What Are The Products Of The Light Dependent Reactions

These reactions occur in the stroma the fluid filled area of a chloroplast outside the thylakoid membranes.

What are the products of the light dependent reactions. The carbohydrate molecules made will have a backbone of carbon atoms. These reactions take the products atp and nadph of light dependent reactions and perform further chemical processes on them. The products of the light dependent reactions atp and nadph have lifespans in the range of millionths of seconds whereas the products of the light independent reactions carbohydrates and other forms of reduced carbon can survive for hundreds of millions of years. Both together are the source of the biochemical energy that other plants and animals use to survive.

There are four major protein complexes in. 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. The process known as the calvin cycle uses products of the light dependent reactions atp and nadph and various enzymes therefore the light independent reaction cannot happen without the light dependent reaction. Atp nadph and oxygen gas.

The actual fixation of carbon dioxide which diffuses into the leaf from the atmosphere occurs by a cyclic series of reactions called the calvin cycle named after one of the pioneer researchers in this area a summary of the calvin cycle is illustrated in. Light independent reactions take place in plant chloroplasts in this process sugars are made from carbon dioxide. The calvin cycle uses the reducing powers atp and nadph from the light dependent reactions to produce sugars. The products of light dependent reactions of photosynthesis are a.

The light independent reactions can proceed once products nadph and atp of the light dependent reactions are present in the chloroplast.
