Do yeast have mitochondria
WebYeast have mitochondria and can perform cellular respiration. What would you expect to be consumed and produced during the process of cellular respiration in yeast? Glucose and O2 consumed; CO2,H2O, and energy produced. Glucose, H2O,CO2, and energy consumed; O2 produced. CO2 and H2O consumed; glucose, O2, and energy produced. WebThese reactions produce ethanol in yeast, and lactic acid in mammalian cells (muscle cells under oxygen deficit and most tumor cells – see Warburg effect below). Ethanol fermentation regenerates NAD+ from NADH by releasing CO2 from pyruvate and reducing the two-carbon acetaldehyde molecule to ethanol.
