Observing and Analyzing the Rate of Cellular Respiration in Germinating and Non-germinating Black-eyed Peas
If the cellular respiration rate of germinating black-eyed peas and non-germinating black-eyed peas is compared then the germinating black-eyed peas will have the higher respiration rate.
Organisms need some sort of energy to facilitate their growth and development. Usually, this energy is in the form of adenosine triphosphate, or ATP. Cellular respiration is the process that synthesizes ATP through the three main steps of glycolysis, the citric acid cycle, and oxidative phosphorylation. Essentially, the sugar glucose is obtained by an organism and put through several stages within the three main steps previously mentioned. In oxidative phosphorylation, electrons are passed from a set of proteins called …show more content…
This is evident at the 15-20 minute interval where germinating black-eyed peas has a difference of .60 and non-germinating black-eyed peas has a difference of .10. Figure 1: Respiration Rate in Germinating and Non-germinating Black-eyed Peas
The germinating black-eyed peas has a steeper line than non-germinating black-eyed peas which suggests it had a higher respiration rate.
V. Discussion and Conclusion
The lab and the results gained from this lab demonstrated many important things relating to cellular respiration. It showed that the rates of cellular respiration are greater in germinating peas than in non-germinating peas. The non-germinating peas consumed far less oxygen than the germinating peas. This is because, though germinating and non-germinating peas are both alive, germinating peas require a larger amount of oxygen to be consumed so that the seed will continue to grow and
