LABORATORY 3: LABORATORY 3: Basic Chemistry for Investigating Living Systems Abstract The purpose of this experiment was to explain how colorimetry can be used to qualitatively detect cellular chemical components; to chemically differentiate between proteins‚ sugars‚ starches‚ and lipids; to identify the roles of molecular components in living systems; to comprehend the value of using a systematic approach to research; and to describe why hypotheses‚ controls‚ standards‚ and quality control

usage of potato tuber cells. In experiment 5.1 in order to observe diffusion we examine the Brownian movement by observing carmine on a wet mount slide‚ and by using dialysis tubing‚ we investigate the selective permeability to reducing sugar‚ glucose‚ starch‚ and iodine potassium iodine. In experiment 5.2 we use samples of ox blood and Elodea plant to observe the net flow of water from the surrounding solution into the cells. In experiment 5.3 in order to estimate the osmolarity of the potato

reducing stomach pain‚ since the pH balance of honey can range from 3-4 it helps with the acidity. Not only stomach problems but honey can make blood sugar be in a normal range‚ studies by the U.S. national Honey Board suggests that honey lowers glucose production. Another thing honey is used for is hangovers‚ just take some crackers or bread and smother some honey on it and you’ll feel better in no time. Honey flushes the alcohol out of your system causing the hangover to go away. Honey is a perfect

Brown sugar‚ white sugar‚ raw sugar (unrefined) sugar cubes... there are so many types of sugar that you do not know what to choose. Learn the difference between refined and unrefined sugar! Experts warn that sugar contribute to some of the worst diseases: cancer‚ cardiovascular disease and diabetes. Therefore‚ you should watch out for the daily consumption of sugar and choose the least harmful alternative for your health. What is considered moderate consumption of sugar? * 8 teaspoons maximum

reactions by lowering the activation energy of the reaction without being altered during the process. The enzyme used in this experiment was the β-galactosidase purified from E. coli. This enzyme hydrolyzes lactose and turns it into galactose and glucose. Since it is difficult to assay the activity of β-galactosidase‚ we will be using the artificial substrate‚ o-nitrophenyl-β-galactoside (ONPG) instead of lactose. ONPG is an analog of lactose and an advantage of using ONPG is that it is easy to determine

make cancer grow faster. All cells‚ including cancer cells‚ depend on blood sugar (glucose) for energy. But giving more sugar to cancer cells doesn’t speed their growth. Likewise‚ depriving cancer cells of sugar doesn’t slow their growth. This misconception may be based in part on a misunderstanding of positron emission tomography (PET) scans‚ which use a small amount of radioactive tracer — typically a form of glucose. All tissues in your body absorb some of this tracer‚ but tissues that are using

Cellular metabolism encompasses the many processes that work together to keep the cells in dynamic equilibrium. Cellular metabolism is responsible for providing energy to the cell and is an essential element of life. There are several complex‚ involved processes involved in cellular metabolism including glycolysis‚ Krebs’s cycle‚ and electron transport. Metabolism itself can be broken down into two different categories: catabolic and anabolic. Catabolic metabolism involves the breakdown of large

The Effect and Rate of the Enzyme Amylase on Starch Abstract Assessing reaction speed of the enzyme amylase can be measured by the amount of glucose and maltose produced during given time intervals. I hypothesized that‚ if the reaction time is longer‚ then the amount of amylase will be larger. Enzymes are specific in their match of substrates they will breakdown – similar to a key and its lock. Since amylase is the only enzyme that breaks down starch‚ the procedure was effective and gave clear

without any fear. However‚ they intake should still be limited for people suffering from type-2 diabetes. Being alkaline in nature‚ sugarcane juice helps the body in fighting against cancer‚ especially prostate and breast cancer. Sugarcane provides glucose to the body‚ which is stored as glycogen and burned by the muscles‚ whenever they require energy. Therefore‚ it is considered to be one of the best sources of energy. If you have been exposed to heat and physical activity for too long‚ drink sugarcane
