2-phosphoglycerate(2pg) is converted to phosphoenolpyruvate (pep) by the enzyme enolase. the standard free energy change(deltago’) for this reaction is +1.7 kj/mol. if the cellular concentrations are 2pg = 0.5 mm and pep = 0.1 mm, what is the free energy change at 37 oc for the reaction 2pg ↔ pep? (a) 5.8 kj/mol(b) -5.8 kj/mol(c) +2.4 kj/mol(d) -2.4 kj/mol(e) -4146.4 kj/mol(f) +4146.4 kj/mol

Why is permeable soil best for plants that need a lot of drainage?

From the choices provided below, list the reagent(s) in order that will react with cyclopentanone to form the compound shown below.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
