What happens if the hydrogen pumps in photo systems i and ii and not working correctly?

If the hydrogen pumps in photosystems I and II are not working correctly, there will be a disruption in the electron transport chain of photosynthesis. This will lead to a decrease in the production of ATP and NADPH, which are necessary for the light-dependent reactions to occur. As a result, the overall process of photosynthesis will be impaired, leading to reduced plant growth and metabolism.
