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.
<u>Answer:
</u>
The type of factor that probably plays a bigger role in determining whether a person will try a drug in the first place, as opposed to determining which of those who try it will become dependent is the social factor.
<u>Explanation:
</u>
- The behavior that a normal person exhibits is often controlled by various factors. One of those factors is the societal pressure that the person inevitably experiences.
- The choices that are made by an individual are often influenced by the thought pertaining to the acceptance that the people show towards the choice in general.
- Hence, the social factor plays a considerable role in determining whether a person will try a drug at all or not.
The leaders of the dynasties are many, as dynasties last much longer than human life. It would mostly be the Chinese emperor of th time.
If you mean the founders: the founder of the Han was emperor Gao (previously rebel leader Liu Bang) and the founder of Qin was Duke Xiang, a leader of a war expedition.
I believe the answer would be C. (Along China's east coast due to the fertile soil found along the Yellow River and the Yangtzi River)
