The answer is the first 1. i think. :p
Polysaccharide formation allows organism to store energy efficiently. The storage form of food in animals is glycogen and in plants it is starch. Both glycogen and starch are polysaccharides of glucose. Many glucose units are linked together by condensation reaction to form polysaccharide. Compared to having several molecules of glucose in a bulk it is better to store it in the form of condensed bulk i.e polysaccharide. Thus polysaccharides which are formed by condensation reaction i.e by the loss of water molecules are easy to store.
Polysacchrides are: a) stored in the form of condensed bulk
b) they are chemically non-reactive
c) they are osmolytically inactive
Answer:
The answer to this definition is: ACTION POTENTIAL
Explanation:
Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.
Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.
