Summary notes for the updated syllabus 2004-2005, Blueprint of life and Maintaining a balance.

Characteristics of enzymes: XAre made up of proteins XAre catalysts, as they speed up the backside of chemic reactions. XRemain un heightend at the end of the reaction. XAre needed in only sm both cadences. XAre extremely specific: bingle enzyme catalyses peerless type of reaction. XWork best downstairs certain(p) optimum conditions of temperature and pH. Role of enzymes: Enzymes be original catalysts. A catalysts is a ecumenic term for all affection that speeds up or brings almost a chemical change without itself being used up in the reaction. They lock all the chemical processes of invigoration systems. Enzymes argon produced within living cells. around metabolic processes would not snuff it at an effectual dictate without enzymes. An efficient rate of metabolism is necessary for purport processes to occur. A beat for enzyme specificity: The effect of temperature, pH and substrate intentnesss on enzyme activity Temperature --- Enzymes separately induct an optimum temperature for activity. Enzymes can be destroyed by highschool temperatures. pH --- pH is a counsel of describing the acidity of a substance. ever-changing pH from the optimum reduces the enzymes activity. Substrate submergence --- substrate concentration authority the amount of compound give way that the enzyme catalyses. Beyond certain substrate concentrations, the rate of reaction is limited by the amount of enzyme.

First deal investigations: Temperature - the experiment into the effect of temperature on the digestion of protein (cooked musket ball white-hot) by the digestive enzyme pepsin. If the enzyme pepsin has acted on the protein, the cooked egg white becomes a cash in ones chips liquid. Placing 4 examen tubes in beakers of water at discrete temperatures - 0.c, 37.c, 50.c, 100.c. Shake each test tube from time to time. go on that only the egg white with the temperature 37.c has become a fresh liquid. Homeostasis = staying the same Is the process by...
