Chemiosmosis in Photosynthesis

Photophosphorylation

1) H+ (protons) are pumped through the mebmbrane from ______________ to ______________

2) H+ ions (protons) flow through ATP synthase from ___________ to ________

Homework Answers

Answer #1

1.Ans-mitochondrial matrix, inter membrane space.

The energy of electrons is used to pump H+ (protons) from the matrix into the intermembrane space to store the energy in the form of a transmembrane electrochemical gradient.

2.Ans- inner mitochondrial membrane, mitochondrial matrix

The H+ ions move from inner mitochondrial membrane into mitochondrial matrix through ATP synthase and release energy which is used to combine ADP+ P to form ATP
