Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

organic molecules are carbohydrates‚ lipids‚ and proteins. Carbohydrates contain carbon‚ hydrogen and oxygen with a ratio of 1:2:1‚ this means that for every 2 hydrogen atoms there is one carbon atom and one oxygen atom. They are necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides are made

grandma turns the TV off. Why does she have to cry because of the big screen things. Moreover‚ my niece also acts aggressively toward people in the house. At first‚ I thought this was so ridiculous that she cried because she was not allowed to watch TV. However‚ after I saw these situations regularly‚ I realized this was not funny anymore. Is there any way that I can help my niece to get rid of spending too much time with TV? I was really curious about how TV affects children‚ so I typed it into

well. Being homeless takes away the sense of belonging that humans need and often causes self-esteem issues and a sense of helplessness. Those who are homeless often suffer depression and anxiety or behavioral problems. This contributes to the higher rates of drug use among homeless people and creates a positive feedback loop in which they use drugs to combat their situation which only worsens it. In addition‚ homeless people have a higher risk of

Lactose Intolerance is an intestinal condition caused by insufficient synthesis of the intestinal enzyme lactase needed to break down lactose (Keith‚ Nichols‚ Reed‚ Kafer‚ Miller 2011). So what does this exactly mean? People with lactose intolerance have trouble digesting lactose‚ the natural sugar found in milk and milk products. Undigested lactose can upset the stomach and cause diarrhea. Most people who are lactose intolerant are able to consume some lactose without symptoms. However‚ many people

Fermentation of a Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure

Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose Brandon Bosley BIO 121 11/19/2013 Introduction: In our lab this week we tried to see how different amounts of substrates affect our organism‚ yeast‚ in its fermentation process. Yeast (Saccharomyces cerevisiae) is an organism that is cultured for the cells themselves‚ as well as the end products that they produce during fermentation. Yeasts are commonly known for the ethanol fermentation due

According to Vivaxmalaria.com “Plasmodium Vivax occurred in macaque monkeys in the south-east part of Asia when it started spreading to Africa and to humans.”2 and then migrated to other countries in Africa. Most types of Malaria started with an animal infection and then spread to humans .Historical references of Malaria include a writing in a Chinese medical paper and ancient egyptians wrote written accounts of the symptoms of Malaria but the first real case of

INTRODUCTION Cellular respiration is a biochemical pathway in which cells produce ATP or energy and carbon dioxide as metabolic waste by breaking down the chemical bonds of food molecules. Cellular respiration is a type of aerobic respiration which needed oxygen in order to produce ATP which occurring in the mitochondria. Meanwhile‚ in the absence of oxygen‚ the cells will undergo anaerobic respiration to produce ATP in the cytoplasm. Anaerobic respiration can be divided into two parts which are
