What Are The Products Of The Light Reactions

The light reactions absorb light and harness the energy to power electron transfers.

Photosynthesis occurs in two steps. Start studying reactants and products of light dependent and independent reactions. Cellular respiration is complementary to photosynthesis and uses the products of photosynthesis. Most photosynthetic organisms capture visible light although there are some that use infrared light.

Here carbon dioxide and water are converted in the presence of sunlight to glucose and oxygen. The energy of the absorbed light transfers hydrogen ions and electrons to nadp changing it to nicotinamide adenine dinucleotide phosphate nadph. The thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions. Photosystem ii psii cytochrome b6f complex photosystem i psi and atp synthase.

Co2 water chlorophyll and sunlight are four important requirements for this process. The light reactions also known as photolysis reactions convert energy from the sun into chemical energy in the form of nadph and atp. 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 the carbohydrate molecules made will have a backbone of carbon atoms.

The reactants in the light dependent chemical reaction are adenosine diphosphate adp oxydized nicotinamide adenine dinucleotide phosphate nadp and the hydrogen in water. Dark reaction it is a light independent reaction. There are four major protein complexes in the thylakoid membrane. These four complexes work together to ultimately create the products atp and nadph.
