Yeast cells are added to sterilized corn mash in large industrial fermenters to produce ethanol, which is added to gasoline. It is necessary to install cooling systems around the fermenters because       heat is released at each step of the fermentation pathway   heat is absorbed by yeast as they carry on fermentation   cooler temperatures decrease the production of the CO2 by-product   ethanol is less toxic to yeast at cooler temperatures

Oogenesis

The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
