What is light reaction and dark reaction?
Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma.Click to see full answer.

Similarly, it is asked, what is the difference between light and dark reaction?The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.One may also ask, what is light reaction in biology? Definition. The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP and NADPH. Supplement. The light reactions take place on the thylakoid membranes of the chloroplast. Subsequently, one may also ask, where does light reaction and dark reaction occur? The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.What is dark reaction in plants?dark reaction. Any of the chemical reactions that take place during the second stage of photosynthesis and do not require light. During the dark reactions, energy released from ATP (created by the light reactions) drives the fixation of carbon from carbon dioxide in organic molecules.
