temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient energy for the substrates to move at a fast rate‚ hence decreased the number of collisions with the enzymes. However

small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound‚ with a specific rate. The test show that mean rates of diffusion are significantly different acording to the concentration. So the concentration have an impact on the rate of diffusion. Also‚ the

It would be normal to think that immigrants and refugees will affect somehow the economy of the European nations‚ because more jobs and health coverage is required‚ but also more goods will be needed in order to meet a higher demand. Prices might increase‚ but it is important to be mindful that companies that sell inferior products might increase in revenues since refugees will be able to spend only a few euros on their goods. According to Huttl P. and Leandro A. (2015)‚ “ the net fiscal contributions

Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide. In the body

were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were functioning at a significantly reduced rate at the 24ᵒC temperature and was completely inactive at the 0ᵒC temperature. Whereas when we compare to the higher temperatures (60ᵒC) the enzymes should have functioned with reduced efficiency and should have even denatured which would

How the Amount of Water Effects Plant Growth By Dennis Marchuk Turner Ashby High School Grade 10 March 23‚ 2013 The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared

Chinese Economic Growth 1‚ Explain what is meant by Economic Growth and what this means for Chinese Productive Capacity. Economic Growth can simply be defined as the growth in the productive potential of the economy over a given period of time. It is typically measured by growth in the real GDP. Economies are constantly changing over time for a variety of reasons. Part of the change involves fluctuations in the productive capacity‚ the ability to produce goods and services. Increases in

Cash Discount on Sales Cash discount is the discount offered by seller for paying cash early. Cash discount is only offered on credit sales where the customers do not pay at the time of sale but promise to pay latter. There are two methods of accounting for sales that offer cash discounts; the gross method and the net method. These two methods are explained with the help of the following example: Example Suppose Company A sells certain goods at a price of $4‚400 with terms of payment

What is demographic transition? How can demographics of a country have an impact on its economic growth? Let me first address the first part of this question‚ Demographic transition refers to a change in the development stage of the country as it transgresses from a pre-industrialized era to an industrialized. The major change witnessed in the country will be a distinctive decrease in the birth and the death rates. This transition is illustrated through a demographic transition model
