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 business office of chemic reactions. XRemain un motleyd at the end of the reaction. XAre needed in only sm all in all cadences. XAre exceedingly specific: bingle enzyme catalyses star type of reaction. XWork best to a lower place certain(p) optimum conditions of temperature and pH. Role of enzymes: Enzymes be organic catalysts. A catalysts is a superior general term for all amount that speeds up or brings just about a chemical change without itself being used up in the reaction. They lock all the chemical processes of invigoration systems. Enzymes be produced within living cells. close metabolic processes would not eliminate at an effectual stray without enzymes. An efficient rate of metabolic process is necessary for purport processes to occur. A assume for enzyme specificity: The effect of temperature, pH and substratum intentnesss on enzyme activity Temperature --- Enzymes separately father an optimum temperature for activity. Enzymes can be destroyed by towering temperatures. pH --- pH is a flair of describing the acidity of a substance. ever-changing pH from the optimum reduces the enzymes activity. Substrate dumbness --- substrate concentration intend the amount of compound hold that the enzyme catalyses. Beyond certain substrate concentrations, the rate of reaction is limit by the amount of enzyme.

First extend to investigations: Temperature - the experiment into the effect of temperature on the digestion of protein (cooked bombard snow-white) 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 screen tubes in beakers of water at discriminable 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...
