Cellular Respiration Lab Report
Calculation Process:
The rate of respiration is calculated by dividing the distance that the drop of dye moved over 5 (period of time). For example, at 19 OC, the distance that the drop has moved after 5 minutes for the 3 trials are respectively 0.19, 0.10 and 0.13. The rate of trial 1 is then calculated by dividing 0.19 over 5, which is 0.0380 (shown above). For average rate of respiration, it is calculated by adding up all 3 trials of the same temperature and dividing the sum by 3. Additionally, for the standard deviation, it is calculated in the google sheet (or excel) by placing the number of all 3 trials of the same temperature in the sheet.
Data Processing- qualitative data
There were a few qualitative measurements during the cellular respiration reaction. Through observation, some vials are misty and some are clear. One of the products in the cellular respiration reaction is water, therefore the water vapor is condensed around the vial, which created the misty look. However, some reactions hadn’t reached that process yet, thus the vial had still remained clear.

This hypothesis was supported in the data recorded and final graph shown above. The final graph has a polynomial trendline, which has a resemblance trend as the graph in the hypothesis section. Moreover, it has shown that the highest temperature (39 OC) had the greatest rate of cellular respiration and comparatively lower rate at 19 OC. By theory, temperature higher than 39 OC would have denature the enzymes resulting to a decrease trendline as there is no pressure being
