Question

Put the following events of the light-dependent reactions in the order in which they occur:

photosystem I, photosystem II, making NADPH, and pumping hydrogen ions into the inside of the thylakoid.

Answer 1

photosystem 2, photosystem 1, pumping hydrogen..., and making NADPH

Answer 2

Conversion of the light energy into the chemical energy for the cell to use is called light-dependent reactions.

The correct order of the events of the light-dependent reactions are:

• Photosystem II

• Photosystem I

• Pumping hydrogen ions inside the thylakoids

• Making NADPH

This order of the event can be explained as:

• The plant in the presence of light uses the sun's energy to split water molecules into ATP and NADH.

• Light energy first gets confined in Photosystem II and then gets relinquished over different photo pigments.

• After the energy is absorbed the electron gets transported to PS I. New electrons are combined and the energy level is very high.

• Large energy electrons get transported to the ETC and the electron along with NADP⁺ generates NADPH.

Therefore, the correct order is: Photosystem II ⇒ Photosystem I  ⇒ Pumping hydrogen ions inside the thylakoids  ⇒ Making NADPH.
