This reaction may be mediated by pyruvate dehydrogenase kinase (PDK) 4, the major PDK isozyme expressed in erythroblasts undergoing enucleation. Collectively, these results suggest that ATP produced by anaerobic glycolysis is the main source of energy for human erythroblast enucleation in the hypoxic ...
Understand the process of glycolysis and learn the steps involved. Identify the products of glycolysis. Related to this Question How many ATP molecules are produced and consumed by glycolysis? How many ATP molecules (overall) are generated per glucose molecule during glycolysis?
A leading explanation is that glycolysis is more efficient in terms of ATP production per unit mass of protein (that is, faster). Through quantitative flux analysis and proteomics, we find, however, that mitochondrial respiration is actually more proteome efficient than aerobic glycolysis. This is ...
Given that plants produce ATP and NADPH from photophosphorylation, for what purposes do they reduce CO2 to triose phosphate? a. At night, plants need the ATP produced by glycolysis and oxidative phosphorylation in the dark. b. Plants need triose phospha ...
Pyruvate produced by glycolysis enters mitochondria. Pyruvate is completely oxidised to three molecules of CO2 in mitochondria.Pyruvate undergoes oxidative decarboxylation in the mitochondrial matrix by the enzyme pyruvate dehydrogenase complex. NADH is produced in this reaction. The acetyl CoA thus produced...
Tissues derive ATP from two pathways—glycolysis and the tricarboxylic acid (TCA) cycle coupled to the electron transport chain. Most energy in mammals is produced via TCA metabolism1. In tumours, however, the absolute rates of these pathways remain
In certain circumstances there is evidence that ATP produced by glycolysis plays a significant role in the control of potassium channel activity. The concept of subsarcolemmal ATP is another explanation for the activation of the channel at relatively high ATP concentrations. Potassium channel closing ...
During this process, electrons are transferred through a series of protein complexes in the inner mitochondrial membrane, creating a proton gradient that drives the synthesis of ATP by the enzyme ATP synthase. In addition to oxidative phosphorylation, ATP can also be produced through glycolysis, the...
As the intensity of the activity means greater flow rates, the pyruvate and hydrogen ions produced by glycolysis will undergo lactic fermentation, resulting in the production of lactate ions (4). Alactic anaerobic metabolism Finally, during short but very intense exercise (sprinting...
molecule of glucose. It consists of a series of stages, beginning in the cell cytoplasm and moving to the mitochondria, the "power plants" of eukaryotic cells. The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring...
