What is the link between a first messenger and a second messenger in a cell that responds to peptide hormones?
g protein
What process would you expect the colloid to exit the thyroid cell?
Though a second messenger or receptor and then a g-protein casing signal transduction
Do epinephrine use g-protein linked receptors?
Epinephrine or more commonly known as adrenaline bind to adrenergic receptors. These adrenergic receptors are a type of G-protein coupled receptors
Is protein in sweetcorn?
3.2 g of protein in 100 g of sweetcorn.
What activates a G protein?
GTP activates a G-protein when it displaces the GDP.
Why are G-protein-gated ion channels called the shortcut pathway?
All action of neurotransmitter is eventually (mostly) manifest in the regulation of ion in nerve cell, to decide when to fire or not an action potential. Regulation of ion utilize the ion channel, and there are three (known) mechanism which affect the opening and closing of an ion channel : 1) direct influence - ion channel which is directly activated by neurotransmitter attached to them, this one is called ¨Transmitter Gated Channel¨ 2) shortcut pathways - ion channel which is activated by G-protein, this is called the ¨G-protein-gated ion channels¨ 3) second messenger cascades - G-protein trigger a chain reaction of chemical through enzyme or other class of protein and finally affect the opening and closing of ion channels
Why G protein linked receptor is called as G protein linked receptor?
sciece
What is Transducin?
A G protein
When was G protein-coupled receptors database created?
G protein-coupled receptors database was created in 1998.
The formula Lean Bodyweight in lb x Need Factor equals Minimum Daily Protein Requirement in g is known as the?
Hatfield procedure
What is bound to the G protein in the inactive state?
GDP. Guanine diphosphate. Then the protein is phosphorylated and undergoes a conformational change in concert with its docking with the G protein linked receptor.
Who got noble prize for discovering G protein?
G proteins were discovered when Alfred G. Gilman and Martin Rodbell investigated stimulation of cells by adrenaline. They found that, when adrenaline binds to a receptor, the receptor does not stimulate enzymes directly. Instead, the receptor stimulates a G protein, which stimulates an enzyme. An example is adenylate cyclase, which produces the second messenger cyclic AMP. For this discovery, they won the 1994 Nobel Prize in Physiology or Medicine.
