Step-by-Step Solution:1. Understanding Glycolysis: Glycolysis is a metabolic pathway that breaks down glucose into pyruvate, producing energy in the form of ATP. It occurs in the cytoplasm of cells and does not
10. Transfer of phosphate group: The final step of Glycolysis is the production of another ATP molecule where the phosphate group is transferred from phosphoenolpyruvate to an ADP molecule. The reaction is catalyzed by pyruvate kinase and produces pyruvate. ...

2. Utilizing phosphoglycerate kinase, the 1-3 bisphospho-glycerate is converted into 3-phospho-glycerate. This chemical reaction will move a phosphorous group back onto an ADP molecule, resulting in an ATP molecule being produced. Interesting to note, this step in the reaction process is reversibl...
Step 1. The first step in glycolysis 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. This...
Instead pyruvic acid, which is also the precursor of lactic acid, is converted to ethanol and carbon dioxide by an enzyme-catalyzed two-step process, termed alcoholic fermentation. In the tissues of many organisms, including mammals, glycolysis is a prelude to the complex metabolic machinery that...
The yeast's solution is to divert a portion of dihydroxyacetone-phosphate (DHAP) away from pyruvate formation, where it is reduced to glycerol in a two-step process. The coupled glycerol/pyruvate formation is referred to as glyceropyruvic fermentation. Under anaerobic conditions, certain enzymes ...

The accumulation of intermediates reflects the increased lactate-to-pyruvate ratio; this leads to a secondary imbalance of the nicotinamide adenine dinucleotide-to-reduced nicotinamide adenine dinucleotide (NAD-to-NADH) ratio, which in turn slows down glycolysis at the 3-PGAD step, whose upstream ...
Thus, fatty acid transport can be influenced significantly by intracellular fatty acid metabolism. One critical step in this process is the conversion of fatty acids into fatty acyl-CoA esters, which effectively ‘traps’ the fatty acid within the cell. This process is controlled by acyl-CoA ...
