Four ECM ubiquitous protein components, each of which comprises multiple, distinct, repeating domains, are found in basal laminae. Given below are a list of some extracellular matrix (ECM) proteins in column A and their characteristics in column B.

Column A	Column B
a. Type IV collagen	i. a large multidomain proteoglycan that binds to and cross-links many ECM components and cell-surface molecules.
b. Laminins	ii. a rodlike molecule that cross-links type IV collagen, perlecan, and laminin, which helps incorporate other components into the ECM and also stabilizes basal laminae.
c. Perlecan	iii. a family of multi-adhesive, cross-shaped proteins that form a fibrous two-dimensional network with type IV collagen and that also bind to integrins and other adhesion receptors.
d. Nidogen	iv. trimeric molecules with both rodlike and globular domains that form a two-dimensional network.

Pyruvate is coverted into the Acetyl-CoA, Acetyl-CoA contain the acetyl group which are comes from the pyruvate and Coenzyme A (CoA) that contain other groups such as;

a) A reactive thiol (—SH) group that is critical to the role of CoA as an acyl carrier in a number of metabolic reactions

b) contain pantothenic acid,  A hydroxyl group of pantothenic acid is joined to a modified ADP moiety by a phosphate ester bond

c) pantothenic acid carboxyl group is attached to β-mercaptoethylamine in amide linkage

d) Hydroxyl group at the 3’ position of the ADP moiety has a phosphoryl group not present in free ADP
