O inhibits the reaction of L to form M. • Q inhibits the reaction of O to form P. • S inhibits the reaction of O to form R. • Which reaction would prevail if both Q and S were present in the cell in high concentrations? a. L M  b. M O  c. L  N d. O P  e. R  S Answer Refer to Figure 9.1 to answer the following questions. Figure 9.1 illustrates some of the steps (reactions) of glycolysis in their proper sequence. Each step is lettered. Use these letters to answer the questions. Figure 9.1 Which step shows a split of one molecule into two smaller molecules? 229. In which step is an inorganic phosphate added to the reactant? 230. In which reaction does an intermediate pathway become oxidized? 231. Which step involves an endergonic reaction? 232. Which step consists of a phosphorylation reaction in which ATP is the phosphate source? 233. The graph here shows the pH difference across the inner mitochondrial membrane over time in an 234. actively respiring cell. At the time indicated by the vertical arrow, a metabolic poison is added that specifically and completely inhibits all function of mitochondrial ATP synthase. Draw what you would expect to see for the rest of the graphed line.
