Question

Arrange the components of photosynthetic machinery of purple bacteria in a sequence followed for flow of electrons :
A. Quinone
B. P870
C. Cyt \(bc_1\) complex
D. Cyt \(c_2\)
E. Pheophytin
Choose the correct answer from the options given below :

• A. \(C, D, A, E, B\)
• B. \(B, E, A, C, D\)
• C. \(A, D, B, C, E\)
• D. \(B, A, E, D, C\)

Hint:

Remember: \[ \text{Purple bacteria perform cyclic photophosphorylation} \] Electron flow: \[ P870 \rightarrow \text{Pheophytin} \rightarrow \text{Quinone} \rightarrow Cyt\,bc_1 \rightarrow Cyt\,c_2 \rightarrow P870 \]
• No oxygen is produced in purple bacterial photosynthesis.
