Plasma membranes are physically assembled in the ___.

This organelle is abundant in certain cell types such as gonads and liver where it is used for steroid hormone and lipoprotein synthesis, as well as for the modification of hydrophobic compounds (e.g., drugs) into watersoluble molecules for export.

Uptake of fluids or macromolecules by the cell.

Plays a role in the retrograde movement of microtubules.

Plays a role in the adhesion of epithelial cells to the extracellular matrix.

In belt desmosomes, the transmembrane adhesion molecules are called ___.

Extracellular cell-cell signaling pathway in which cells in just the<br />immediate vicinity are affected.

Checkpoint that monitors the integrity of DNA before irreversibly<br />committing cellular resources to DNA replication.

If the genetic derangement is too severe to be repaired, the cells will undergo ___.

What cyclin –CDK complex regulates G2-M transition?

The most abundant glycoprotein in basement membrane.

This gives the ability of tissues to recoil and recover their shape after physical deformation is conferred by ___.

Also called adult stem cells; they are in niches, are quiescent until there is a need for expansion and differentiation of the precursor pool.

The sequence of events that results in division is called the cell cycle.

Basement membrane

These are multipotent cells that can differentiate into a variety of stromal<br />cells including chondrocytes (cartilage), osteocytes (bone), adipocytes (fat), and myocytes (muscle).

Consists of long polysaccharides called glycosaminoglycans that form<br />highly hydrated compressible gels that confer resistance to compressive<br />forces; in joint cartilage; provide a layer of lubrication between adjacent boney surfaces.

Most of the ATP that powers cells is made through oxidative<br />phosphorylation in the __.

A fluid-phase process during which the plasma membrane invaginates and is pinched off to form a cytoplasmic vesicle.
