We also investigated the regulatory mechanisms underlying energy production in erythroblasts during terminal differentiation under 5% or 21% O2 conditions. The results obtained revealed that the enucleation ratio and intracellular levels of adenosine triphosphate (ATP), lactate dehydrogenase (LDH) M3H, ...
As expected, glycolysis flux is increased in tumours compared with healthy tissues (the Warburg effect2,3), but this increase is insufficient to compensate for low TCA flux in terms of ATP production. Thus, instead of being hypermetabolic, as commonly assumed, solid tumours generally produce ATP...
Cells produce ATP most efficiently in the presence of what? What organelle is responsible for ATP production? What function does ATP serve inside cells? What is the net ATP production in glycolysis? What organelles produce ATP? What can mitochondria directly use to make ATP?
In glycolysis, the hydrolysis of ATP to ADP is used to drive the phosphorylation of glucose: Glucose + ATP ↔ ADP+ glucose-6-phosphate ; Δ G = -17.7 kJ What is the value of Kc for this reaction at 298 K?Determine the ATP yield of the following reaction: Acetyl...
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 ...
A central role of IF1 in cellular homeostasis has been highlighted by the finding that IF1 is overexpressed in human carcinomas, where it exerts a metabolic rewiring to an enhanced glycolysis by activating ROS-dependent signaling pathways and, possibly, by inhibiting ATP synthesis by the FOF1 ...
in neutrophils (Opa1N∆), we report that lack of OPA1 reduces the activity of mitochondrial electron transport complex I in neutrophils. This then causes a decline in adenosine-triphosphate (ATP) production through glycolysis due to lowered NAD+availability. Additionally, we show that OPA1-...

The latter phenomenon is known as 'aerobic glycolysis' and has become a central topic in the field of cancer biology. Aerobic glycolysis is induced by several factors including dysfunction of mitochondria. The cells with the dysfunction of the oxidative phosphorylation (OXPHOS) increase production of...
and many amino acids form intermediates of both theTCA cycleand glycolysis. Any intermediate withdrawn for biosynthesis can thus be readily replenished by the catabolism of further nutrients. This situation does not always hold, however. Microorganisms in particular can derive all of theircarbonand en...
