Water is prevented from entering the active site of glycogen phosphorylase. What are the advantages of excluding water from the active site? to prevent the unnecessary breakdown of glycogen to maintain energy supplies in muscle cells to prevent the formation of glucose to prevent energy waste by conserving the ATP ATP that would be needed to phosphorylate glucose to prevent hydrolytic cleavage of glucose 1‑phosphate

to prevent the formation of glucose,

to maintain energy supplies in muscle cells

to prevent energy waste by conserving the ATP ATP that would be needed to phosphorylate glucose

Explanation:

Glycogenlysis,the  breakdown  of glycogen involves the activities of glycogen phosphorylase. This enzyme phosphorylated glycogen to glucose-1-phosphate. The latter in  presence of  enzyme phosphoglucomutase is  converted to Glucose-6-phosphate. (GP6)

GP6  enters glycolysis straight, to produce pyruvate.This  step   has shunted ATPs   consumption  of the usual  glucose phosphoryaltion   of  the glycolytic pathway , thus  conserving more energy for the muscles cells.

However if the glycogen phosphate active site was exposed to water, it will  be hydrolyzed to glucose,( instead of glucose-1-phosphate).The glucose  will   pass through the normal ATPs consuming  glycolytic pathways, losing more energy.

Therefore to prevent glucose formation,  to conserve energy  for  immediate availability to  ever demanding muscles cells, water is excluded from the active site of glycogen phosphorylase.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
