Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process. It occurs in the cytoplasm of cells and is essential for cellular energy production.
congrats on reading the definition of glycolysis. now let's actually learn it.
Glycolysis is the first step in both aerobic and anaerobic respiration.
The process produces a net gain of 2 ATP molecules per molecule of glucose.
Glycolysis is crucial for brain function as neurons rely heavily on glucose for energy.
It involves a series of ten enzyme-catalyzed reactions.
In neurological conditions like Alzheimer's disease, glycolytic pathways may be impaired, affecting brain metabolism.
