Investigating the effect of temperature and

Each of these enzymes is responsible for one particular reaction that occurs in the cell. However, some of the equipment we used was not as accurate as it could have been. T- test for 0oC and 65oC 1. The first improvement I could make to my coursework if I had to repeat it is measure the mass of sodium bicarbonate being put into each experiment.

If the cells did not break down the hydrogen peroxide, they would be poisoned and die. Light intensity or distance of the Elodea from the lamp. Assembling the Respirometers Two sets of respirometers will be assembled during this lab exercise.

Check the weed to see if it is bubbling.

Investigating factors affecting the rate of photosynthesis

Place 20 non germinating seeds in the water. A data logger will be a lot more accurate way of measuring fluctuations in temperature. LED lamps produce less heat.

Find the square root of this figure. Place 20 germinating seeds in the cylinder and record the volume by reading the new level of water. Remember that the activation energy of a reaction is the minimum amount of energy needed before a reaction can take place.

This could make it inaccurate, as each measurement is accurate to the nearest mm. For it to fit exactly on the best-fit curve the average rate of oxygen should be You can improvise here, stainless steel dissection scissors, for instance, can serve to weight the tubes.

Investigation: Enzymes

Therefore rubisco will catalyse carbon dioxide and ribulose bisphosphate to GP faster as temperature increases. A digital light intensity meter should be used instead of analogue; this is so the light intensity can be measured in exact figures.

The reading shown on the above image would be. It should be soaked, but not dripping. The logger records each measurement and stores it in memory along with the time and date. Conclusion A higher magnetic field strength and a decrease in the HR resulted in an increase in body temperature during the MRI procedure.Investigate the effect of temperature on amylase activityIntroduction Amylase is an enzyme that catalyses the breakdown of starch into sugars.

Amylases are foundin almost all plants, animals and microorganisms. Investigating the effect of temperature on the rate of photosynthesis. Home / Free Essays / Before starting my investigation on how temperature affects the rate of photosynthesis I carried out some research into photosynthesis.

From this initial research I made a prediction based on the evidence that I found about the enzyme rubisco that is. Jul 04,  · To investigate the relationship between body temperature rise and the RF power deposited during routine clinical MRI procedures, and to determine the correlation between this effect and the body’s physiological response.

The Effect Temperature and Concentration Have on a Reaction Words | 8 Pages. The Effect Temperature and Concentration Have on a Reaction We must produce a piece of coursework investigating the rates of reaction, and. The Effect of Temperature. Introduction We all use low temperatures to help stop foods going off, by using fridges and freezers.

In this unit we will investigate the effect of temperature on rate of reaction and explain our observations using. Measure the effects of changes in temperature, pH, and enzyme concentration on reaction rates of an enzyme catalyzed reaction in a controlled experiment. Explain how environmental factors affect the rate of enzyme-catalyzed reactions.
