Task: Answer Verification
Input (English): Question: Is transsulfuration an active pathway for cysteine biosynthesis in Trypanosoma rangeli?
Answer: These findings demonstrate that the RTS pathway is active in T. rangeli, suggesting that this may be the only pathway for cysteine biosynthesis in this parasite. In this sense, the RTS pathway appears to have an important functional role during the insect stage of the life cycle of this protozoan parasite.
Output (English): yes
