What happens to electrons when pigments in Photosystem II absorb light? They become excited and break down the pigments to relea
se ATP. They are pumped across the membrane into the thylakoid. They move through an electron transport chain to Photosystem I. They combine with oxygen and hydrogen to produce water.
When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. The high-energy electron is passed to an acceptor molecule and replaced with an electron from water.
They move through an electron transport chain to Photosystem I.
Explanation:
High-energy electrons move through the electron transport chain from photosystem II to photosystem I. Energy from the electrons is used by the molecules in the electron transport chain to transport H+ ions from the stroma into the inner thylakoid.

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
GreaterSurfaceArea
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.
Catalysts
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
