How does water's role in photosynthesis explain
Vera_Pavlovna [14]

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.

Which theoretical perspectives would agree that the international system is inherently anarchic?
tester [92]

Realist and Liberal perspectives would agree that the international system is inherently anarchic

   The notion that there is no supreme authority or sovereign in the world is known as anarchy in the study of international relations. There is no hierarchically superior, coercive authority that can settle conflicts, uphold the law, or regulate the system of international politics in an anarchic state. It is commonly acknowledged that anarchy serves as the foundation for international relations theory.

    It is feasible for ordered ties between nations to be maintained in an anarchic international system, contrary to how anarchy is typically understood in the field of international relations. For the realist, liberal, neo- realist, and neo- liberal models of international relations, anarchy provides the underpinnings.
