Draw out the transferase mechanism for first step of glycolysis (Glucose to G6p). Start with deprotonation and include the trigonal bipyramidal intermediate.
2. Synthesis of 1-hexanol. a) Suggest one base that can deprotonate 1-butyne. b) When the deprotonated 1-butyne reacts with epoxyethane, CH3CH2CCCH2CH2O- forms. Draw this step's curly arrow mechanism. c) Suggest an acid that will covert CH3CH2CCCH2CH2O- to CH3CH2CCCH2CH2OH. d) What reagents are needed to convert CH3CH2CCCH2CH2OH to 1-hexanol?
Please help Practice Worksheet 8: Alkyne 3. Alkynes are deprotonated (remove H) by strong base leg.. NaNH then can undergo SN2 substitution with electrophiles such as alky in the missing boxes for each alkylation. The first reaction is shown as move H) by strong base lee Na Hal to give acetylide ions. These ution with electrophiles such as alkyl halides and alkyl sulfonates. Fill en alkylation. The first reaction is shown as an example of an alkylation a. NaNH, NH3...
Draw a simplified, balanced reaction for the glycolysis of glucose (conversion to pyruvate) and another simplified reaction for the glycolysis of any pentose (show initial conversion to glyceraldehyde, leading to pyruvate). Best answer gets a rating! Thanks!
4. (6 points) a. Draw the product(s) of an aldol cleavage carried out on glucose-6-phosphate. (This reaction is not part of glycolysis, but please give the products of what this reaction would be if it took place.) b. Explain why the aldol cleavage in glycolysis takes place on fructose-1,6-bisphophate instead of glucose-6-phosphate.
Hexokinase catalyzes the first step of glycolysis, in which glucose is phosphorylated to form glucose-6-phosphate. Which of these statements are accurate? The conformational shift that occurs when glucose, but nox water, enters the active site prevents water from hydrolyzing ATP Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. Hexokinase consists of two domains, or lobes, that come together when glucose and...
The first reaction in glycolysis is the phosphorylation of glucose:Pi+glucose⟶glucose−6−phosphate+H2OThis is a thermodynamically unfavorable process, with ΔG∘′=+13.8kJ/mol.Part AIn a liver cell at 37 ∘C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each. =>theequilibrium concentration of glucose-6-phosphate = 1.2*10^-7 MPart BThis very low concentration of the desired product would be unfavorable for glycolysis. In fact, the reaction is coupled to ATP hydrolysis to give the overall reactionATP+glucose⟶glucose−6−phosphate+ADP+H+ΔG∘′ for the coupled reaction is -18.4 kJ/mol
Drawing Glycolytic intermediates. Glucose labeled with 14_C at C-1 was incubated with the glycolytic enzymes and necessary cofactors. Draw structures to show the transformation of glucose to two molecules of glyceraldehyde 3-phosphate via the first half of glycolysis, clearly indicating the position of the 14_C label at each step. You do not need to show reaction mechanisms for each reaction.
2. The first step in glycolysis is catalyzed by the enzyme herokinase: glucose + ATP glucose-6-P + ADP This reaction can be thought of as two coupled reactions (P is phosphate): (1) glucose + P + glucose-6-P (2) ATP + ADP + P For the overall reaction, AG" = -16.7 kJ/mol. For the hydrolysis of ATP (equation 2), AG = -310 kJ/mol. All reactions are performed at 37°C. (a) What is AGº for reaction 1? Iglucose - 6-11 if AG...
Glycolysis is the process by which energy is harvested from glucose by living things. Several of the reactions of glycolysis are thermodynamically unfavorable (nonspontaneous), but proceed when they are coupled with other reactions. Which of these reactions is (are) unfavorable? Select all that apply. Which of these reactions can be coupled so that overall reaction is favorable? Select all that apply. What is the net change in free energy if one selection from part (b) is coupled so that the...
