In order to understand hypercholesterolemia and hyperlipidemia an understanding of what cholesterol and lipids mean and do for an organism. Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins, hormones and most of the non-protein membrane of cells. Lipids are insoluble and nonpolar there for are not soluble in water. Fatty acids are long chain carboxylic acids (typically

ABSTRACT: This experiment was to observe diffusion happening within the cells, and to help understand the sizes of molecules and how the chemical reactions take place. Therefore, the experiment was conducted using glucose and starch solution inside the dialysis tube. The starch and glucose that was put inside the dialysis tube help identify which of the two will reacted with potassium iodide inside the breaker, as the latter passed from the beaker into the tube, the glucose/starch solution's change

ascertained the underlying response speed of the concoction response and confirmed that pH 7.0 was the ideal pH for this compound response since it had the most elevated IRV. INTRODUCTION: Enzymes are very unique and important to the well being of humans,

on the ways enzymes work. It also will give information on the role of substrates and how it affects enzymes. In the first experiment, we examined whether or not the speed of the reaction will be influenced positively by an increase of heat to a point where it will not be denatured, but negatively by a decrease of heat. In the second experiment we looked to see if the speed is influenced positively by an increase of enzymes to a point, but negatively affected by a decrease of enzymes. For the third

1. What is the definition of a cytokine? Cytokines are a group of the multi-functional protein. In general, cytokines are produced by immune cells to communicate and operate the immune response mechanism. The cytokines are produced by different cell types, including lymphocytes (T and B), monocytes, and eosinophil. The cytokine binds to a specific receptor on the membrane for their target cells trigger the signal path inside cells and eventually lead to change gene expression of the target cell

Enzymes are fundamental proteins which act as effective catalysts for biochemical reactions within an organism. Enzymes are distinct from one another; they attach themselves to specific slots on substrates called active sites to lower the activation energy to start the chemical reaction. This is represented by the lock and key model, where the shape of the enzyme directly corresponds to the substrate to carry out a specific job. An enzyme is able to be used until it becomes denatured, or when the

Enzymes are proteins that are made by living cells. They act as catalysts, speeding up the chemical reaction process, remaining unchanged before and after. They do so by lowering the activation energy, meaning when they are present, less energy is required for the reaction to occur. The enzymes act on a substrate during the process. A substrate is any compound the enzyme bonds with. However, the substrate must match a specific shape for the two to bond properly. This is known as the key and lock

Abstract Enzymes are proteins produced by living cells. In an enzyme, the substrates bind with the active site of an enzyme, breaking them down into other molecules. Enzymes acts as catalyst which lower the reaction energy and allows it to take place in less time and at lower temperatures. Enzymes can be used in a reaction without actually being used up; therefore, they can be used reversibly. Temperature, salt concentration, substrate concentration, enzyme concentration, and pH can affect enzyme reactions

out these actions? Enzymes play a huge part in cellular activity, as was discovered in 1896 (Human Touch of Chemistry). Enzymes were originally found while trying to ferment glucose into alcohol. Scientists couldn't figure out how to carry out this process without living yeast. Eduard Buchner proved that glucose could be turned into alcohol without living yeast by using juice he obtained from yeast, but didn't know what to call the things acting inside that juice. Enzymes translate to "in yeast"

The Effect of Temperature on the Enzymatic Activity of Amylase Enzymes are biological molecules or proteins that act as catalysts and help complex reactions occur everywhere in life. The enzyme and the substrate are in the same area, closely together. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/ substrate complex. After this, the substrate is changed. It can either be broken down or combined with another molecule to make something
