IB Cellular Respiration Demonstration Activity
Everyday you and all other organisms consume some sort of energy. Glucose is often the form of energy consumed. Plants, and some bacteria, are able to produce their own energy (glucose). Humans, and most other organisms, unfortunately are not and thus we must obtain energy from some other means. Once consumed, this energy must be converted into forms usable by cells. This, in a nutshell, is the process of cellular respiration and the process we will examine further today.
Respiration in Yeast
Yeast is a simple organism that is often used in biological experiments; more commonly, it is used by bakers to ensure bread rises. Yeast needs energy (glucose) just like any other organism and uses this energy to create energy usable by the organism. This process can be observe by the byproducts of this reaction.
