Olee otú e si etinye starch n'ime mgbọrọgwụ? N'iburu ajụjụ nke mbụ n'uche, dee ihe gbara ya gburugburu bụ́ nke ga-enye azịza ya. Ọ nwere ike ịbụ 1 - 20 ahịrịokwu. Ihe ndị gbara ya gburugburu:
Ma ọ bụ, glucose monomers na chloroplast nwere ike jikọtara ọnụ iji mee ka starch, nke na-agbakọta n'ime mkpụrụ starch dị na chloroplast. N'okpuru ọnọdụ ndị dị ka CO2 dị elu nke ikuku, mkpụrụ osisi starch ndị a nwere ike ibu nnukwu, na-agbagọ grana na thylakoids. Mkpụrụ starch na-ewepụ thylakoids, ma hapụ ha n'enweghị nsogbu. Mgbọrọgwụ ndị mmiri jupụtara n'ime ha nwekwara ike ime ka stachi na-agbakọta n'ime chloroplasts, ikekwe n'ihi obere saccharose na-esi na chloroplast (ma ọ bụ karịa nke ọma, mkpụrụ ndụ osisi). Nke a na-ebelata ihe ọkụkụ na-enye free phosphate, nke na-akpali njikọ chloroplast starch. Ọ bụ ezie na ejikọtara ya na ọnụego photosynthesis dị ala, ọka starch n'onwe ha nwere ike ọ gaghị emetụta nke ọma na arụmọrụ nke photosynthesis, ọ nwere ike ịbụ mmetụta dị n'akụkụ nke ihe ọzọ na-egbochi photosynthesis.
