Adenosine diphosphate

reproduction. The nuclei also will pellet after the 1st low speed of the centrifugation, which can be seen under a microscope. Mitochondria has a low dense organelle that has a double membrane, allowing oxidative phosphorylation. Generates the majority of adenosine triphosphate known as ATP, for energy. The pellet will be formed after the 2nd centrifugation; the absorbance measured of the mitochondria will be low. Succinate dehydrogenase (SDH) is an enzyme located in the mitochondria membrane.…

Touch football is a physically demanding sport requiring the extensive use of many systems of the body. It is important for an athlete to properly train and develop these energy systems to perform to their highest potential. I have constructed a training program in order to develop upon my two weakest areas, muscular power and the combination of speed and agility. The average to poor results I received during fitness testing reflected my performance in the vertical jump test, 40m sprint, and the…

Cellular respiration is “the catabolic pathways of aerobic and anaerobic respiration, which break down organic molecules and use an electron transport chain for the production of ATP” (Campbell G-6). The chemical equation for cellular respiration is C6H12O6+6O2→6CO2+6H2O+energy. During that multi-step process, organic molecules are oxidized and catabolized down to carbon dioxide. The energy that is released during this breakdown is captured by the electron carriers, which is any of various…

P450-GloTM bioluminescent CYP assay Three concentrations of PTV (1, 10, 100 µM) were conducted to detect the luciferin PPXE activity against recombinant CYP3A4 and CYP3A5. A significant decrease in the luminescene activity in both recombinant CYP3A4 and CYP3A5 was observed in 10 µM and 100 µM of PTV (Fig 1). It seems that PTV is a candidate drug for metabolism against CYP3A4 and CYP3A5 enzymes. Metabolite profiling and Identification After incubating PTV with HLMs in the presence of a NADPH…

The article “ When Did Photosynthesis Emerge on Earth?” was written by the principal investigator of the Ames Research Center team of the NASA Astrobiology Institute, David Des Marais. His experience has led him to publish more than 160 technical articles and chapters on many research topics such as the biogeochemical carbon cycle and the early evolution of the Earth and its biosphere. In this particular article, Des Marais establishes that life dates back to 3800 years ago and that not only…

Methods Each trial consisted of isolating the hearts of two mice, aged anywhere between 8-15 weeks, with the strain FVB/NJ of the Mus genus. Eight trials were conducted throughout the duration of the experiment. No female mice were used for any of the trials because because the research in the lab concentrates on males, due to known differences in protein expression among the two sexes. The effect of the VU591 drug on mitochondrial KATP function in wildtype mice was measured by calculating the…

All living things need to go through cellular respiration to convert sugars into energy. While this process usually involves oxygen, a type of respiration called fermentation does not (which is why it�s also called anaerobic respiration). Humans have long known about fermentation for use in bread and beverages, but have recently harnessed this for making fuel. One of the products of fermentation is ethanol, a kind of alcohol. Another is CO2, which can be measured to determine the rate of yeast…

Cell respiration is affected when the heart stops. Cells are using up ATP. Therefore, carbon dioxide is building up in the cells and the PH levels cannot balance themselves. Glucose is needed to start glycolysis. Glycolysis is a series of chemical reactions that produces ATP from the glucose. Oxygen is needed for the mitochondria. The mitochondria are referred to as the powerhouse of cells. Carbon dioxide is not being released. The cells begin to die and the transport pump then stops working.…

The Effect of Time (Seconds) on the Number of Times a Hand can Squeeze a Clothespin Background Information: Cellular Respiration is the process in which glucose is broken down to produce water molecules and ATP. which stands for adenosine triphosphate, is the only usable form of energy that can be used to fuel the activities and life processes of any organism. There are two main types of cellular respiration: aerobic respiration, and anaerobic respiration. The chemical equation for aerobic…

The purpose of the cellular metabolism lab is to determine the effects of inhibitors and other variables on the rate of metabolism in the Krebs Cycle. Inhibitors compete with the substrate to bind to the enzyme, thus slowing down the production of FADH2. When the production of FADH2 is slowed down, the reaction will proceed too slowly for metabolic purposes. In this lab, the enzyme that was catalyzing the reaction was the bean extract. To mimic the FAD that is used in the Krebs cycle, we used…
