctional complex or one of the stronger forms of cell to cell adhesion. These found in tissues, such as cardiac muscle tissue, bladder tissue gastrointestinal mucosa and epithelia.

Catabolism of long chain fatty acids occur in
1 Glyoxysomes
2 Peroxysomes
3 Carboxysomes
4 Ribosomes
Explanation:
B The catabolism of long-chain fatty acids occurs in peroxysomes. These organelles contain enzymes involved in fatty acid oxidation, which breaks down long chain fatty acids to generate energy.
