investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can

The cell‚ which is the smallest unit of life‚ is surrounded by a plasma membrane. The plasma membrane functions somewhat like a wall‚ as it keeps the internal contents from the external environment. Just like a wall‚ the membrane is also somewhat permeable‚ except that the membrane takes a much more active role in determining what is allowed in to the cell and what is kept out. The plasma membrane is a very thin structure‚ which has some very important tasks. One of the main tasks that it performs

project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the speed at which

Effects on Survivors of Concentration Camps Many people during the 1940s were put into concentration camps‚ and after getting out‚ if they did get out‚ suffered many problems. The stress and torment these people went through was pure murder (Nelken). The humans put into these concentration camps were from many different races‚ and also included the mentally retarded‚ severely handicapped‚ insane‚ and very sick people (Austin). Survivors of concentration camps faced psychological‚ spiritual‚ physical

trying to find out what the concentration of the solutions is inside the vacuole of a potato cell. We will investigate how the mass of the potato chips change in different sucrose solution concentrations. We will use osmosis to do this. I will be measuring and controlling many different variables‚ these include; - The dependent Variable Weight of potato chip Independent Variable Concentration of sucrose Control Variables consist of; - 1. Temperature 2. Surface area of potato

1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface‚ and two fatty acid tails hanging from it. The membrane is double‚ so at the tip of the fatty acid tails‚ there are two more fatty acid tails attached to another phosphate head. This is what it looks like: <br> <br>The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to

test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze a
