In photo system-I, the first electron acceptor is

Chemiosmosis requires

I. a membrane

II. a proton pump

III. a proton gradient

Select the correct option

What is the function performed by plant pigments?

Read the following and choose the option containing correct pair

I. DCMU Herbicide Inhibitor of non-cyclic electron transport

II. PMA Fungicide Reduce transpiration

III. Colchicine Alkaloid Causes male sterility

IV. Soilrite Sodium alginate Encapsulation of somatic embryos

I. The electrons that carriers photophosphorylation are located in the thylakoid membrane

II. During photophosphorylation, the chloroplast stroma becomes more acidic than the interior of thylakoid membrane

III. Protons diffuses through the protein channels which are ATP synthetase molecules

IV. ATP is formed from ADP + Pi on the stroma side of the thylakoid in the chloroplast

V. During photophosphorylation, water ionises to form ${H^ + }$, yielding electrons to PS-II
