Most of life’s biological processes involve the use of protein catalyst called enzymes‚ that help speed up chemical reactions within the body without being denatured in the processes. Enzymes can be used continually by temporary binding to a specific substrate in the active site to convert the substrate into a product that the cell needs to perform a specific function. Without the use of catalyst enzymes‚ homeostasis wouldn’t be able to occur quickly enough which can result in many bodily functions

Given the evidence‚ it can be determined that a reaction will occur when reactants have a kinetic energy greater than the activation energy‚ this is a theory of collision theory. For example‚ in the first experiment‚ the test tube filled with 10 mL of 3% hydrogen peroxide and had scoop of manganese dioxide‚ had a greater reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst

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

Reflections on Nutrition SCI/241 Reflecting on what I have studied so far on nutrition‚ using my assignments completed up until this point is that I have come to the knowledge of how the human body works from the moment food enters the mouth through digestion and coming out as waste. I have also obtained knowledge about how the body changes through aging‚ and how diet and exercise can actually help the body’s digestion and growth process. Two assignments I really enjoyed were week 5

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

Micronutrient and Fast Food Presentation * Recorded micronutrient intake How does your recorded micronutrient intake compare with the recommendations of the dietary reference intake (DRI)? My intake of micronutrients in the last three days does not correlate with the recommendations of the DRI. There aren’t enough vitamins in my diet and too much sodium intake. * Which foods in your recorded daily intake provide specific micronutrients (specific vitamins and minerals)? Discuss the

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

Overview of the Study The longitudinal study conducted by Stupica‚ Sherman and Cassidy (2011) examined whether there was a correlation between infant irritability (maximally vs. moderately irritable) and infant attachment (secure vs. insecure). Researchers wanted to reveal whether the two were associated when infants took part in exploration and sociability with unfamiliar adults. Stupica et al. points out many factors that may contribute to an infant’s wariness in exploration and sociability.
