The control of which enzyme exerts the most control on glycolysis?
hexokinase
phosphofructokinase
glucose-6-phosphatase
aldolase

phosphofructokinase

Explanation:

Phosphofructokinase 1, also known as PFK-1, is the second glycolysis regulatory enzyme and its main regulatory point. Therefore we can state that this enzyme is exerts the greatest control over glycolysis.

Phosphofrutokinase is an allosteric enzyme belonging to the phosphotransferase family that catalyzes a phosphorylation: the conversion of fructose-6-phosphate and ATP into fructose-1,6-bisphosphate and ADP, a key step in regulating and limiting glycolysis rate in response to the cell's energy needs through the allosteric inhibition process

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.
