Whenever I hear the word respiration I think of the word ‘respire’. Respire is breathing, us, as humans we need to breathe. Every time we breathe we take in oxygen and we exhale carbon dioxide. In this lab the topic was about cellular respiration. The lab is to investigate fermentation in respiration. Cellular respiration is a process an organism goes through to obtain energy, ATP [adenosine triphosphate]. Oxygen is then reacted with glucose which results in water, carbon dioxide and ATP. Every organism goes through some type of respiration but only animal cells undergo cellular respiration. For this lab we came up with a question, what environmental conditions are optimum for alcoholic fermentation? What temperature ranges? Our hypothesis was, higher temperature will accelerate the production of carbon dioxide between honey and yeast. …show more content…
In test tube one 8 mL of water and 2 mL of yeast was added to it. In test tube two 5 mL of honey and 4 mL of yeast was added to it. In test tube three 8 mL of water and 2 ml of yeast was added to it. In test tube four 5 mL of honey and 4 mL of yeast was added to it. In test tube five 8 mL of water and 2 mL of yeast was added to it. Lastly, in test tube six 5 mL of honey and 4 mL of yeast was added to it. Each individual test tube was then placed in a larger test tube and inverted. Once inverted test tubes one and two were then place in a water bath at 40C. Test tubes three and four were placed on the lab table at room temperature. Test tubes five and six were then placed in ice. The bubble height in each test tube was then recorded every 5 minutes for 20 minutes
