At a fundamental level, water provides electrons to replace those removed from chlorophyll in photosystem II. Also, water produces oxygen as well as reduces NADP to NADPH (required in the Calvin cycle) by liberating H+ ions
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Water also has another important role of being an electron feeder. In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH. Since NADPH is an important reducing agent present in chloroplasts, its production results in a deficit of electrons, resulting from oxidation of chlorophyll. This loss of electron must be fulfilled by electrons from some other reducing agent. Photosystem II involves the first few steps of the Z-scheme (the diagram of the electron transport chain in photosynthesis) and therefore a reducing agent that can donate electrons is required to oxidize chlorophyll, which is provided by water (acting as a source of electrons in green plants and cynobacteria). Hydrogen ions thus released create a chemical potential (chemiosmotic) across the membrane that finally results in synthesis of ATP. Photosystem II is the primary known enzyme that acts as catalyst in this oxidation of water.
Answer:
a) Renaissance
Explanation:
The Scientific Renaissance was a period of development of science (astronomy, mathematics, physics, chemistry, anatomy, etc.) that occurred during the Renaissance period (15th and 16th centuries). Thus, it represented a scientific revolution based on rationalism, which changed the way of seeing the world, that is, the mentality of people.
Thus, from the studies and discoveries of some scientists, this period allowed the advance of various fields of knowledge that would later inaugurate Modern Science. Note that the Renaissance were concerned with the study of nature, so that they valued reason rather than faith.
Although Leonardo da Vinci was one of the most important names in the Cultural and Artistic Renaissance, he was featured in the Scientific Renaissance alongside Nicolaus Copernicus, Andreas Vesalius and William Harvey.
