Cellular Respiration Aerobic Cellular Respiration is the process by which the cells in our body get energy to carry out their functions. Cellular respiration is necessary for all living things due to the fact that living things are made up of cells and all cells need energy to carry out their functions. It takes place in the mitochondria of mainly eukaryotic cells. Mitochondria are considered the powerhouses of cells due to their high folds of energy. During aerobic respiration, oxygen is always

assess the relationship between amylase concentration and average starch consumption in ancestral diet. I had hypothesized that due to my South Asian descent I would have a moderate number of AMY1 gene copies and a moderate salivary amylase concentration. This hypothesis was based on the data presented by the Perry et al paper Diet and the evolution of the human amylase gene copy number variation, which claimed that ancestral starch diet influences the AMY1 gene copy number and that gene copy number

INTRODUCTION: Lipase also called as triacylglycerol acylhydrolaseis an enzyme known for its enormous applications for industry and diagnostics. Their basic activity is to convert fats into fatty acids and glycerol. These enzymes are water soluble in nature. They also convert polar solvents into more lipolytic substances. In 1856, a scientist name claude Bernard has identified lipase [1]. Lipases are serine hydrolases containing G-X1-S-X2-G sequences as the catalytic part of the particle, where G

Complete the Chemistry of Pectin lab exercise and then answer the following questions. 1. What is the difference between jam, jelly and fruit preserves? The three points of differentiation are the type of fruit, how it is prepared and the proportion of ingredients. Jams are made of crushed fruits which are cooked with pectin, sugar [and maybe lemon juice to change the pH and cause the jam to become more solid] until the mixture thickens to spreadable consistency. In the lab, we made jam using 500

“Simplicity, Simplicity, Simplicity”: Thoreau’s Way of Life In “The Bean Field” chapter of Walden, Henry David Thoreau retells how he tilled the soil to farm his beans. The first year, Thoreau describes how he plants “about two acres and a half of light and sandy soil” (46). In this soil Thoreau plants beans, potatoes, corn, peas, and turnips. Rising long before the “sun had got above the shrub-oaks” (132) Thoreau levels the haughty weeds barefoot in the dew soaked soil. On this soil, Thoreau abstains

The Effect of the Molecular Weight of a Substance to its Rate of Diffusion Paulo E. Garcia Group 2 Sec U-7L October 16, 2014 ABSTRACT The rate of diffusion was tested by using a petri dish with agar-water gel and three drops of different solutions. These solutions were observed for thirty minutes and measured every three minutes. The different solutions used are Potassium permanganate with a molecular weight of 158 g/mole diffused the greatest distance among the three, Potassium

INTRODUCTION Emulsifying agents are substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion. Foods that consist of such emulsion include butter, margarine, salad dressings, mayonnaise, and ice cream. Emulsifying agents are also used in baking to add the smooth incorporation of fat into the dough and to keep the crump soft. Emulsifying agents used in foods include agar, albumin, alginates, casein, egg yolk, glycerol monostearate, gums

Notre Dame University (Louaize) Faculty of Engineering Department of Civil & Environmental Engineering CEN 465 Environmental Engineering Laboratory Lab # 1 Temperature and Water Content Measurement Prepared by: Michella Dib Submitted to: Dr. Yara Medawar February 7, 2018 Part 1: Results This experiment was done by measuring temperature and moisture content of random soil directly below the surface and deeper. No equations were used along the session (No calculation was done). The results

Oleander Soup, Mmmmmm . . . Bitter We expect powerful medicinal agents to taste bad, and oleander soup is no exception. It’s the bitterness of “natural chemotherapy”, and it’s critical to begin slowly. If you experience side effects (like I did), discontinue until you feel better, and don’t make the mistake of thinking it’s going to kill you, so resume once you feeling better. Some substances that are dangerous to cancer can cause you to feel uncomfortable temporarily. You can go to Cancer Tutor

Depending on the processing methods employed to produce them, commercial pet foods fall into one or the other of the following two categories: heat-treated and raw. So-called 'heat-treated ' pet foods are processed using all-too-often excessive levels of heat. These foods are baked, cooked (canned), extruded, or heat-dried (often the case with kibble- or pellet-type pet foods). Diets based on such heat-treated pet foods are probably the least desirable in terms of maintaining the health and general

Yeast is alive because it can to metabolize and respond to environmental changes. The purpose of the first experiment was to determine whether yeast can metabolize. The bromothymol blue solution with yeast changed from blue to yellow. Bromothymol blue is an acid-base indicator that turns yellow in the presence of acid. The color change indicates that carbonic acid was formed from the reaction of water and carbon dioxide, a byproduct of metabolization. These results accept the hypothesis: if yeast

Dark brown sugar is important for both color and flavor in many recipes. Its flavor is versatile and can complement everything from barbecue rubs for meat to gingerbread. You should certainly do your best to keep some on hand at all times. If you run out of dark brown sugar, there are a few alternatives that will be just as effective. Your Best Bet: Make Your Own Dark Brown Sugar Dark brown sugar is white sugar with 6.5 percent added molasses. You can use light or dark molasses for this, but not

Today, Erin and I will be teaching all of you how to make oobleck. And for the people who may not have known this, oobleck got its name from a childrens book called Bartholomew and the Oobleck. In the book, a gooey, green substance fell from the sky and wreaked havoc over the kingdom. To make oobleck, you 'll need your utensils. There isn 't many so don 't worry. The utensils you 'll need are; a spoon, a large bowl, and a measuring cup. Next, you need to gather all of your ingredients. There

The Effect of Varying Temperatures on the Breakdown of Starch in Bacterial Amylase and Fungal Amylase by Grace Ramirez 5869802 Biology 1010 U46 October 26,2015 Lab Partners: Brian Alex Madelin ABSTRACT The purpose of this lab was to test the effects of temperature on bacterial amylase, Bacillus licheniformis, and fungal amylase, Aspergillus oryzae, and ultimately find their optimum temperature at which it breaks down starch to maltose. The Bacillus licheniformis and Aspergillus oryzae

Analysis Conclusion Based of the data collected from the experiments, cornstarch was identified as the unknown powder in the black bag. Cornstarch shares similar chemical properties compared to the unknown powder. They both have a pH of 7, contain starch, but not carbonate, and react with the flame to create a temporary bright orange. Even so, powdered sugar also has the same chemical properties. However, when the powders were viewed in the Scanning Electron Microscope, the powdered sugar grains looked

Are Bananas Worth the Cost? Bananas are cheap and nutritious but did you know the true story behind bananas? Bananas go through a complex system to get to how they look at grocery stores. Moreover, buyers don’t look to see the process behind the production. Workers go through long hours of harsh conditions to get these bananas in grocery stores. Bananas are a staple need for countries. Without the workers, there are no bananas. The mistreatment of the environment is hurting the world and the community
