Question

Properties of starch useful for making it storage material are
(i) Easily translocated
(ii) Chemically non reactive
(iii) Easily digestible
(iv) Osmotically inactive
(v) Synthesized during photosynthesis
(a) (i) and (v)
(b) (ii) and (iii)
(c) (ii) and (iv)
(d) (i), (iii) and (v).

Answer 1

Hint: Starch or amylum is a polymeric sugar consisting of various glucose units joined by glycosidic bonds. This polysaccharide is delivered by most green plants as energy stockpiling. It is prepared to deliver a significant number of the sugars utilized in handled nourishments.

Complete answer:
Starch is a decent stockpiling material as a result of its few properties like
(I) It is insoluble.
(ii) It isn't effectively moved. It doesn't move away from the capacity territories.
(iii) It is osmotically latent. It has exceptionally less impact on osmotic weight. Consequently, it doesn't upset the water equilibrium of the cell.
(iv) It is effortlessly changed over back to glucose at whatever point required.
It is the most widely recognized starch in human weight control plans and is contained in enormous sums in staple nourishments like potatoes, maize (corn), rice, wheat, and cassava (manioc). Unadulterated starch is a white, dull, and scentless powder that is insoluble in virus water or liquor. It comprises two sorts of particles: the direct and helical amylose and the spread amylopectin. Contingent upon the plant, starch, by and large, 75 to $80\%$ amylopectin by weight and contains 20 to $25\%$ amylose. Glycogen, the glucose store of animals, is an all the more profoundly extended variant of amylopectin.

So the correct answer is option c)(ii) and (iv)

Note:
In industry, starch is changed over into sugars, for instance by malting, and matured to deliver ethanol in the assembling of brew, whisky, and biofuel. Blending most starches in warm water delivers glue, for example, wheat paste, which can be utilized as a thickening, hardening, or sticking specialist. The greatest mechanical non-food utilization of starch is as the cement in the papermaking cycle.
