Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

Determining the equilibrium constant from pH values of changing concentrations of ethanoic acid Design Research question: How will altering the concentrations of ethanoic acid affect the pH value‚ and‚ in-turn‚ the equilibrium constant? Background information: When weak acids react‚ the reaction typically does not go to completion. Rather‚ the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium

AIM To find the acceleration of an object when falling down from a height in the presence of earth’s gravitational field‚ which is also known as free fall. Air resistance is neglected in this experiment. THEORY As an object is released from a height from the ground under the influence of the Earth’s gravitational force‚ the object will always fall under a constant rate of acceleration. Unlike in space‚ where object will just float around after being released‚ object falling on Earth will always

Background Research Yeast are eukaryotic microorganisms just like other organisms‚ they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine triphosphate (ATP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can be summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes

Original Article EDITORIAL Airlines‚ Emissions and Europe’s Sensible Plan Published: February 26‚ 2012 The carbon dioxide from airplanes accounts for about 3 percent of the world’s greenhouse gas emissions‚ a share projected to go up as air traffic rises. The European Union is now requiring airlines that fly into or out of Europe to pay a fee for these emissions. This is a smart response to an urgent problem. The United States and the other nations opposing the program should either come

Chee Yong Hui 6.5 Domino Effect IA Investigate the effect of the distance between each domino on the time taken for all the dominoes to fall Independent Variable: Distance‚ d/cm‚ between each domino. The distance d/cm is measured between the middle of one domino to the middle of the next domino Dependent Variable: Time taken for all the dominoes to be toppled to the ground. The timing will start when the 1st domino is hit by a metal ball and it will stop when the last domino falls completely
