5 concepts
Termination of the Signal Cascade
Signal cascades convey signals to the cell through the phosphorylation of molecules by kinases.
Cell Signaling and Gene Expression
Gene expression, vital for cells to function properly, is the process of turning on a gene to produce RNA and protein.
Cell Signaling and Cellular Metabolism
The rush of adrenaline that leads to greater glucose availability is an example of an increase in metabolism.
Cell Signaling and Cell Growth
Cell growth is promoted by ligands known as growth factors.
Cell Signaling and Cell Death
When a cell is damaged, unnecessary, or dangerous to an organism, a cell can initiate the mechanism for cell death known as apoptosis.
