Chloroplasts, Pigments And Photosystems in Photosynthesis
This is a description of the interactions between chloroplasts, pigments and photosystems; AKA the light dependent reactions of photosynthesis.
Plants use organelles called chloroplasts to harvest light energy to perform photosynthesis. This light energy is used to power the portion of photosynthesis called the Light Dependent Reactions. During the Light Dependent Reactions, water, photons of light come from the sun and activate 3 processes; the making of ATP, the making of NADPH and the photolysis of water. The components of the broken up water molecule, H+, H+, O and some electrons, are each used. The oxygen is released into the atmosphere as an oxygen molecule, and the hydrogens are tapped to create a gradient to drive the processes of creating ATP. The electrons are used to spur the creation of NADPH. The ATP and NADPH then go on to power the Light Independent Reactions, aka the Calvin Cycle.
