Homework Answers
Q1) All living systems must sustain a complex series of biochemical reactions in order to survive. These processes rely directly on narrow ranges of ______.
Answer:-B- Temperature.
Explanation:- All living systems has many biochemical reactions for growth and repair of damaged tissues. These reactions are called metabolism, they require high activation energy, to reduce the cell’s consumption of energy, some catalysts plays an important role. These catalysts are called enzymes, these are biological catalysts made up of protein molecules. There are several factors which affect the speed of the enzyme, these factors are concentration of enzyme, concentration of substrate, temperature, hydrogen ion concentration (pH), inhibitors etc..
Enzymes are extremely sensitive to temperature changes. Enzyme activity takes place within a narrow range of temperature. Each enzyme has a particular temperature in which it is more active that temperature is called its optimal temperature. If the temperature decreases enzyme activity lowers and when again the temperature increases enzyme can resume its activity.

is a solution that resists changes in pH when a small amount of acid or base is added to best buffer solutions are prepared from weak acids and their conjugate base added as a sodium of potassium salt. Most biological systems must maintain a very narrow range of pH; therefore, buffers allow the biological solution to function correctly. Blood is a good example of a biological system that must maintain a pH in a very narrow range from 7.3 to...

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...
