What splits water in the light reaction?

During Light reactions of Photosynthesis, the chlorophyll will be activated by light. This light activated chlorophyll will split the water molecule. Water molecule is split to release H+ ions and also oxygen.

What enzymes are involved in light reactions in photosynthesis?

In the Calvin cycle, ATP and NADPH are used to reduce, or fix, carbon dioxide to produce glucose. This carbon fixation reaction is catalyzed by an enzyme called RUBISCO, a highly abundant protein in plants and possibly the most abundant protein on Earth.

What is the enzyme in photosynthesis?

The enzyme Rubisco, short for ribulose-1,5-bisphosphate carboxylase/oxygenase, is the enzyme that incorporates CO2 into plants during photosynthesis. As it constitutes about 30\% of the total protein in a plant leaf, Rubisco is probably the most abundant protein on earth and a major sink for plant nitrogen.

What is the name of this process that splits water?

Splitting water into its two components is much easier to do and is called water electrolysis. Making hydrogen or oxygen this way seems simple. But as you probably suspected, this reverse reaction needs an energy input, which is why it is also called an endothermic reaction.

What is another name for the light independent reactions?

The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.

Is NADPH an enzyme?

This category groups enzymes that use nicotinamide adenine dinucleotide (NADP+ and its reduced form, NADPH) in redox reactions. In general, the NADP is not stably associated with the enzyme, being a coenzyme; hence, we call such enzymes “NADPH-dependent” enzymes, rather than simply “NADPH enzymes”.

Where does water split in photosynthesis?

photosystem II
A water splitting catalyst Light-induced catalytic water splitting takes place at a metal complex which is embedded in a large membrane protein (photosystem II). This complex is composed of four manganese atoms (Mn) and one calcium atom (Ca), which are held together through a network of oxygen bridges (see image).

What is solar water splitting?

Solar water splitting directly converts solar energy into H2 fuel that is suitable for storage and transport. To achieve a high solar-to-hydrogen (STH) conversion efficiency, elaborate strategies yielding a high photocurrent in a tandem configuration along with sufficient photovoltage should be developed.
