Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on
Important Questions on Photosynthesis in Higher Plants
Assertion (A): Electrons released from the photosystem are used by the electron transport chain during photophosphorylation.
Reason (R): Movement of electrons from pheophytin to the PS-I reaction centre is an oxidation-reduction reaction.
The correct option among the following is:
Arrange the path of electrons from water to the phycocyanin in the light reaction.
i) Plastoquinone
ii) Excited
iii) Cyt
iv)
v) Pheophytin
vi) Quinone
The correct sequence is
Assertion A: During photophosphorylation protons are transported across the membrane and accumulated inside the lumen.
Reason R: To develop proton gradient, pheophytin transfers electrons to hydrogen carriers instead of electron carrier.
A) In ATPase enzyme part is embedded in the membrane and forms a transmembrane channel
B) The part of ATPase protrudes on the outer side of the membrane and a proton gradient is formed across the membrane
C) The gradient of the proton provides enough energy to cause a conformational change in particle
D) The change in particle makes the enzyme synthesize ATP
Which of the following are required for chemiosmosis?
I. A membrane
I. A neutron pump
II. An electron gradient
IV.
The correct answer is:
