Fermentation

cellular energetics and measuring the rates of respiration and photosynthesis, explain what cellular respiration and its aspects such as glycolysis, Krebs cycle, and electron transport chain then how each process is involved in producing ATP and why fermentation occurs. This lab had two parts to the experiment. Experiment A analyzed cellular respiration by measuring the production carbon dioxide with various forms of sugar. Experiment B examined the effects of different colors of light has on…

1. Explain how an enzyme works, and how a coenzyme or cofactors may be involved in an enzymatic reaction. An enzyme is a type of protein that is produced by living organism, that also speeds up a chemical reaction without actually being involved in the reaction itself. Reactions occur under mild conditions; enzymes also control the metabolism, by taking out nonspecific side reactions. Enzymes catalyze each step of the chemical reactions in a metabolic pathway. In order for this to happen, all…

In fermentation glucose, or sugar, is converted to acid, alcohol, or gasses. The chemical equation for fermentation is C6H12O6 + 2 NAD+ + 2 ADP + 2 Pi → 2 CH3COCOO− + 2 NADH + 2 ATP + 2 H2O + 2H+. The most common substrate for fermentation is sugar. The purpose of photosynthesis lab was to calculate whether or not aquatic plants need sunlight to use carbon dioxide.…

Shirota strain also known as the Shirota strain. 4. Describe the role of starter culture in the manufacturing of fermented dairy products. The role of this starter culture is to convert sugars such as glucose or lactose to lactic acid during fermentation. Fermentation is a chemical reaction that bacteria perform to breakdown carbohydrates in order to release energy and multiply. They are able to live in our intestines, able to reach the intestine alive and proven scientifically to have a…

identify the Gram + cocci I first performed a catalyst test which produced oxygen bubbles and indicated a positive catalase result. The next test I preformed was a mannitol salt test using a mannitol-salt agar plate and the results showed positive fermentation turning the plate yellow and also positive growth. This led me to conclusion that my unknown Gram + cocci was Staphylococcus aureus. Gram – Rod To identify the unknown Gram – rod I first performed a H2S production test using a…

1)Hands were washed thoroughly with soap and water to ensure that no contamination on the coli-MUG tubes. The sealed plastic package was opened and coli-MUG tubes were removed. 2)Usually, inner fermentation vials contain only air. The assemblies was inverted and inner vials were allowed to fill with air, only if these inner vials contain any liquid. 3)Cap was removed and it was ensured that open end of the tube or the inside of the cap did not open. 4)Each of the given tubes were dispensed with…

Cellular Respiration Cellular respiration is a 3 step process that makes energy. Every organism on earth needs cellular respiration to survive because without energy an organism cannot survive. The chemical formula for cellular respiration is C6H12O6+6O2 > 6CO2+6H2O+38 ATP. So how do runners perform cellular respiration in a race? First the runner must breath in and air goes through the mouth and through the air way to get to the lungs. The lungs then take oxygen from the air and diffuse it…

Introduction The process of beer fermentation begins with a step called malting, which involves soaking various grains (barley, wheat, etc.) in water, increasing the moisture content of the kernel. The grains are then able to germinate for approximately five days which activates proteases, β-glucanase, α-amylase, and β-amylase. Starches and proteins are then made available for cellular processes such as glycolysis and fermentation. Germination is then halted via a drying process…

yellow color change in the lactose fermentation broth would signal a positive result. Bacteria A was able to ferment lactose and displayed a yellow color change as seen in figure 6. Along with the lactose fermentation test, a MacConkey plate streak was performed. This test was not necessary, but it is used to select for Gram-negative bacteria, and can also indicate lactose fermentation. The MacConkey test can be seen in figure 6, however, the results lactose fermentation results are not easily…

MATERIALS AND METHODS The Smith Fermentation Tube was used to determine the effect of the nature of substance on rate of cellular respiration of yeast. Six fermentation tubes were prepared. Each tube was labelled from one to six. 15 mL of solution with 10% concentration were added in the respective tube for starch, lactose, sucrose, glucose, fructose, and distilled water. 15 mL of distilled water and 15 mL 10% yeast suspension were poured to each fermentation tube as seen in Figure 1. All the…
