Explain how the light reactions would be affected if there were no concentration gradient of protons across the thylakoid membrane?

The concentration gradient of protons is potential energy and is harnessed by an enzyme called ATP synthase. ATP synthase converts the potential energy of the proton concentration gradient into chemical energy stored in ATP (the process is called chemiosmosis).
So without the protons, no ATP would be made, and therefore no light reaction would occur.

Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
What event contributes directly to the creation of a proton gradient across the thylakoid membrane?
the flow of electrons through electron transport chain II
What kind of concentration forms whenever there is a difference in concentration between one place and another?
noThe correct answer if you are dealing with cells is concentration gradient
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration

What affects osmosis?
osmosis is affected by the concentration gradient the lower the concentration gradient the faster the speed of osmosis
What will most likely happen if the hydrogen pump protein in photosystem 2 does not move H ions into the thylakoid?
Well, not enough gradient will be built up so hydrogen comes down it's concentration gradient through the synthase and synthesizes ATP. Also NADPH will be adversely affected.

Where in the chloroplast are ATP and NADPH formed during the light reactions?
The light dependent reactions take place in the thylakoid of the chloroplast. ATP is formed in the ATP synthase protein by the assistance of the hydrogen gradient produced in the electron transport chain.

Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area?
Concentration Gradient
