Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Most of the Hydrogen Ion “created” during the Light Dependent Reaction is primarily used to ____

A	Produce NADPH
B	Produce ATP
C	Produce Oxygen Gas
D	Produce Glucose

Explanation:

Detailed explanation-1: -The flow of hydrogen ions back across the photosynthetic membrane provides the energy needed to drive the synthesis of the energy-rich molecule adenosine triphosphate (ATP).

Detailed explanation-2: -In a process called non-cyclic photophosphorylation (the “standard” form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .

Detailed explanation-3: -Oxygen and hydrogen ions are also formed from the splitting of water. To replace the electron in the reaction center, a molecule of water is split. This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.
