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:
Expansion lead to economic promise and fueled the manifest destiny
Explanation:
The north contained a lot of abolitionists while the south was commonly pro-slavery, this increased sectional tension because each side wanted to see their ideals extended into the west.
According to the preamble, the constitution was written because to unify the states to establish a just government to create a lasting democracy all Options are correct.
What does Preamble denotes?
A preamble is a basic and proclamation in a record that makes sense of the report's motivation and fundamental way of thinking.
The preamble makes way for the Constitution (Archives.gov). It plainly conveys the goals of the designers and the motivation behind the report. The preamble is a prologue to the most elevated tradition that must be adhered to; it isn't the law. It doesn't characterize government powers or individual freedoms.
It contains beliefs that the Constitution looks to accomplish. It provides course and motivation to the Constitution. It additionally reveres the terrific targets and financial objectives which are to be accomplished through sacred cycles.
Therefore all Options are correct.

Answer:
short-term
Explanation:
According to my research on different types of memories, I can say that based on the information provided within the question Samantha has stored the information in her short-term memory. This can be said because based on the question Samantha studied every day up to the day of the exam (short term) therefore she had the information clear in her mind for the test.
