Oxygen

need water, a food source (glucose), and the right temperature and pH. They are also facultative anaerobe, which means that yeast can respire or ferment depending upon environmental factors. Aerobic respiration will take place if there is oxygen present. Without oxygen present, fermentation occurs (anaerobic respiration). During alcoholic fermentation, the glucose produces carbon dioxide and alcohol. The scientists hypothesized that, if the temperature is higher then the carbon dioxide will…

Plants photosynthesize in order to produce sugar and oxygen, which, in turn, gives the plant energy. Photosynthesis usually tends to occurs more when more chlorophyll are present in the leaves. When the leaves are exposed to light, the process of photosynthesis begins. The more light the plant is exposed to, the quicker the rate of photosynthesis will occur. Altering the amount of carbon dioxide given to the plant can also alter the rate at which photosynthesis occurs. Photosynthesis is a…

Effects of Temperature and Substrate on Catalyst Enzymes Ryan Smith Lab Section 030 Abstract In order to turn hydrogen peroxide into water and oxygen by using enzyme called a catalyst. To determine the effects of temperature and substrate concentrations we preformed an experiment testing the effects on the catalyst enzyme reaction. The hypothesis for our first experiment was if the substrate concentration is larger than the catalyst enzymes activity will be faster as well. The result followed…

derived from decaying plants and animals that have been fossilized over millions of years. There is more to them than that however they are also hydrocarbons comprised primarily of the following elements: carbon and hydrogen and some sulfur, nitrogen, oxygen, and minerals. Different combinations of these elements are used as a fuel for our everyday lives. This paper’s purpose is to explain some of the chemistry behind the use of these various fossil fuels as well as just some general properties…

you know that if the check engine light of your car is on, it indicates the problem in oxygen sensor? The oxygen sensor checks that the fuel injectors gets the gas and air mixture. The fuel injectors then supply the fuel to the combustion process. It helps to increase fuel efficiency. Therefore, if the oxygen sensor is not working properly, the check engine light will be on. It is telling you to repair the oxygen sensor before the emission test. Failing at that, there are high chances that your…

The patient saturation before the change of shift was at 91%. This short term goal was achievable due to clear communication skills the team. The incoming nurses were able to maintain the patient oxygen saturation of at least 90%. The patients pain was well controlled and decreased dreastically within the 12 hour shift. In addition to medication, the respiratory team was able to teach the patient effective ways of using instruments to improve adequate…

This could be resolved by testing the chamber before hand to be certain that there are no gaps in the stopper and the chamber before the experiment is performed. We also struggled with using the graduated cylinder as a measuring apparatus so some oxygen produced may have escaped into the environment instead of into the cylinder. This could be resolved by being prepared for the flip of the chamber and having the cylinder prepped before the flip has even…

temperature service • Appearance • Hygienic • Has a respectable friction coefficient Corrosion resistant Stainless steel has a chromium-rich rust protective oxide thin film on the surface known as a passive layer, in which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1, stainless steel rather than forming a rust layer like other carbon steels, it produces an macroscopically invisible layer in which…

In lab, a sample of crude caffeine was purified using the technique of sublimation. Thin layer chromatography (TLC) was used to verify the caffeine's chemical structure and purity. Sublimation played a huge role in the purification of the crude caffeine. The process of sublimation is to take a chemical and change it from a solid phase directly into a vapor. Another reason as to why sublimation was used is because the caffeine can be separated from its contaminant due to the fact that it does…

an Athlete takes part in acute exercise, the musculoskeletal system responds in a number of ways. The muscles increase in temperature and metabolic activity as a short-term response to acute exercise and this accordingly increases the demand for oxygen, a demand that is met through capillary dilation to increase blood supply. The muscles warm during any form of exercise as to make them more pliable and so to reduce any risks of injury; this is known as an increase in muscle pliability. Movement…
