Effect of Catalase at Different Temperatures Abstract The role of this experiment is to determine the effect of temperature on enzymatic activity. The results of the experiment were the colder the temperature the slower the reaction rate and the hotter the temperature the faster the reaction rate. Introduction Enzymes are chemical substances found in living cells and they act as catalysts of the various chemical reactions that occur in them.(Preszler‚ 2012) They bind to substrates that have

Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers

RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

particles either consist of particles that are either hot or cold. High temperature bodies‚ are often caused due to the high heat transfer‚ which is created by chemical reactions‚ nuclear reactions‚ electromagnetic dissipation‚ or mechanical dissipation. Heat is generally transferred between two different objects by radiation‚ conduction and convection. Heat is only passed on between objects‚ with the help of different temperatures.

“There is growing acceptance all over the world that the quality of the teacher is the most important determinant of how much students learn. In this context‚ it makes sense to check that the national curriculum provides the right balance between providing a firm structure for shared national expectations for what students should learn and allowing enough scope for teachers to have the freedom to use their creativity to maximise student learning.” Discuss. The aims of the national curriculum are

In "The Woodspurge" Dante Gabriel Rossetti uses plain and forceful language to recreate a moment of contemplation and grief. He narrates a basic scene from the perspective of an unknown person in which the individual wanders in a natural setting‚ sits down‚ and‚ in an emotional state‚ observes the details of a particular woodspurge — a European herb with greenish yellow flowers. The first stanza focuses on the wind and the narrator’s movement‚ which mimics the wind patterns. As Rossetti writes‚
