Concept Introduction:
Coenzymes are non-protein organic compound that binds with enzymes to catalyze a reaction. Coenzymes are often called as co-factors but it is chemically different. Coenzymes cannot function alone but they can be reused several times when paired with enzymes. Without co-factors or coenzymes, enzymes cannot catalyze the reaction effectively.

- The first step of the metabolic process known as glycolysis is the conversion of glucose to glucose- 6-phosphate. This process has a positive value for rG' Glucose + Pi Glucose-6-phosphate + H2O rG' = +13.8 kJ/mol-rxn This reaction is coupled to the hydrolysis of ATP ATP + H2O ADP + Pi rG' = -30.5 kJ/mol-rxn What is the sum of these two equations and the value of rG' for the coupled reaction? Is the coupled reaction product-favored at equilibrium?arrow_forwardStearic acid is the common name for the C18 straight-chain, saturated fatty acid. Draw the structure of the fatty acyl-CoA that this forms (you don't have to draw out all of the atoms in coenzyme A; you can represent it as S-, and then show all of the reactions). Draw & identify all of the compounds formed when the eighteen carbon fat is converted to two molecules of acetyl-CoA and the fourteen-carbon fat via two turns of the fatty acid spiral. List the enzymes and coenzymes that are part of the pathway.arrow_forwardTPP is a coenzyme for transketolase, the enzyme that catalyzes the conversion of a ketopentose (xylulose5-phosphate) and an aldopentose (ribose-5-phosphate) to an aldotriose (glyceraldehyde-3-phosphate) and a ketoheptose (sedoheptulose-7-phosphate). Notice that the total number of carbons in the reactants and products is the same (5 + 5 = 3 + 7). Propose a mechanism for this reaction.arrow_forward

Glycolysis is a metabolic pathway that converts glucose into pyruvate while synthesizing high-energy molecules. During one step of Glycolysis, glucose-6-phosphate (an aldose) is converted to fructose-6-phosphate (a ketose) via an ene-diol intermediate.
