Under anaerobic conditions, yeast carries out glycolysis to produce ATP, followed by alcoholic fermentation which produces and .

Carbondioxide and ethanol

Explanation:

After completion glycolysis under anaerobic conditions in the yeast which takes place in the cytosol, depending on the circumstances of the cell such as the yeast which is unable to carry out aerobic respiration will progress unto the anaerobic stage which is called alcoholic fermentation. This condition allows for the conversion of pyruvate formed from glycolysis to carbondioxide and ethanol that occurs with the help of two enzymes: pyruvate decarboxylase and alcohol dehydrogenase respectively.

From pyruvate to acetaldehyde

(Pyruvate decarboxylase; CO2 removal)

From acetaldehyde to ethanol

(Alcohol dehydrogenase)

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.
