OBJECTIVE: The experiment was carried out to investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different

isotonic. In Cylinder (A) the mass decreased‚ so liquid was released from the potato‚ because the cells in the potato would have burst if even more was absorbed‚ whereas the length stayed the same. In Cylinder (B) the mass and length increased‚ which means the potato cells absorbed some Sodium Chloride (NaCl)‚ so the cells don’t shrivel up and die. For Cylinder 3 the mass and length also increased‚ like cylinder (B). The potato cells would have shrivelled up if water was released‚ so by absorbing more

Potatoes The initial weights of the potato cubes ranged from 0.93-1.04 grams from the solutions containing AgNO3 (Table 1). Graph one depicts the correlation of percent change in weight for each sucrose concentration with AgNO3 added. The initial length of the potato cylinders were 2cm as depicted in table two. Graph two depicts the correlation of percent change in length in different sucrose concentrations. The initial weights for the solutions lacking AgNO3 ranged from 1.0-1.7grams (Table 3)

Osmosis is a specialised form of diffusion. Water moves from an area of LOW concentration of Solute to an area of HIGH concentration of solute through a semi-or fully permeable membrane by the process. Water moves constantly through the cell ’s membrane its estimated that about 250 times the volume of a single cell moves through 1 per second This continues until the solute concentration reaches equilibrium It is convenient to express the available energy per unit volume in terms of "osmotic

Korea. 3. Koreans LOVE 고구마 (sweet potato) and sweet potato-flavoured things. Just to give you an idea‚ here are a few varities of sweet potato snacks‚ desserts and main courses. Deep fried sweet potato‚ sweet potato cake‚ sweet potato crackers‚ sweet potato chips‚ sweet potato bread‚ sweet potato latte‚ sweet potato salad‚ sweet potato pizza. You get the idea? Don’t get me wrong‚ though‚ I’m not knocking it. I actually happen to love all of the Korean sweet potato creations… except the latte – that’s

From basic knowledge‚ the rate of reaction will affect by the concentration of the reactant. The higher concentration of reactant‚ the faster the rate of the reaction. In this experiment‚ hydrogen peroxide acts as substrate and the catalase in potato tissue is the enzyme. The equation od the reaction is: Catalase Hydrogen peroxide ----------------------------------- > oxygen + water In the set-up‚ pipette is used because it can easy to observe the movement of the

Comparative Analysis of Two Vincent van Gogh’s paintings Vincent van Gogh made “The Peasant Woman Cooking by a Fireplace” just after he completed “The Potato Eaters.” “Peasant Woman Cooking by a Fireplace” and the “Potato Peeler” both represent women working in the Nuenen period‚ spring 1885. Even though one of the paintings is a self-portrait and the other one shows a peasant women cooking‚ both paintings show working humble women engrossed in their work. Both paintings show his fascination

in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in the other assays. These variables included a boiled‚ frozen and then thawed‚ and frozen potato extract and dH2O instead of the potato extract. It was noted that the temperature and or way the potato extract was prepared effects how the enzyme with the potato will react
