An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

Biology Lab Report - Movement in and out of cells (4A) Shiang Chen Ting (24) Sec 313 Introduction The aim of this experiment is to explore the factors which affect the movement of materials in and out of the cells. The dark red or purple colour of Beetroots is caused by a pigment called betalain that is found within the vacuole of the beetroot cells. The pigment remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect

procedures: 1. Hydrogen G. When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused the toothpick to light up instantly for a short period and then made it glow brighter red. 3. Hydrogen and Oxygen Mixture

work properly. The focus of this study is to measure the effects of external factors of temperature‚ pH and enzyme concentration levels and how it effects the catalyst reaction times of catecholase and peroxidase enzymes using potato extract. A review on how enzymes react under certain external conditions gave a good foundation to base this experiments hypothesis when looking at concentration of enzymes‚ temperature and pH levels.

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is

Homeostatic Control of Core Body Temperature Our bodies have processes that happen to keep everything at an even rate. If things get out of balance our bodies tries to bring them back into balance. Homeostasis refers to the processes of keeping internal body environment in a steady rate‚ when the external environment is changed. The aim of this essay is to discuss the internal environment‚ the importance of regulation of core temperature‚ negative feedback and positive feedback and contrast

EFFECT OF TEMPERATURE ON CORROSION OF CERMETS ALLOY ABSTRACT Tungsten carbides (WC) are widely used as wear resistant components such as seal‚ valves‚ rings‚ nozzle and bearings. But in some processing operations‚ the environment necessarily includes severe corrosion or extremes of temperatures. In this research‚ commercially cobalt tungsten carbide (WC-6%Co) and nickel tungsten carbide (WC-9%Ni) was examined in seawater (3.5% salinity) to know the effect of temperature on corrosion for both

My topic for the science fair project is "The effect of temperature in energy loss in a basketball". Some of my subtopics for my project include the pressure air and height in a basketball‚ the material a basketball is made out of and the size of the ball. Different sports require different size balls to correspond with the correct bounce it needs to be used during the sport. Thats why you would not be able to use a tennis ball to play basketball because it is too bouncy and a soccer
