Exempel på hur du använder GLYCOLYSIS i en mening

• The wide occurrence of glycolysis in other species indicates that it is an ancient metabolic pathway.
• This pathway is so pervasive because it releases more energy than alternative fermentation processes such as anaerobic glycolysis.
• Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or converted to fatty acids through a reaction with acetyl-CoA.
• Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis.
• By 1936 Meyerhof's laboratory had become one of the world's foremost biochemical facilities focused on processes such as glycolysis and fermentation.
• The anaerobic glycolysis (lactic acid) system is dominant from about 10–30 seconds during a maximal effort.
• Examples of catabolic processes include glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.
• Trioses serve as metabolic intermediates in various different metabolic pathways such as glycolysis, gluconeogenesis, and the pentose phosphate pathway.
• PFK-1 catalyzes the important "committed" step of glycolysis, the conversion of fructose 6-phosphate and ATP to fructose 1,6-bisphosphate and ADP.
• Isomerases catalyze reactions across many biological processes, such as in glycolysis and carbohydrate metabolism.
• All of the hexokinases can mediate phosphorylation of glucose to glucose-6-phosphate (G6P), which is the first step of both glycogen synthesis and glycolysis.
• Its phosphorylated form, dihydroxyacetone phosphate (DHAP), takes part in glycolysis, and it is an intermediate product of fructose metabolism.
• Furthermore, athletes must possess anaerobic endurance over the final 150 to 100 metres of the race as, at this point, lactate (the conjugate base of lactic acid) will accumulate in the body from anaerobic glycolysis.
• In non photosynthesizing tissues, NADPH is generated by glycolysis and the pentose phosphate pathway.
• In comparison, glycolysis has a net yield of 2 ATP molecules and 2 NADH molecules per every one glucose molecule metabolized.
• Glyceraldehyde 3-phosphate, a 3-carbon molecule metabolite important in both glycolysis and the Calvin cycle.
• L-lactate dehydrogenases catalyzes the conversion of L-lactate to pyruvate, the last step in anaerobic glycolysis.
• Other metabolic pathways inferred in LUCA are the pentose phosphate pathway, glycolysis, and gluconeogenesis.
• Glucokinase (GK) in liver cells phosphorylates glucose, preparing it for incorporation into glycogen or for glycolysis.
• Additionally, glycolysis produces reducing equivalents in the form of NADH (nicotinamide adenine dinucleotide), which will ultimately be used to donate electrons to the electron transport chain.
