Enzyme Catalysis Abstract: Catalysis is an enzyme that decomposes hydrogen peroxide into oxygen and water. In this lab we will conduct a series of experiments to determine the affects of; pH‚ temperature‚ and concentration change on such catalysis. After completing the experiments we determined that catalase works most efficiently when in a 27°c‚ 50% (5 ml of catalase – 5ml of water)‚ and a normal body pH of 7°.

TITLE: EFFECT OF DEEP FAT FRYING ON OIL QUALITY AND SENSORY ATTRIBUTES OF POTATO CHIPS/ CHICKEN NUGGETS ABSTRACT: RBD Palm olein oil is a type of vegetable oils with the ratio of saturation to unsaturation 40%: 60%. Soybean oil is another type of vegetable oils with the ratio of saturation to unsaturation 20%: 80%. In addition to the chemical alterations that occur during frying‚ changes in the oil’s physical and thermal properties‚ such as surface tension‚ viscosity‚ density‚ specific

Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity:

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein

“chicken analogy.” A chicken has two different types of meat‚ white and dark. The white meat is from the breast and the dark meat is from the legs. The only time a chicken uses its breast‚ or pectoral‚ muscles is in flight‚ and it never flies far. It is only used when the fox enters the hen house and the chicken has to get out of there quickly. This is the fast-twitch muscle fiber. The slow-twitch endurance type of muscle is in the legs‚ because a chicken spends all its time walking. What makes

| [pic] Introduction Enzymes are catalysts which speed up a reaction by providing an alternative reaction pathway of lower activation energy. But they do not undergo permanent changes and so they remain unchanged even at the end of the reaction. Many enzymes consist of proteins and non-proteins called the cofactor. The intra- and intermolecular bonds that hold proteins in their secondary
