Question

what is function of leucoplast​

Answer 1

Answer:

Leucoplasts are a group of plastids that include many differentiated colorless organelles with very different functions (e.g., the amyloplasts), which act as a store for starch in non-green tissues such as roots, tubers, or seeds

Answer 2

Answer:

The oxidative pentose phosphate pathway in leucoplasts provides reducing equivalents for nitrite reduction

In leucoplasts the reducing equivalents required for the reduction of nitrite and the formation of glutamate are provided by oxidation of glucose 6-phosphate via the oxidative pentose phosphate pathway (section 6.5, Fig. 10.8). The uptake of glucose 6-phosphate proceeds in counter-exchange for triose phosphate. The glucose 6-phosphate-phosphate translocator of leucoplasts differs from the triose phosphate-phosphate translocator of chloroplasts in transporting glucose 6-phosphate in addition to phosphate, triose phosphate, and 3-phosphoglycerate. In the oxidative pentose phosphate pathway, three molecules of glucose 6-phosphate are converted to three molecules of ribulose 5-phosphate with the release of three molecules of CO2, yielding six molecules of NADPH.
