1J. Please help me in detail. for molecular Mechanism of ATP versus GTP selectivity of adenylate kinase
The phosphorylation and dephosphorylation of proteins is a vital means of regulation. Protein kinases attach phosphoryl groups, whereas only a phosphatase will remove the phosphoryl group from the target protein. What is the energy cost of this means of covalent regulation?
I don't understand, can I get help? I have attached a picture of everything that will be needed to be annotated. Numerous signaling molecules work together in order for glucagon to induce the regulated release of glucose into the bloodstream. Construct an annotated list of each of these signaling molecules (as learned in the lecture video). For your annotated list, please use the format below. You will need to use this format for each molecule in the pathway that we learned. Name of Molecule:Type of Molecule:Is activated (or inhibited) by:Activates (or inhibits):
Protein phosphorylation and dephosphorylation are important regulatory mechanisms. Protein kinases attach phosphoryl groups to target proteins, while only a phosphatase removes the phosphoryl group. What does this method of covalent control cost in terms of energy?
Which of the following statements is/are correct?a) Enzyme quantities depend on the rate of their synthesis and degradationb) Enzyme quantity is decreased if an amino-acid involved in the catalytic activity is modifiedc) Protein kinase A activity is regulated through protein interaction.d) Kinases control the activity of other enzymes by covalent modification; irreversiblephosphorylation explain each of the following option
Regarding the sodium potassium pump, I am confused which enzymes are involved in the addition of the phosphate group onto the protein to change the conformation. Is it only kinases or kinases AND ATPases? I was under the impression that kinases add organic phosphates onto molecules, while ATPases cleave ATP into ADP and a phosphate group. Would ATPase need to split the ATP molecule before the kinase can transfer the phosphate group onto the sodium potassium pump?
Cite a metabolic pathway where active protein kinase is needed and explain its mechanism of action. Note: Explain it conscisely and precisely
Identify the type of regulation of enzyme activity seen in the following situations - for example, competitive inhibition, allosterism, phosphorylation, zymogen conversion, association-dissociation, feedback inhibition, etc. a. Trypinsogen, which is not catalytically active, is converted to the active enzyme trypsin by removal of a hexapeptide from the N-terminal end. b. The dimer protein kinases is catalytically inactive. Binding of cAMP causes protein kinase dimer to split into its monomer which are active catalysts.
In muscle cells, when adrenaline binds to beta-adrenergic receptor, it trigger signaling cascade leading to active glycogen phosphorylate breaks up glycogen into glucose subunits (Glycogen -> G1P). Base on following figure, describe this signaling cascade:
All the Bold answers are wrong please explain why it is wrong and give me the correct answer. Thanks, in advanced Which of the following is true about enzymes? Enzymes are equally effective across broad ranges of temperature and Ph. Enzymes lower the overall free energy of a reaction to make it spontaneous. Enzyme activity is generally unregulated. Enzymes recognize many substrates with equal specificity. The insulin receptor catalyzes the phosphorylation of several substrates and is therefore classified as a Transferase Phosphate Kinase Lyase Oxidoreductase 3)Which of the following reaction parameters can enzymes optimize to increase reaction rate? The proximity(=closeness) of the reacting groups. The rotational motions of the substrates and catalytic groups. The orientations of the substrates and catalytic groups. The achieve energy needed to achieve the transition state. The catalytic mechanism of RNA relies upon general acid-base catalysis involving the amino acid…
Kinases catalyze the transfer of a phosphate group from a phosphate donor such as adenosine triphosphate (ATP) to a substrate. A well‑known kinase is hexokinase. Hexokinase catalyzes the first step of the glycolysis cycle, and converts glucose to glucose‑6‑phosphate. The reaction of glucose with ATP is shown. The enzyme‑bound base is abbreviated as :B−, and ATP is abbreviated as a diphosphate bonded to adenosine monophosphate (AMP).
