Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones

The Effect of Starch on the Activity of Amylase with pH Variable Lab Report‚ Fall 2011 East Tennessee State University Department of Biological Sciences By: Shelby Brackett Date Performed: October 10‚ 2011 Lab Instructor: Joseph Kusi Biology 1111‚ Section 018 Abstract Enzymes are very important in chemical reactions. They are used to speed up the reaction taking place. They act by binding to a specific substrate and form an enzyme-substrate complex that may put stress on chemical bonds

Junk Food Sucks Eating junk food can have a significant impact on one’s health. Though many people enjoy eating junk food and think it tastes great. The term "junk food" typically refers to foods that are relatively high in caloric content‚ but low in nutritional value. Junk food is often high in sugar‚ salt‚ white flour‚ and fat. A few examples of foods often considered to be junk food include fast food‚ sweets such as ice cream‚ candy‚ donuts‚ and prepackaged treats

MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main

A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0

unk food is a derisive slang term for food that is of little nutritional value and often high in fat‚sugar‚ salt‚ and calories.[1][2][3] It is widely believed that the term was coined by Michael Jacobson‚ director of the Center for Science in the Public Interest‚ in 1972.[4] Junk foods typically contain high levels of calories from sugar or fat with little protein‚ vitamins orminerals. Foods commonly considered junk foods include salted snack foods‚ gum‚ candy‚ sweet desserts‚ fried fast food‚ and

Eating junk food can have a significant impact on one’s health. Though many people enjoy eating junk food and think it tastes great‚ the health consequences can be serious‚ and can range from everything to low energy levels to weight gain and illness. The term "junk food" encompasses a fairly broad category of food‚ but it typically refers to foods that are relatively high in caloric content‚ but low in nutritional value. Junk food is often high in sugar‚ salt‚ white flour‚ and fat‚ particularly saturated
