Color vision is one of the primary senses of human beings that provide the perception of our environment. When light penetrates to the eyes through the pupils, it falls on the retina where photons of the light agitate the rod and cone cells. Rod and cone …
Eyes of animals are very sensitive to light. Light detection by eyes is accomplished by sensory neurons that are specialized to use signal transduction mechanisms similar to those that detect hormones, neurotransmitters and growth hormones. The initial signal is amplified by mechanisms involved in gated ion …
G-Protein Linked Cell Surface Receptors (GPCRs) GPCRs are the membrane proteins that constitute the largest superfamily of the protein. In the human genome, there are more than 800 G-protein linked cell surface receptors that are categorized into four superfamilies; Rhodopsin-like GPCRs, secretin-like/adhesion-like GPCRs, glutamate, and frizzled/Tas2 …
