Why does PS II require electrons from water?

A monochromatic light source of power 5mW emits 8 xx 10^(15) photons per second. This light ejects photo electrons from a metal surface. The stopping potential for this set up is 2V. Calculate the work function of the metal.

(I) Cadmium show photoelectric emission for ultraviolet light. (II) Photosensitive materials eject photo electrons (III) The photocurrent becomes zero at a particular negative potential (IV) The liberation of electrons fromany surface of a substance is electron emission

Assertion : The metabolic pathway through which the electron passes from one carrier to another is called the electron transport system (ETS) Reason : ETS is present in the inner mitochondrial membrane.

Assertion (A): The first form of life could have come from pre-exiting non-living inorganic molecule. Reason (R) :This the basis of chemical evolution of life.
