Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency

Determining the Rate of Osmosis through a Semi-Permeable Membrane Schneider‚ Justin* Sec 16 and Thomas Hudson Introduction Water is the principle solvent in cells. There are three conditions that a cell may be subjected to in the cells physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water through their roots‚ and is also used in kidney dialysis

PH farmers’ Coco levy funds: A brief history Coconut levy is the tax collected from the exacted exported coconut and coconut products under the Republic Act 6260 or the “Coconut Investment Act”. In 1972‚ the first of these levies was implemented and known as the “Cocofund Levy”. The tax exacted from these levies was 5.50 pesos per metric ton which was equal to 55 centavos per 100 kilos of copra that was produced for that year onwards until they reached the accumulation point of P100 million.

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

This study was conducted to determine the effects of plant extracts from garlic allium sativum‚ Oregano Origanum vulgare‚ and guava Psidium guajave) as vase solution. Extract used for the preparation of vase solutions were taken from fresh garlic cloves‚ oregano and guava leaves. Water extracts were subjected to water bath at 50’C-60’C for 5 minutes for pasteurization. Flower buds were placed in plastic cups containing vase solutions with varying concentrations of extracts. Observation was done for
