Explanation: Answer link WebIn steps [1] & [3] of glycolysis, a/an [kinase] phosphorylates glucose or fructose. These are [irreversible] reactions because they are energetically [favorable] and both steps use up [2 ATP]. Step [2] and [5] are very similar because a type of enzyme called [mutase] moves around the bonds within a molecule, causing a slight change in the ...

WebAug 15, 2024 · This step is also irreversible and is the rate-limiting step. In the following step, fructose 1,6-bisphosphate undergoes lysis into two molecules, which are substrates for fructose-bisphosphate aldolase to … WebStep 1. The first step in glycolysis (Figure 9.1.1) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. …
WebNotice that seven of the ten steps of glycolysis are simply reversed in gluconeogenesis. Reversing the process means that seven steps employ the same enzymes in both pathways. However, there are three steps in glycolysis that are irreversible because they are exergonic processes and cannot be reversed using the same enzymes. Those three …
