affect the rate of enzymes reactions. One of them is pH‚ which influence on the enzyme activity will be the subject of this investigation. Catalase of potato tuber cells will be the enzyme used in the experiment. RESEARCH QUESTIONWhat is the influence of different values of pH on the activity of catalase in potato tuber cells?VARIABLESIndependent: potato discs treatment (placing them into buffer solutions of different pH values‚ mixed with hydrogen peroxide)Dependent: the activity of the catalase‚ reflected

Abstract The experiment was carried out to investigate at which point the potato has reached its isotonic environment. From the results‚ when the concentration increase to 0.3M‚ the mass of the potato slices decreased by -3.26%. We can conclude we see that as we increased the sucrose concentration it was a decrease in the percent change. Introduction All cells have membranes that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to

example of a soft tissue injury would be pulling or tearing your hamstring. The hamstring is located at the bag of your leg and runs from the back of your knee to just below the gluteus Maximus. This injury will occur when the muscle is overstretched and is common in most sports but especially football and sprinting due to the amount of work your legs go through. Soft tissue includes tendons‚ ligaments‚ fascia‚ skin‚ fibrous tissues‚ fat‚ and synovial membranes‚ which are connective tissue‚ and muscles

Osmosis using potato cores and sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell is

best way for people to grow economy.I mean harmony between people and nature is extreme important. If we be nice to the nature‚ so does it. So people need to not only work hard to get money but do not destroy our environment as well. If people do not change their way to be rich‚ they will pay for their mistakes Stay hungry‚ stay foolish " Stay hungry‚ stay foolish" was said by Steven Jobs in the speech for the Stanford graduated students‚ which I saw it in my TOEFL class

In a global‚ technologically driven society‚ however‚ the very idea of time has changed. Having once implied a spanning space between the hours of “nine to five” relative to the person or organization from whose vantage money was viewed‚ time is now

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The
