was born in 1871 and his name was Ernest Rutherford and he created the Rutherford Atomic model. His “gold foil” experiment was able to disprove JJ Thomson’s Plum Pudding model and prove his own model. His model showed a positive atomic core with electrons floating around the core at some…

an increase in a succinate concentration (a component of the Krebs cycle) will lead to an increased rate of cellular respiration within a cell. We measured the amount of electrons given off by the succinate to fumerate redox reaction by using DPIP. DPIP is an electron acceptor that takes the place of FAD by accepting the electrons and turning from its oxidized blue state to its reduced clear state. We had three tubes with varying concentrations of succinate and measured the transmittance of each…

mitochondria. The third strand of fly used was the sdhBEY12081 strain (mutant) that had a mutation present on the sdhb gene of the mitochondria. The sdhBEY12081 gene is responsible for producing the enzyme succinate dehydrogenase, which is used in the electron transport chain for ATP production. The results showed that the sdhb (mutant) strain of flies developed the quickest, the wild-type strain was second, while the W501 (hybrid) strain had the slowest developmental time. As regards…

To lose these electrons, the electrons are required to travel through the water. Therefore, when we add the iron filings and the water in the jar, it is likely that rust would form after 24 hours. However, the jars that lack oxygen and water (the second and third jars) wouldn’t…

Nobel Gasses goes in this pattern based on the period: 2, 8, 18, 36, 54, 86, 118, .... You can extend it beyond the 7th period: ..., 118, 168, 218, 290, 362, 460, .... The pattern is that the number of electrons…

shares same characteristics and mechanistic features of traditional semiconductor photocatalysis. Through electron harvesting with the help of holes scavenger material and under the appropriate condition, in which in this finding, the appropriate condition is identified as inter-band excitation, higher photon flux, and rapid hole scavenging; a multi electron-holes pair are generated and multi-electron reactions can be driven. Through this finding also, the uses of plasmonic gold NPs as a…

were able to isolate system of electrons and atomic nucleus. The atomic part of physics is primarily concerned with the arrangement of electrons around the nucleus and the processes by which the arrangements was changed. Atomic theory has affected the field of physics in a way that has given scientist knowledge on how to produce an atomic bomb. Scientists has differentiated between atomic physics that deals with the atom as a system involving a nucleus and electrons, and the system that deals…

including hydrogen and helium. Measuring the wavelengths of these emitted spectra will allow us to calculate energies of emitted photons. It is important to note that we will be using the Bohr model of the atom to denote the orbit numbers from which electrons in the sample are relaxing from in hydrogen. This will be important for the conclusions that we will make based upon the calculations using the data collected in the lab. Spectroscopy is the study of how matter and electromagnetic…

It is a part of the respiratory electron transfer chain and the citric acid cycle. During the citric acid cycle SDH oxidizes succinate into fumarate (Hagerhall 1997). SDH in Eukaryotic cells has four subunits encoded by the nuclear genome. SDH catalytic activity is regulated by post-translational…

or nearly the same frequency. Following this experiment, in 1922 de Broglie repeated this experiment, using electrons. When there were two slits, it was expected that the…
