Multicellular organisms are organisms that are made up of more than one type of cell and have specialized cells that are grouped together to carry out specialized functions. ... Similar cells are grouped into tissues, groups of tissues make up organs, and organs with a similar function are grouped into an organ system.
Chymotrypsin is permanently inhibited by TPCK. Additionally inhibits certain cysteine proteases, including ficin, papain, caspase, and bromelain. For the chemical labeling of active histidine in enzyme analysis, TPCK is chosen. Because the enzyme has a preference for aromatic amino acid residues at the active site, the phenylalanine moiety is attached to the enzyme (as in chymotrypsin, in which it binds to the Histidine-57 residue in the active site).
[1] Neither zymogens nor trypsin are inhibited by it.
In the crystal structure of the complex solved in 2010, TPCK is seen covalently bonded in the active site of Caspase 3.
[2] With the chlorine removed, the chloromethyl group interacts with the cysteine in the active site to form a covalent connection.

The answer is true.
Transitional epithelium of the urinary bladder (urothelium) is a type of stratified (multilayered) epithelium. Layers of epithelial cells in this tissue can contract and expand in order to adapt to the degree of distension needed.
Layer of basal cells (basal layer) consists of cuboidal or columnar cells. Superficial layer, on the other hand, can vary depending on the degree of distension: so, when the bladder is not stretched, the cells are cuboid, but when the bladder is filled with urine, stretched, the cells are squamous.
