According to the biology department at Georgia Tech, glycolysis occurs in the cytoplasm in eukaryotic cells. This process converts glucose into pyruvic acid though a chemical reaction.
Glycolysis starts with glucose molecules that have been transferred to the eukaryotic cell from the bloodstream to the cell's cytoplasm. The glucose gains two phosphate molecules as it reacts with two ATP units. The resulting molecule splits into two halves. Several chemical reactions convert each half molecule into a pyruvate molecule. As electrons transfer during the reactions, four ATP units form, for a net gain of two ATP units. If oxygen is present, the pyruvate then oxidizes for a larger ATP gain.Learn More
According to the Georgia Tech biology website, fermentation occurs in the cytoplasm of both prokaryotic and eukaryotic cells. Fermentation occurs after gycolysis, which is the breakdown of glucose into pyruvate, and is necessary to regenerate NAD+ molecules so that the cell can continue to make ATP.Full Answer >
According to the University of Maryland, prokaryotic cells are around 10 to 100 times smaller than eukaryotic cells. Prokaryotic cells have a cell wall that is chemically complex. Eukaryotic cells have a very simple cell wall or none at all.Full Answer >
In eukaryotic cells, glycolysis takes place in the cytosol. After glycolysis, the products can be further broken down in the mitochondria.Full Answer >
Cellular respiration occurs in both the cytoplasm and mitochondria of eukaryotic cells. In general, the complete process of cellular respiration is composed of two main parts: glycolysis in the cytoplasm, and the citric acid cycle in the mitochondria.Full Answer >
