<prompt> Kudingeka isinyathelo esengeziwe lapho kwakhiwa ama-amino acid kuphi? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Ama - chloroplast ngokwawo enza cishe wonke ama - amino acid esitshalo ngaphandle kwalawo aqukethe isulfure njenge - cysteine ne - methionine. I-cysteine yenziwa kuyi-chloroplast neproplastid kodwa futhi ihlanganiswa kuyi-cytosol nase-mitochondria, cishe ngenxa yokuthi inenkinga yokuwela ulwelwesi ukuze ifinyelele lapho idingeka khona. Ama-chloroplast ayaziwa ukuthi akhiqiza izakhi ezandulela i-methionine kodwa akucaci ukuthi i-organelle yenza ingxenye yokugcina yendlela noma uma kwenzeka ku-cytosol.
