Cellular Respiration with LabQuest
O'Bryant - January 28, 2021
Experiment 1:
Question: How does the length of germination time effect the rate of CO2 production in alaska peas?
Independent Variable: Germination Time (Un-germinated, 24 Hours, 48 Hours)
Dependent Variable: CO2 Production
Experiment 2:
Question: How does rate of CO2 production compare between Soy Beans, Mung Beans, and Alaska peas?
Independent Variable: Type of pea/bean (Soy Beans, Mung Beans, Alaska Peas)
Dependent Variable: CO2 Production
Experiment 3:
Question: How does rate of CO2 production compare between equivalent masses of Crickets and Alaska Peas?
Independent Variable: Organism (Crickets, Alaska Peas)
Dependent Variable: CO2 Production
Line of Best Fit and Calculating the Respiration Rates
In order to determine the respiration rate for each of the variables tested above, we must calculate the line of best fit for each dataset.
Recall, a linear equation has the form Y = mx + b
| Condition | Respiration Rate (CO2 ppm/second) |
| Un-germinated Alaska Peas | -0.008142835141 |
| 24 Hour Germinated Alaska Peas | 0.400294823 |
| 48 Hour Germinated Alaska Peas | 0.3947037469 |
| 24 Hour Germinated Mung Beans | 0.3296257508 |
| 24 Hour Germinated Soy Beans | 0.3539077248 |
| Crickets | 1.477949 |
