Lactase is effective at pH 2 – 7 (including dH2O) and therefore breaks down the lactose sugar in milk into glucose and galactose. As a result, the test strips will turn a shade of brown. . Lactase is not effective at pH 10 – 12. At the high pHs, the enzyme lactase is denatured and is no longer able to break down the sugar lactose in milk.
Hereditary Fructose Intolerance Enzymes are involved in processes such as the breakdown of fructose because they speed the process up. These reactions would be a lot slower without them or may not happen at all. They act as a catalyst. Fructose is used as a source of energy for our bodies. Enzymes are needed to breakdown this sugar into energy.
The reason for this I concluded, was the collision theory. At the higher molarities of Potassium Iodide there were too many moles and therefore too many collisions were happening. Therefore the product was being made almost instantly. When I reduced the concentration of the reaction this meant there were less particles of iodide in the system so the reaction was happening slower. I also lowered the concentration of Hydrogen Peroxide 0.017M.
pH > 7 is alkalinity environment that will bind hydrogen ion, and pH < 7 is acidic environment that will donate hydrogen ion. On the other hand, increasing hydrogen ion concentration will reduce the bound metal cation concentration. Decreasing hydrogen ion concentration will increase the hydroxyl ion concentration (M. Chaplin, 2004). Enzymes are one of the most efficient catalysts in biochemical reactions. They are used to speed up the reaction rates by providing an alternative reaction pathway of lower activation energy, which is the minimum energy that requires for reactions occur.
Removing VLCSFA from the diet eliminates any external contribution to the total VLCSFA blood level. Lorenzo’s Oil, made of monounsaturated fatty acids (good fatty acids), causes Competitive Inhibition to occur. The same enzyme complex that elongates fatty acid chains becomes occupied with the production of monounsaturated fatty acids. The enzyme complex cannot produce both types of fatty acids simultaneously. Therefore the two kinds of fatty acids compete for same enzyme complex; however, monounsaturated fatty acids are formed in greater concentration than VLCSFA.
Incorrect predictions: Sucrase will have highest activity at ph 6 not ph 7 Warm up exercise increases body temperature making it ideal for enzyme activity Increasing myosin activity makes muscles tougher and stiff and limits free movement for performance. Because the optimal ph level for enzyme activity in the stomach/lower intestine is ph 6 and Salivary amylase has a ph of 6.7 to 7.0 making it inactive in the
Explain. It is valid to conclude that a base were added, the rate of the reaction would slow down because the pressure of oxygen barely increased, meaning the enzymes were not working at a faster rate. 6. Predict what would happen if vinegar (also known as acetic acid) were added to a water solution of hydrogen peroxide and
Product cannot be formed any quicker as maximum efficiency as been reached and the only way to increase the rate of reaction any further would be to increase the concentration of enzymes. There are also substances that can slow down the rate of reaction, or prevent the formation of enzyme-substrate complexes altogether. The process is known as inhibition and the substances that are used are known as inhibitors. There are two main categories of inhibitors; there are competitive inhibitors and non-competitive inhibitors. Inhibition is usually reversible, when the inhibitors are removed the enzymes return to full
“Meth causes the blood vessels to constrict; it cuts off the steady flow of blood to all parts of the body. Heavy usage can weaken and destroy these vessels, causing tissues to become prone to damage and inhibiting the body's ability to repair itself.” (Visible Signs, paragraph 1) A really big appearance change that happens when using this drug is the aging process. The body loses the elasticity and luster that causes you to look young in such a short amount of time. Another really bad thing that can happen to your body with all the Methamphetamine use is the hygiene of the mouth. “The drug causes the salivary glands to dry out, which allows the mouth's acids to eat away at the tooth enamel, causing cavities.” (Meth Mouth, second
Expansion, an increase in the volume of a substance, usually due to the addition of heat to the substance. The heat causes the molecules of the substance to move farther apart, making the substance occupy more space. A loss of heat causes the opposite effect, known as contraction. Although most substances expand when heated, not all expand at the same rate. Aluminum, for example, expands twice as much as iron when both are heated the same amount.
