What is the major source of phosphate for most kinases?
The answer is:
the source of phosphate in most kinases is
High energy ATP molecules.
kinase enzyme transfers phosphate group in a process called phosphorylation.
Phosphatases are a family of enzymes that remove phosphate groups from specific proteins; these phosphate groups had been added to the proteins by protein kinases. Vanadate is an inhibitor of phosphatases in eukaryotic cells. What effect would vanadate have on the response of cells to signals received by receptor kinases? A) The signal would still bind the receptor, so there would be no effect. B) The response of the cell would last longer than it normally would. C) The response...
Kinases, which are responsible for the activation of a number of proteins, serve to add phosphate groups onto all below except A) Tyrosine Residues B) Serine Residues C) Theronine residues D) Cysteine Residues
The activity of many enzymes is regulated by reversible covalent modifications. Kinases add a phosphate group from an ATP to a specific hydroxyl group on an amino acid residue within an enzyme. Which of the following amino acids can be phosphorylated by a kinase? (Select all that apply) Cys His Tyr Thr Phe Ser Val
What type of receptor is used by most growth factors (e.e EGF, FGF)? Whereas an RTK will phosphorylate tyrosine residues on proteins, the other major family of protein kinases phosphorylates proteins on Approximately how many protein kinases are encoded in the human genome? residues. or
Which is true of Receptor Tyrosine kinases? Most RTK subunits are single-pass transmembrane proteins. They are seven-pass transmembrane proteins. They are coupled to ion channels in the membrane They contain lots of tyrosine residues in their transmembrane domains
What is the major role of pyridoxal phosphate in metabolism? Name a purine nucleoside. Name a pyrimidine nucleoside What is the difference between a nucleoside and a nucleotide. What two molecules (that contain more than 5 atoms each) are used to donate nitrogen atoms into the urea cycle? What is the role of the amino acid carnitine? What is the major role of the amino acid glutamine in nitrogen metabolism?
What is the most common source of income in most countries?

Question 7 1 pts Phosphorylation of kinases in one location can result in activation, while phosphorylation in another location on the same protein can result in deactivation of the enzyme. True False Question 8 2 pts Dephosphorylation, or removal of a phosphate group, is accomplished with the help of a both kinases and phosphatases neither kinases not phosphatases phosphatase kinase Question 9 1 pts Select all of the following that act as second messengers.
