the experiment was broken into three sections. The first section showed the pH and color changes that an enzyme can create. It was predicted that when potato extract‚ the enzyme‚ was added to catechol‚ the substrate‚ an enzymatic reaction would occur. The second section of the experiment demonstrated enzyme specificity. It was predicted that potato extract‚ when hydroquinone was introduced‚ would not exhibit the characteristics of an enzymatic reaction. The third section of part one focused on whether

the Irish and the impact that the potato had on their culture. The author will outline the stages of development from before the introduction of the potato to the acceptance of it as a winter vegetable. The author will also describe what effects the great famine had on Irish cuisine. The article will discuss the varieties of food‚ including the potato‚ eaten throughout the years‚ the methods of production at different levels of society‚ and a number of Irish potato dishes including boxty‚ champ‚ and

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)

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

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
