Light dependent reaction. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. There are four major protein complexes in. Light dependent reaction is a photochemical reaction taking place in all green coloured plants within the thylakoid membranes of the chloroplast. For atp it is a phosphate atom and for nadph it is a hydrogen atom.

The light dependent reactions harvest light energy and use that energy to transport electrons through an electron transport chain embedded in the thylakoid membrane. In photosynthesis the light dependent reactions take place on the thylakoid membranes the inside of the thylakoid membrane is called the lumen and outside the thylakoid membrane is the stroma where the light independent reactions take place the thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions. In the light dependent reactions energy absorbed by sunlight is stored by two types of energy carrier molecules. This is the currently selected item.

Light dependent reactions analogy. Chlorophyll is the primary photosynthetic pigment. The reactions create atp and napdh from precursor chemicals and water using energy captured from light by dyes such as chlorophyll. The light dependent reactions synthesise atp and the reductant nadph.

Photosystem ii electrons are energised by light electrons replaced by photolysis of water molecules. The energy changes oxidation reduction that occur during photosynthesis may be represented as a z scheme. Conceptual overview of light dependent reactions.
