Identify and find the incorrectly labelled structures with their characteristics.
Options
- A(a)-P680 (PSII):The primary acceptor of electron which is located towards the outer side of the membrane.
- B(c)-Cytochrome B6f: Electron carrier on the inner side of the membrane, the proton is released into stroma as
- C(d)-P700(PS I):Along with electrons that come from the acceptor of electrons of PS I, protons are necessary fo
- D(b)-Plastoquinone:It is not an electron carrier but an H carrier. Hence, this molecule removes a proton from t
Correct answer
B. (c)-Cytochrome B6f: Electron carrier on the inner side of the membrane, the proton is released into stroma as
Step-by-step solution
(b) As electrons move through the photosystems, protons are transported across the membrane. This happens because the primary accepter of electron which is located towards the outer side of the membrane transfers its electron not to an electron carrier but to an H carrier. Hence, this molecule removes a proton from the stroma while transporting an electron. When this molecule passes on its electron to the electron carrier on the inner side of the membrane, the proton is released into the inner side or the lumen sid
