What is the extracellular matrix of epithelial cells called? a. Adipose tissue b. Basement membrane c. Cartilage d. Desmosome e. Endothelium Extracellular Matrix: An extracellular matrix is a network of macromolecules like enzymes, col...
In the pollen cell wall an extracellular TG co-localizes with substrates and cross-linked products; it is required for the apical growth of pollen tubes. The pollen TG is also secreted into the extracellular matrix possibly allowing the migration of pollen tubes during fertilisation. Although ...
What is the main component of the cell wall of bacteria? What are cell walls of fungi composed primarily of? Like plants, fungi have what; however, in plants they are composed of what, whereas in fungi, they are composed of: a. cell walls; cellulose; chitin b. cell walls; c...
In particular, the proteins involved in the adhesion of the cell to the extracellular matrix share many functional properties. At the sequence level, however, a surprising lack of homology is found between adhesion-related proteins of plants and animals. Both protein machineries only reveal ...
The hook is a short curved structure that joins filament with the basal body. It produces repulsion like the propeller during the revolving of flagella. The basal body is a set of rings embedded in the cell wall and plasma membrane. It consists of 2 pairs of rings in Gram-Negative bacteria...
Cell Wall in Plant CellsLike plant cells, animal cells have a cell membrane. This is an important barrier that separates the interior parts of the cell from the external environment while also regulating the movement of molecules/substances in and out of the cell....
Blackberry extract is an intelligent active ingredient, stimulating collagen synthesis in the dermis and exerting a positive impact on skin firmness, helping the extracellular matrix to adapt better to changes in volume. Tetrapeptide Tetrapeptide Peptides are substances present in nature and in our bo...
Cell states Epigenetics 1. Introduction Most accept that cellular dedifferentiation is a process by which cells revert from their differentiated state back to a less-differentiated state. Purists argue that, like differentiation, the definition of dedifferentiation requires the recognition of the destination...
What is the process by which particles move from a region of low concentration to a region of high concentration against the concentration gradient called? Solutions that have a higher solute concentration than the inside of a cell are called what?
Common protocol to measure the affect of extracellular signals on protein expression is to transfect a cell line with a plasmid expressing a reporter (such as luciferase) under the control of known transcriptional control elements. However, this assay comes with two main constraints. First, exogenous...
