have theorized that mitochondria evolved from aerobic heterotrophic bacteria undergo symbiosis with primitive eukaryotic anaerobes. Bacteria and mitochondria are structurally and functionally similar in that they are roughly the same size, reproduce by similar means and contain histone-bound DNA. They also contain the tRNAs and ribosomes needed for translation and transcription, and also show some rRNA base sequencing similarities. Additionally, the interior membranes of mitochondria have electron transport
The purpose of this lab was to determine if mitochondria was present in either the supernatant or pellet of a cell. I hypothesize that due to mitochondria being diminutive, they will be present in only the supernatant. For this experiment, I predict that the test tubes with the pea and carrot supernatants will appear to have a reddish tint to them. Five test tubes were labeled A-E. Two of the test tubes were filled with the remaining supernatants, another two were filled with the remaining pellets
Electromyography (EMG) and Human Nerve Conduction Conducted by: Stephanie, Julian and Renee (Group J16) Aims: Introduction: By placing recording electrodes on the surface of the skin that overlies the target muscle, it is possible to detect and record the electrical activity of the nerves. This is done by performing an Electromyography (EMG) and according to Alan (1988), from these recordings we can determine the conduction velocity of the nerve. Conduction velocity is the rate of transmission
