Receptors

Receptors, adrenergic

cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of g-proteins with which they bind; this scheme does not respect the alpha-beta distinction.

How do cockroaches and mosquitoes know the difference betwee

... for both perception of forms and intensity of ligth (and thus perception of a light or dark environment) but invertebrates can also have specific receptors for the intensity of light. From this post http://www.macrostylis.com/en/articles/item/82-polychaetes-and-their-photoreceptors.html it seems ...

My “Eureka” moment. A cure for cancer.

... or "growth factor receptor inhibitors" and possibly other names as well. Those drugs are designed to target cell growth factor receptors and interfere with growth factors activating growth factor receptors to prompt growth in cells. A traditional approach in oncology is to attempt ...

Gender divison in two opposites is greatest mistake of manki

I feel some justification of misogyny at work here. There are some "extra" genes at work, but they are mostly receptors that alter development in a fetus and control reproduction. The "quantity" is true, but fairly pointless.

Re: About how many megapixels would human eye hold?

"The average human retina has five million cone receptors on it. Since the cones are responsible for color vision, you might suppose that this equates to a five megapixel equivalent for the human eye. But there are also a hundred million rods ...
