Emergency Room

The procedure taken at my last emergency room visit took many steps. The evening began by entering in to an overly crowded waiting area. Every chair that lined the walls was filled with a warm body, many of whom where hacking, coughing, sneezing and such. I approached the registration window and was greeted by a kind intake worker who proceeded to evaluate my situation. He then sent me around the corner to have my vitals taken and registration paper work…

Nutrition and Body

All macromolecules are essential to the body. One has to have the right amount of all of the macromolecules in order to be healthy. It is believed that high protein diets with carbohydrate restriction causes weight loss. However as a result of high protein diet, one damages his/her kidney which is responsible for filtering proteins from blood. In the article, Janine says, “If you eat too much proteins and not enough carbs you can ruin your kidneys forever.” I agree…

Energy Drink Lab Report

As a result of conducting various qualitative chemical analysis tests, Monster Energy ® was found to contain a large amount of reducing sugars and NaCl. It was found to be void of proteins and lipids. Further, Canada Dry ® gingerale was found to contain a large amount of reducing sugars, while being void of protein, lipids and NaCl. The components of the Monster Energy drink tested were quite congruent to the components found in the other energy drinks. The exceptions,…

Hereditary Fructose Intolerance

Enzymes are proteins that increase the rate of chemical activity. Their three dimensional structure determines their function, and is made of chains of amino acids that have folded into a specific shape with a unique property. Enzymes lower the activation energy needed for a chemical reaction, therefore speeding up the process. Multiple enzymes work together in metabolic pathways, taking a product (end result) of one metabolic reaction as a substrate (substance or molecule at start of process) for another reaction….

Cellular Respiration

Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is a way cells store food and energy, a catabolic pathway for the production of adenosine triphosphate (ATP). The cellular respiration happens in both eukaryotic and prokaryotic cells. The three stages are Glycolysis, Citric cycle, and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis splits the sugar that goes…

Why Are Proteins Important

Proteins can easily be addressed as one of the most important molecules in animal cells. There are many varieties of protein molecules which allow a vast range of biological activities in the cell.( Williams, G.(2000))’Proteins are big compound with large molecular masses”(Williams, G.(2000)) whose main chemical constituents are hydrogen, carbon ,oxygen and nitrogen. A protein structure consists of a specific sequence of amino acids called the primary structure, this particular sequence determines the secondary structure of the protein which can…

The Effect of Temperature on the Rate of Yeast Respiration

Abstract Carbon dioxide is a waste product of yeast respiration. A series of experiment was conducted to answer the question; does temperature have an effect on yeast respiration? If the amount of carbon dioxide is directly related to temperature, then varying degrees of temperature will result in different rates of respiration in yeast. The experiment will be tested using yeast and sugar at different water temperatures. I predict the warm temperature will be optimal for yeast respiration therefore the most…

Cellular Respiration and Photosynthesis

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However, in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration, we need to understand what is photosynthesis and cellular respiration and examine each of…

Metabolism_ Cellular Respiration and New World Encyclopedia

Enzymes are molecules that are responsible for chemical reactions that occur within the body. They act as catalyst by accelerating metabolic reactions from the digestion of foods to synthesizing deoxyribonucleic acid (DNA). An enzymatic reaction changes substrates, the beginning molecule, into products. Enzymes are selective for the type of substrate that they will bind to; they have specific shapes that fit into one another like a lock and key as illustrated in figure 1 and 2 below. Enzymes (Figure 1,…

What Chemical Compounds Does the Human Body Consist Of_

Oxygen (65%) and hydrogen (10%) are predominantly found in water, which makes up about 60 percent of the body by weight. It’s practically impossible to imagine life without water. Carbon (18%) is synonymous with life. Its central role is due to the fact that it has four bonding sites that allow for the building of long, complex chains of molecules. Moreover, carbon bonds can be formed and broken with a modest amount of energy, allowing for the dynamic organic chemistry…

Anatomy & Physiology

In this assignment the concept of homeostasis will be explained and the probable homeostatic responses to changes in the internal environment during exercise will be discussed. Homeostasis is simply how the body keeps conditions inside the same. It is described as the maintenance of a constant internal environment. Generally, the body is in homeostasis when its needs are met and it’s functioning properly. Every organ in the body contributes to homeostasis. A complex set of chemical, thermal, and neural factors…

Health Write Up Alcohol

Alcohol is one of the most abused drugs in America. It is easily accessible, cheap, and perfectly legal to buy and consume. The way alcohol works is that it enters your bloodstream and moves into the biological membranes in your body. Up to 20% of alcohol consumed is absorbed through your stomach lining and 75% is absorbed in your upper intestine directly into the blood stream. Absorption rate is increased if you mix with carbonation, it is decreased with food,…

The Building Blocks of Life Worksheet

Part 1: Mitosis and Meiosis Short-Answer Response Use Ch. 5 of BioInquiry and the “Comparing Mitosis and Meiosis” video as resources for Part 1 of this assignment. Write 75- to 100-word answers to the following questions. Why are the process of mitosis and meiosis both important to a living organism? Mitosis is the process of asexual reproduction of cells. This process is important in order for living organisms to continue to live. If mitosis didn’t happen the living organisms would…
