Hypotheses: • Aerobic: If succinate is added to certain test tubes, then the percent transmittance of the mixtures in those tubes will increase. This is caused by the resulting higher oxidation states making DCPIP bluer, no due to the amount of mitochondrial suspension. • Anaerobic/Fermentation (A): If the temperature is greater than or less than room temperature (21.11ºC/294.26 K), then the difference in final volume from initial volume will be positive and larger than room temperature. However, after a certain temperature, the values of the difference between final volume and initial volume will start to decrease. • Anaerobic/Fermentation (B): If the alternative sugars are heated at a constant temperature of 45ºC (318.15 K), then some of …show more content…

This process can be performed in two stages: aerobic (presence of oxygen during process) and anaerobic (no presence of oxygen during process). During aerobic cellular respiration, the process uses the products from the glycolysis cycle, Krebs (citric acid) cycle, and electron transport chain. During anaerobic cellular respiration, the process only uses the products from the glycolysis cycle and fermentation, which is split into either lactic acid process (in muscle cells and produces lactate as byproduct) or alcohol process (happens with yeast products, and causes NADH to donate electrons to pyruvate and convert it into …show more content…

During the second experiment, it was observed that test tube 2 at room temperature did not have a change in volume. In similar fashion, test tube 5 did not have significant change in the volume, only adjusting by +0.4 mL. In the ice (0˚C), test tube 1 had a change of 1.3 mL, while in warmer temperatures above room temp. and below 100˚C had changes upward of 3.5mL+. The reasoning behind this is that since these processes are enzymatic, the enzymes work productively in a certain temperature range. When reaching extreme or baseline temperatures, the enzymes slow down their process (i.e. tubes 2 and 5). The hypothesis is supported, however, it does not give a more detailed interest as to what temp. range works best. In the experiment, it was determined that the ideal temperature was
