Metabolic activities in normal cells rely primarily on mitochondrial oxidative phosphorylation (OXPHOS) to generate ATP for energy. Unlike in normal cells, glycolysis is enhanced and OXPHOS capacity is reduced in various cancer cells.

2011年6月1日 · Comparison of glycolysis and oxidative phosphorylation as energy sources for mammalian sperm motility, using the combination of fluorescence imaging, laser tweezers, and real-time automated tracking and trapping

2023年8月8日 · Glycolysis occurs in both aerobic and anaerobic states. In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis.

The general enhancement of the glycolytic machinery in various cancer cell lines is well described and recent analyses give a better view of the changes in mitochondrial oxidative phosphorylation during oncogenesis.

In contrast to normal differentiated cells, which rely primarily on mitochondrial oxidative phosphorylation to generate the energy needed for cellular processes, most cancer cells instead rely on aerobic glycolysis, a phenomenon termed “the Warburg effect.”

2017年10月20日 · The main difference between substrate level phosphorylation and oxidative phosphorylation is that substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from a coupled reaction whereas oxidative phosphorylation is the production of ATP from the oxidized NADH and FADH 2.

Glycolysis and oxidative phosphorylation (OXPHOS) are two major metabolic pathways to provide energy for cells. Glycolysis converts glucose into pyruvate via a series of metabolic reactions. This process is oxygen-independent, and it is a relatively inefficient way …

2021年11月22日 · Conventionally, there are three energy systems that produce ATP: ATP-PC (high power, short duration), glycolytic (moderate power/short duration), and oxidative (low power/long duration). All are available and “turn on” at the outset of any activity.

2024年10月14日 · Glycolysis vs. Oxidative Phosphorylation: Glycolysis, an anaerobic process, converts glucose to pyruvate to generate a small amount of ATP. In contrast, oxidative phosphorylation, an aerobic process, oxidizes pyruvate and generates a significant amount of ATP through the transfer of electrons from NADH and FADH2 to the electron transport chain.

2008年11月16日 · By using 2-deoxy-D-glucose (2-DG: glycolysis inhibitor) and oligomycin (inhibitor of oxidative phosphorylation), we examined the energy metabolism of various leukemia cell lines.
