Question

Describe 3 types of outcomes that might occur as the result of a signaling cascade.

Answer 1

Cell signaling pathway typically triggers a molecular event in order to produce some - large outcome. 1. For instance, growth factor signaling causes a vanety of molemlar changes, including activation of the c-myc transcriphon factor & MNK I translation regulator, to promote the larger response of cell proliferation . Similarly epinephroine triggers, the activate of glycogen in order to provide a muscle cell with fuel for a rapid response. Some important large scale outcomes of cell signaling include cell migration, changes in cell identity, and induction of

apoplosi's Apeplosis : when a cell is damaged, unneeded or polentially dangerous to an organism, it may undergo programmed cell death or apoptosis Internal signalling can lead to apoptosis, but so can siqnals from outside the cell. Apoptosis is essential for normal embryological development. A cell signallina mechanism triggers apoptosis, which desboys the cells between the developmiq digits . Cell miqranón It is a central process in the development & maintanance of multicellubo organisms .Cells oflen migrate in response

to specific external signals including chemical signals & mechanical signals In adulti cell migration occurs cluiring vital cellular processes such as tissue renewal and repair, where in old or damaged cells are replaced by migration of newly formed cells from the underlying tissue layers.
