1.	Which of the following amino acid is helpful in the synthesis of plastoquinone?(a) Valine(b) Isoleucine(c) Leucine(d) TyrosineI had been asked this question in exam.I need to ask this question from Chloroplast Structure and Function topic in portion Chloroplast Structure and Function of Cell Biology
Answer» The CORRECT CHOICE is (d) Tyrosine The explanation: Plastoquinone is a branched chain UNSATURATED quinone, which HELPS in the ELECTRON transport chain of photosynthesis. P-hydroxyphenylpyruvate is synthesized from tyrosine which then converts finally to plastoquinone.
