INTRODUCTION Enzyme is a biological catalyst that acts on a molecule called substrate and it also significantly speed up a chemical reaction by lowering the activation energy. In order to learn about the enzyme and its behaviour‚ this lab practical is conducted to examine the kinetic of the enzyme alkaline phosphatase. As illustration‚ when alkaline phosphatase is added to a substrate called p-Nitrophenyl phosphate (colourless in alkaline solution)‚ a series of reaction takes place and eventually

Measure the potassium iodide. Weigh out approximately 2 g of solid KI. This amount is a large excess over that which is needed. 3. Oxidize the iodide ion with hypochlorite ion. Using a graduated cylinder‚ transfer 25 mL of the dilute bleach into an Erlenmeyer flask. Add the KI and about 25 mL of distilled water. Swirl to dissolve the KI. Working in a fume hood and slowly with swirling‚ add approximately 2 mL of 3 M HCl. The solution should be a dark

Ashwarya Subhluxmi The Status of women in India The lifestyle of Indian women has undergone colossal changes each millennium. In the Vedic period‚ roughly between 1700 and 1100 BCE‚ when the first Hindi scriptures also known as Vedas in Sanskrit were being composed‚ women enjoyed a very privileged life. Most of them were educated and considered to be intellectually competent with their male counterparts. However‚ in the medieval period lasting from 8th to 18th Century‚ their life became really

equals the change in kinetic energy of the object: Wnet = Kf - Ki This relationship is called the work energy theorem W = Fdcosø When the energy of the body increases‚ work is positive. Examples: 1. A boy pushes a 5.00 kg cart in a circle‚ starting at 0.500 m/s and accelerating to 3.00 m/s. How much work was done on the cart? Answer: W= Kf- Ki = (0.5)m(vfinal)2 - (0.5)m(vinitial)2 W = (0.5)(5.00)(3.00)2 - (0.5)(5.00)(0.500)2 W =
