What are the roles of second messengers in signal transduction pathways?
WasanWasafb6132
The term second messenger was given with the discovery of chemicals that work inside the cell. Hormones and other molecules that function outside the cell are called first messengers in the transmission of information.

∙ 12y agoMost subcellular processes are homeostatic, such that different types of cellular processes occur when there are higher and lower cytosolic concentrations of certain molecules. Most textbooks frame the issue in the way that certain types of membrane-bound metabotropic receptors couple with and activate g-proteins. The g-protein then couples with a substrate and either produces or metabolize second messengers like ATP or GTP.

What cascades are included in many of signal transduction pathways?
Probably the most common of the signal transduction pathways is through the use of G proteins. These proteins are found with three subunits. When activated by a GPCR, or a G Protein-Coupled Receptor, they drop off bound GDP and pick up GTP and the subunits separate. G-alpha will help phosphorylate other proteins which end up amplifying the signal. This leads to many signaling pathways.
Cells communicate with one another via?
Cells in the body communicate with one another via signal transduction pathways. A cell needs to communicate with other cells to survive.
What is an arrestin?
An arrestin is any of a group of proteins which regulate signal transduction within cells.
The process of transduction usually begins?
When the signal molecule changes the receptor protein in some way.
What is serpentine receptor?
A serpentine receptor is a receptor in the cell membrane that plays a role in signal transduction.
Why do signal transduction pathways need amplifiers?
provides pathways to immune and intracellular sheilds
What does a protein phosphatase actually do to end a signal transduction?
Protein phosphates turn off signal transduction pathways by removing the phosphate groups from the protein kinase, making them reusable and making the kinase inscribe stopping the signal transduction pathway.

What is the role of motif in signal transduction?
the role of Motif in signal transduction

What are similarities of plant and animal hormones?
Animal and plant hormones play an important role in the growth and development of the species. They work by the existence of specific pathways, and complex signal transduction.
What is a signal transduction?
A signal transduction is a really complicated process when a molecule signals to a receptor which then alters other molecules as a response to this. The signal can produce a wide variety of responses.
