Oxygen

to neutralize the hydrogen chloride produced in the reaction. The lone pair of electrons on the nitrogen atom performs a nucleophilic attack on the carbonyl carbon, while a pair of electrons in the double bond is pushed to the oxygen atom. When an electron pair from the oxygen atom restores the double bond, the chloride ion will act as a leaving group. The nitrogen atom is deprotonated by a chloride atom, forming N,N-diethyl-m-toluamide. One interesting note is that after the addition of thionyl…

The remains of the plankton the algae have feasted on falls to the floor where they are consumed by bacteria. These bacteria are what cause the waters to turn hypoxic. The large amounts of bacteria that are now located in the water, consume all the oxygen therefore leaving…

off is used to release ATP during cellular respiration. 2. The splitting of water during the light reactions of photosynthesis in Photosystem II produces oxygen that releases into the air as carbon dioxide. The oxygen from this is used in glycolysis which is the first stage of cellular respiration as it combines oxygen and glucose. 3. Oxygen is a by-product of photosynthesis which is used as a final electron acceptor in aerobic respiration in cellular respiration. 4.…

chemical reactions, firstly there's synthesis, (e.g. 2Na + Cl2 → 2NaCl); then, the other type of reaction is decomposition (CaCO3 → CaO + CO2); and finally there is combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types of reactions, bonds are broken and then formed to create the end product, which all requires the use or release of energy. To observe the way the…

and molecules combine to make macromolecules. Carbohydrates Carbohydrates are molecular compounds made from just three elements: carbon, hydrogen and oxygen, usually in a ratio of 1:2:1. Monosaccharides (like glucose) are relatively small molecules. They…

Unlike oxygen and water, food is possible to manufacture in situ on the way to mars or farther celestial bodies. Historically, it has not been general practice to grow food in space because there has never been a need to. The Apollo missions were brief enough that…

Diabetes mellitus is a chronic metabolic disorder that affects millions of people in the United States. There are two types of diabetes, and type 2 is the most prevalent type at 90% of all cases. Different from type 1 diabetes, which is a complete need for insulin replacement, type 2 diabetes is caused by a resistance to insulin made by the pancreas as well as a deficiency in insulin. This resistance and deficiency is usually caused by lifestyle risk factors including body weight, diet, and…

addition, water allows people to grow their crops and food in order to consume them later on and gain energy as well as other important nutrients from them. Not only does water help crops, but it also helps other important plants and trees produce oxygen for organisms to breathe. Also, at times water can help clean things such as clothes and cuts, this is very important because it can help prevent the spread of diseases and illnesses in many ways. Considering how water covers up more than…

color chlorophyll and produces oxygen as a result (What is Photosynthesis, P.1). Plants also use photosynthesis to create sugar. The sugars fuel a plant's roots, stems, and leaves so the plant can grow. It attempts to preform photosynthesis with leaves absorbing the sun’s light and then make the sugars within the chlorophyll located in the plant as shown in figure 1. After plants use the Sun's light to make their food (sugar), plants release oxygen into the air. The oxygen is very important…

darkness falls, but this is not true. There are metabolic processes that continue. The process of Calvin cycle, enables a plant to capture carbon which is stored and used as energy at night. Oxygen is also another important aspect and plants produce oxygen during the day due to photosynthesise reactions and use oxygen at night due to respiration. Plants are very intelligent in that they anticipate the coming of dawn and prepare for it on a cellular level. To conclude, darkness does play an…
