Can someone please show your work for tracking the radiolabel: draw structures indicating position of the radiolabeled carbon, giving names (not abbreviations) of metabolites and enzymes, The cell needs ribose 5-phosphate and NADPH. Note the structure, shown above – this is used as a starting point for the formation of ribose 5-phosphate while also generating NADPH. The red asterisk (*) denotes a radiolabeled carbon - where would the radiolabel end up? List all the names’ enzymes and intermediates involved in this conversion. Show all structures.

Complete the description of the pentose phosphate pathway by filling the correct term to each blank.

Cyclic AMP (CAMP) is an important signaling molecule in cells. The synthesis and degradation of CAMP is diagrammed in the following figure: ATP ©2017 Pearson Education, Inc. 12pt Adenylyl cyclase Edit View Insert Format Tools Table Paragraph Pyrophosphate 3'c- P-P₁ 5'C BI Both caffeine (coffee, cola) and theophylline inhibit the enzyme phosphodiesterase that converts CAMP to AMP, allowing cAMP levels to temporarily remain high. Briefly discuss the possible effect of these drugs on the second messenger action of CAMP. What might the effect of caffeine of theophylline be on a signaling pathway?

One of the steps in psilocybin biosynthesis is the phosphorylation of 4-hydroxytryptamine By the enzyme Psik as shown below, that involves the hydrolysis of ATP. NH₂ OH HO Psik HO of A& ADP 4-hydroxytryptamine ATP norbaeocystin The standard free energy changes for each reaction is shown in the Table below. J reaction 4-hydroxytryptamine + P₁ → norbaeocystin ATP → ADP+ Pi (b) What is the equilibrium constant at 37 °C? AG 27.7 kJ/mol -32.2 kJ/mol (a) Write the net reaction. What is the standard free energy change for the net reaction? (c) In the cell, the concentration of ATP is 3.1 mM, the concentration of P; Is 5.90 mM, and the Concentration of ADP is 220 μM. What will AG Be if the concentration of norbaeocystin Is always kept at 1/100 of the concentration of 4-hydroxytryptamine?

Please answer questions 10 and 11 using the first picture for reference.

Intermediates of a pathway are shown in the following scheme. Using curved arrows, show the mechanism of each step labeled with a blue letter. Draw out abbreviated structures of the coenzymes, so that you can effectively show all arrow pushing. You may abbreviate the coenzymes by putting R groups on the molecule, but do draw out the parts of the structure that are involved in the arrow pushing. Some of the transformations will require you to show multiple structures to show all of the arrow pushing (particularly some of the coenzyme-mediated steps). You do not need to show specific amino acid residues that perform the catalysis. You can abbreviate acidic amino acid residues “Enz–B–H” and basic residues “B­–Enz”.
