Answer: Option A. thylakoid membrane

Explanation:

Photosynthesis is the process that occurs in two sequential stages light dependent reaction ans light-independent reaction.

The H+ ion (Proton) gradient forms during photophosphorylation where cytochrome b6f and ATP synthase work together to produce ATP.

In non-cyclic photophosphorylation, the electrons produced from PS 2 pumps H+ ions from the stroma to the lumen that makes the proton gradient across the thylakoid membrane. this proton gradient is allowed to form a proton-motive force that is used by ATP synthase to produce ATP.

In cyclic photophosphorylation, the energy of electrons from PS2 and PS1 are used by cytochrome b6f uses to create ATP and to restricts the production of NADPH.

Hence, the correct option is A.

Lead is a metal found in the Earth's crust which through human practices like using it in paints and other products cause lead poisoning in humans due to accumulation of lead in the body.

Lead poisoning can affect the child above 6 years and adults and prove harmful as its increased concentration can cause severe health problems common of which are the development of anaemia due to large consumption, brain damage, reduced mental growth and severe stomach ache.
