WebStep 1. The first step in glycolysis ( Figure 7.6) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose. WebOct 15, 2003 · An early divergence in evolution has resulted in two prokaryotic domains, the Bacteria and the Archaea. Whereas the central metabolic routes of bacteria and eukaryotes are generally well-conserved, variant pathways have developed in Archaea involving several novel enzymes with a distinct control. ...

The unique features of glycolytic pathways in Archaea
WebProkaryotes may perform aerobic (oxygen-requiring) or anaerobic (non-oxygen-based) metabolism, and some can switch between these modes. Some prokaryotes have … WebYou may be familiar with this process from products like sauerkraut and yogurt. The chemical reaction of lactic acid fermentation is the following: Pyruvate + NADH ↔ lactic acid + NAD+. Figure 1. Lactic acid fermentation converts pyruvate (a slightly oxidized carbon compound) to lactic acid. In the process, NADH is oxidized to form NAD+. WebA cell might perform anaerobic respiration for which of the following reasons? It lacks glucose for degradation. It lacks the transition reaction to convert pyruvate to acetyl-CoA. It lacks Krebs cycle enzymes for processing acetyl-CoA to CO 2. It lacks a cytochrome oxidase for passing electrons to oxygen. green poncho cape
