Bch 3025 Exam 3 Questions With Correct Answers If the G'° of the reaction A -> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from left to right. - answerE) will proceed spontaneously from left to right. For the reaction A - B,G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 2...

Step 6 of Glycolysis - Answer-- glyceraldehyde-3-phosphate dehydrogenase uses NAD+ and Pi to oxidize and phosphorylate C1 of glyceraldhyde-3-phosphate to 1,3-bisphosphoglycerate - ATP is not used - NAD+ is reduced to NADH - positive deltaG - active site Cys residue is required Step 7 of Glycolysis - Answer-- phosphoglycerate kinase removes a phosphate group from C1 of 1,3-bisphosphoglycerate and adds it to ADP to make 3-phosphoglycerate and ATP - negative deltaG - helps pull step 6 forw...

CBSE Biochem Lesch-Nyhan Syndrome: what causes it and what are manifestations? - correct answersHGPRT deficiency in purine salvage pathway (this enzyme normally converts hypoxanthine to IMP and guanine to GMP). This deficiency leads to excessive Uric acid production and de novo purine synthesis. It is X linked recessive. Symptoms: hyperuricemia, gout, aggression / self mutilation, mental retardation, dystonia. Treatment for Lesch-Nyhan? - correct answersAllopurinol / febuxostat second ...

Hexokinase - Answer-converts glucose to glucose 6-phosphate in peripheral tissues Glucokinase - Answer-converts glucose to glucose 6-phosphate. present in the pancreatic beta islet cells as part of the glucose sensor and is responsive to insulin in the liver Phosphofructokinase-1 (PFK-1) - Answer-Phosphorylates fructose 6-phosphate to fructose 1,6-biphosphate in the rate limiting step of glycolysis Phosphofructokinase-2 (PFK- 2) - Answer-produces F2,6-BP that activates PFK-1. Activa...

MWU Biochemistry Exam 2 D) In gel filtration, large proteins move most rapidly, but in PAGE, small proteins move most rapidly. - correct answer Which of the following is true regarding gel filtration chromatography and PAGE? A) In both, small proteins move most rapidly. B) In both, large proteins move most rapidly. C) In PAGE, large proteins move most rapidly but in gel filtration, small proteins move most rapidly. D) In gel filtration, large proteins move most rapidly, b...

ACS BIOCHEMISTRY EXAM Q&A With complete solution Henderson-Hasselbach Equation - ANSWER pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - ANSWER Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - ANSWER Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - ANSWER Separates sa...
