How do substances work by altering the ways cells function?
Like the receptors for other protein hormones, the receptor for insulin is embedded in the plasma membrane. The insulin receptor is composed of two alpha subunits and two beta subunits linked by disulfide bonds. The alpha chains are entirely extracellular and house insulin binding domains, while the linked beta chains penetrate through the plasma membrane. The insulin receptor is a tyrosine kinase. In other words, it functions as an enzyme that transfers phosphate groups from ATP to tyrosine residues on intracellular target proteins. Binding of insulin to the alpha subunits causes the beta subunits to phosphorylate themselves (autophosphorylation), thus activating the catalytic activity of the receptor. The activated receptor then phosphorylates a number of intracellular proteins, which in turn alters their activity, thereby generating a biological response. Several intracellular proteins have been identified as phosphorylation substrates for the insulin receptor, the best-studied of which is insulin receptor substrate 1 or IRS-1. When IRS-1 is activated by phosphorylation, a lot of things happen. Among other things, IRS-1 serves as a type of docking center for recruitment and activation of other enzymes that ultimately mediate insulin's effects. from yo mama
Oxidation is a reaction in which a compound or molecule gains electrons thereby giving it negative character?
this statement is false!! ------------------------------------------------ Platoweb.com :)
What organic molecule is a prion?
A prion is a misfolded protein that fosters misfolding in other normal proteins, thereby resulting in disease.
What new product is formed at the DNA strand?
RNA does, in contrast to DNA, form short double strand structures on itself, thereby forming so called stem and loop structures.
What is a protein molecule that acts as a biological catalyst to speed up chemical reactions by lowering the energy of activation?
The presence of catalysts, usually enzymes.

How do you punctuate using the word thereby?
The word "thereby" is usually set off by commas when it is used in the middle of a sentence. For example, "He studied hard, thereby improving his grades." If "thereby" is used at the beginning of a sentence, it is typically followed by a comma. For example, "Thereby, he improved his grades significantly."

Which process involves antibodies covering surface receptors on a virus or toxin molecule thereby disrupting their activity?
Neutralization
What does thereby mean?
thereby is used to state or introduce the result of a situation mentioned beforehand example- regular workout strengthens the heart, thereby reducing the risk of heart attack
What organic molecule is a prion?
A prion is a misfolded protein that fosters misfolding in other normal proteins, thereby resulting in disease.
Why Fresh frozen plasma is given to patients with dengue instead of platelet?
fresh frozen plasma by Fc receptor blockade will inhibit immune mediated destruction of platelets and thereby increase the platelet count
Does the molecule that functions as a reducing agent in a oxidation-reduction reaction gain or lose electron?
A reducing agent loses electrons and is thereby oxidised.
Why is nitrogen chloride a nonpolar molecule?
Assuming you are referring to nitrogen trichloride, then it IS polar, it is NOT chiral though. NCl3 has C3V symmetry and therefor is polar. The molecule is NOT planer due to the lone pair on Nitrogen so the bond dipoles do NOT cancel thereby making it Polar.
How does heat flow during heat transfer?
Heat flows through a substance when heat is provided to a substance, the molecules that receives it first gets excited and begins to vibrate to and fro thereby hitting another molecule and transferring this vibration to more molecules thereby transferring the heat energy.
Molecules bind to receptor sites and are enclosed in vesicles in the process of?
Endocytosis During endocytosis a small patch of plasma membrane folds in and encloses particles or tiny volumes of fluid at the cell surface.The membrane enclosure then pinches off into the cytoplasm,thereby forming a cytoplasmic vesicle
Where do you find anticodon?
The anti-codon is the molecule of mRNA in the nucleus which copies the codon from DNA in reverse. This process is reversed again when tRNA copies the mRNA in reverse, thereby restoring the original codon sequence.
