The purpose of this experiment is to observe the formation of CO2 in varying concentrations of yeast and glucose and adding heat in an anaerobic environment. Place the 1.0g of sucrose onto the 5 cm x 5 cm x 1cm paper container 13. Another issue in the lab that could have affected the results was inconsistent swirling of the flask before each measurement of pH level. This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown. The energy stored in chemical bonds of glucose and other food molecules needs to be released and converted into a diffusible, usable form ATP. A major error in the lab was the pH probe during the experiment was up to high in the Erlenmeyer flask and this effected the pH we got due to a number of factors inside of the flask that could have changed the pH. The usefulness of fermentation as a means of deriving energy is limited because. Connect Master If the living organism is placed in a closed system with the carbon dioxide removed as it is produced, then the consumption of oxygen can be determined using a respirometer.
