ISOLATION OF PURE CULTURES

Exposure of sterile media to the environment will demonstrate the importance of aseptic technique. 1. Label two nutrient agar plates as "Exposure I" and "Exposure II." 2. Uncover the plate marked "Exposure I" and allow it to remain exposed in the lab for about 5 minutes. 3. Expose the plate marked "Exposure II" to a source of possible contaminants.

Blow Up a Balloon with Cellular Respiration

oxygen present, fermentation occurs (anaerobic respiration). Both processes require sugar to produce cellular energy. Here is the chemical reaction of fermentation, which produces ethanol and carbon dioxide as metabolic waste products. Objective: In this lab, students will use the respiration powers of yeast to blow balloons. This

Lactic acid fermentation

Fermentation, however, is far less effective than cellular respiration, producing only two ATP molecules per glucose molecule consumed. The typical yield from cellular respiration is anywhere from 34-38 molecules of ATP. Thus, it is typically seen only in small organisms, such as bacteria and yeast, that can survive on this low energy yield.[4]
