Detailed explanation-1: -Hydrogen ions flow down their electrochemical gradient back into the matrix through ATP synthase channels which capture their energy to convert ADP to ATP.
Detailed explanation-2: -ATP synthase uses the protons flowing into the matrix to bind ADP and Pi and release ATP.
Detailed explanation-3: -As the ions pass through, ATP synthase rotates. The rotation creates the energy needed to bind ADP and a phosphate group together to produce ATP. The electrons take on a great deal of energy, which causes them to move to a higher energy level. place in the thylakoid membranes inside of chloroplasts.
Detailed explanation-4: -These protons, or hydrogen ions, flow back across the membrane through ATP synthase. As hydrogen ions pass through the enzyme, they turn a rotary motor that induces a conformational change in ATP synthase, causing it to attach a phosphate to ADP, making ATP.
