The first talks about keeping an active lifestyle‚ like exercising‚ to extend life expectancy. Meanwhile‚ the other article talks about good nutrition being the best anti-aging solution. You may think that the answers from the articles were unsatisfactory or unadventurous; however‚ it is the hardest path to follow and the hardest to persevere. Are you willing to take the challenge?

Hypothesis: I hypothesis that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of substrate. Enzymes are protein molecule that acts as biological catalyst by increasing the rate of reactions without changing the overall process. They are long chain amino acids bound together by peptide bonds. Enzymes are seen in all living cells and controlling the metabolic processes in which they converted nutrients into energy and new

1 WHAT IS NUTRITION? Latin derivative‚ nutritio‚ nourish • “All the processes involved in the taking in and utilization of food substances by which growth‚ repair‚ and maintenance of activities in the body as a whole or in any of its parts are accomplished. Includes ingestion‚ digestion‚ absorption‚ and metabolism (assimilation). Some nutrients are capable of being stored by the body in various forms and drawn upon when the food intake is not sufficient.” Tabers

Factors that Affect the Rate of Reaction of Peroxidase Purpose: To determine the effect of various factors on the rate of reaction between an enzyme and its substrate‚ and also to determine the optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the

The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions they were placed into a spectrophotometer (A580) for analysis. Graphing the values of the absorbance to time for each pH it was found that the rate of reactions in the neutral pH solutions were

ribosomes in a cell. They act as catalysts during biological reactions; therefore‚ enzymes are able to speed up these reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed reaction is reduced or can be stopped if the temperature becomes

time now. I’ve always been interested in nutrition and all the different things about it. I’ve always wanted to know all the different foods that you can eat to help you stay healthy and in shape. Also‚ nutrition has just always caught my attention and they were always the classes that I excelled in. My parents never really let me eat fast food and I never understood why until I was older. They would always refer to it as “junk” and tell my sisters and I how it would make us overweight and ruin our
