Q. The formation of which of the following in the chloroplast is affected by a deficiency in nitrogen?

(a) Glyceraldehyde 3-phosphate (b) Starch (c) Enzymes (d) Carbohydrates

My thoughts:

Nitrogen is used in both of chlorophyll and in converting carbohydrates into proteins so I am puzzled between glyceraldehyde 3-phosphate and enzymes.

However, glyceraldehyde 3-phosphate, starch and carbohydrates are nearly identical in this context and enzymes aren’t produced in the chloroplast either.

    $\begingroup$ This question was asked in a national Biology exam in my country and the majority are split between PGAL (nitrogen is used in chloroplast) and Enzymes (nitrogen is used to convert carbohydrates to proteins) so I wanted to hear other opinions. I’m still new here so I don’t know how this opposes the point of this page? $\endgroup$

    $\begingroup$ No idea. I don’t know what PGAL is. Does it contain N? Also, your title is sure to collect down votes. Change it to something like “Nitrogen deficiency and chloroplast function”. $\endgroup$
