What membrane activities require energy from ATP hydrolysis?
Sodium ions moving out of the cell
Where does the energy come from to make ATP at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
Is it true that temperature is the measure of average kinetic energy of a substance?
Almost. Temperature is a measure of the average kinetic energy of the particles which constitute the substance. So the temperature of a block of Sodium Chloride is a measure of the average kinetic energy of the sodium and the chlorine ions which constitute the block, but temperature has nothing to do with the kinetic energy of the whole block, which may be dashing through the air at some enormous velocity.
Where do the photons that are absorbed go when they are absorbed by the solution?
Photons absorbed by a solution "disappear" and the energy they brought with them is transferred into the solution. That energy appears in the "activity" of the atoms, molecules and/or ions in the solution. The kinetic energy of these particles will increase because of the added energy.
The energy from the electrons moving down the chain is used to move H ions across the?
Energy from the electrons move down the chain is used to move H plus ions across the inner membrane. H plus ions move through channels of ATP synthase in the inner membrane.

Heat cause kinetic energy within an element or compound.

A measure that is proportional to the average kinetic energy of atoms molecules or ions present?
Thermometer
What influences the movement of ions and molecules across cell membranes?
A membrane potential is basically the difference between the inside and outside of the cell. Ions are charged, and so will change the membrane potential (the difference between charges on the inside and outside) when they move. Please see the related link below which includes a diagram of how ions affect membrane potential.
Why is a potassium sodium pump needed?
The process of moving sodium and potassium ions across the cell is an active transport process involving the hydrolysis of ATP to provide the necessary energy.
