Question

respond to the following based on your reading. question 1 explain the basic steps in the first half of photosynthesis (light - dependent reactions). describe the use of light, the use of water, and what happens to the electrons.

Explanation:

Light - dependent reactions start when light is absorbed by chlorophyll in photosystems. This excites electrons. Water is split, releasing oxygen as a by - product and providing electrons to replace the excited ones. The excited electrons are passed through an electron transport chain, generating ATP through chemiosmosis and reducing power in the form of NADPH.

Answer:

Light is absorbed by chlorophyll in photosystems, exciting electrons. Water is split, releasing oxygen and providing replacement electrons. Excited electrons are passed through an electron transport chain to generate ATP and NADPH.
