|
|
hydrogen ions are pumped across a membrane from a compartment with low concentration into one with high concentration
|
|
|
hydrogen ions flow through ATP synthase
|
|
|
a water molecule is split releasing hydrogen ions, oxygen, and electrons
|
|
|
the electron transport chain moves hydrogen ions into the thylakoid lumen
|
Detailed explanation-1: -The first process of this process is to entrap light. This step occurs as light reactions that involve photophosphorylation reactions involving photosystems I and II. The entrapped light is used in the formation of energy such as ATP and NADH.
Detailed explanation-2: -Photosystem II (PS II) is the initial phase of photosynthesis in which water molecules are broken down into hydrogen ions (H+), electrons (e-), and oxygen.
Detailed explanation-3: -This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space. Technically, each breaking of a water molecule releases a pair of electrons, and therefore can replace two donated electrons.
Detailed explanation-4: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
