    Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

    Report Measuring Reaction Rate using Volume of Gas Produced By John Doe 23th October 2012 Introduction An essential element of chemistry is finding reaction rates. This is because chemists need to know how long a reaction should take. In addition to needing to know the rate of a reaction at any point in time to monitor how the reaction is proceeding. Many factors effect reaction rates‚ two shown above include temperature and concentration. Concentration affects the rate of reactions because

    Cellular Respiration Purpose The purpose of this experiment was to determine the effect of body mass and temperature on the rate of respiration in the mouse. Hypothesis When the temperature is reduced‚ cellular respiration will increase. Measurement Weight the mouse and use soda lime for mouse to perspire. Oxygen was inhaled and carbon dioxide was exhaled. Carbon dioxide was absorbed by soda lime. Rate of respiration was measured in terms of ml of oxygen per min over grams. General

    Drug Testing To Receive Welfare Welfare is a tax payer sponsored program that gives financial benefits to underprivileged families. With a sizable number of families using the government issued money to fuel their substance abuse‚ naturally this would spark an outrage from the tax payers and politicians. Drug testing recipients of welfare is currently the only reasonable solution to pacify the controversy at hand. The idea of drug testing welfare recipients before and during their receiving of

    body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it is called enzymes- substrate complex‚ and after the enzyme finish catalyzing‚ the substrates before is turned

    ATP are cellular respiration and fermentation. (Hyde‚2012). Fermentation is a way of harvesting chemical energy that does not require oxygen. (Reece et al. 2012). When the body is deprived of oxygen it will then begin to meet its energy needs through the slow process of fermentation. In our lab we investigated alcoholic fermentation by using yeast‚ which can flourish in an low energy environment in anaerobic conditions. In this lab our goal was to discover the rate at which yeast will ferment different

    Finding the Optimal pH of the Enzyme Peroxidase with the Aid of a Spectrophotometer ABSTRACT The peroxidase enzyme was partially purified‚ and the enzyme activity was calculated with the use of a spectrophotometer‚ demonstrating the effect of pH on peroxidase activity. The objective of this exercise was to determine the ideal pH for peroxidase activity. The data concluded that the optimum pH for peroxidase activity is 5‚ and the “standardized” enzyme volume is 2.8mL
