The final step in glycolysis catalyzed by pyruvate kinase couples the hydrolysis of phosphoenolpyruvate (pep) to the formation of atp via substrate-level phosphorylation of adp. if the δg°' of atp + h2o → adp + pi + h+ is –30.5 kj/mol and the δg°' of the coupled reaction is –31.4 kj/mol, what is the δg°' of pep + h2o → pyruvate + pi?

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

. ph changes the ability of them he enzyme to dissolve in water.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
