In the first step of glycolysis, the given two reactions are coupled. reaction 1: glucose + P i ⟶ glucose - 6 - phosphate + H 2
O Δ G = + 13.8 k J / mol reaction 2: ATP + H 2 O ⟶ ADP + P i Δ G = − 30.5 k J / mol Answer the four questions about the first step of glycolysis. Is reaction 2 spontaneous or nonspontaneous? nonspontaneous spontaneous Complete the net chemical equation. ATP + ⟶ + Calculate the overall ΔG for the coupled reaction. Δ G = kJ / mol Is the first step in glycolysis spontaneous (favorable)? no yes
Glycolysis is the process in the field of chemistry in which a specific glucose molecule is broken down to become two or more molecules of pyruvic acid or pyruvate. The process and procedure is a metabolic multi-step pathway that happens in the cytoplasm of plant cells, animal cells, and the cells of various microorganisms.
