  • His experiments involved measuring the multiplication of yeast and the rate of alcohol production. He found out that the fermentation rate and the reproduction of yeast were directly proportional. Alcohol was produced as long as the yeast remained alive.
  • Therefore, through experimentation, Louis Pasteur demonstrated that only microorganisms could ferment sugars into alcohol.

Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms  have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.

They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.

They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.
