photosynthesis is the fixation of carbon dioxide and it's subsequent reduction to carbohydrate using hydrogen from water.
two sets of reactions are involved, light-dependent and light-independent
light-dependent reactions:
these include synthesis of ATP in phosphorylation and the splitting of water by photolusis to give hydrogen ions. these ions combine with NADP (hydrogen carrier) to form reduced NADP. ATP and reduced NADP are passed from light-dependent to ligt-independent reactions. this process could be cyclic (involves photosystem I only) or non-cyclic which involves both photo systems.
light-independent reactions:
carbon dioxide fixation occurs when it combines with a 5 carbon sugar called ribulose bisphosphate (RuBP) two give 2 molecules og a 3 carbon compound, glycerate 3-phosphate. this compound then turns into triose phosphate sugar in the presence of ATP and reduced NADP.
these triose sugars are then used to form hexose sugars or are converted to acetylcoenzyme to be used in the synthesis of amino acids and lipids. some triose sugar is used to regenerate RuBP. the lght-independant process is called calvin's cycle.
The conversion of light energy into chemical energy stored in organic compounds
The light dependent reaction happens when solar energy is captured to make a molecule called ATP (adenosine triphosphate)
The conversion of CO2 and H2O into sugar using sunlight as the energy source.
Photosystem I and II are two types of reaction centers found in thylakoid membranes, which are the sites of protein synthesis located in the leaves of plants. The function of reaction centers is to convert light energy into chemical energy (photophosphorylation). Now the difference between photosystem I and photosystem II is that each is able to absorb a particular wavelength. Photosystem 2 has a maximum absorption at a wavelength of 680 nanometers. Photosystem 1 best absorbs light at a wavelength of 700 nanometers. Hope this helps!

Oxygen-18 is a natural, stable isotope of oxygen. It is found in the atmosphere and can be found in ice cores to track the temperature over thousands of years as it causes the temperature of the Earth to rise with the higher ratio of 18O compared to 16O. Oxygen 18 was used to give an in sight into photosynthesis as it allows the amount of oxygen taken up during photosynthesis to be measured and showed where the oxygen came from and where it ended up. Scientists firstly added oxygen- 18 to the carbon dioxide and no oxygen- 18 was released, however, when they added oxygen- 18 to the water oxygen- 18 was recorded leaving the plant which shows the oxygen originates from the water. Scientists also discovered that some of the oxygen produced during photosynthesis didn't leave the plant but the majority left the plant through the stomata which is what allowed respiring animals such as Humans to evolve. Carbon- 14 is a radioactive isotope of carbon, naturally found in the stratosphere and troposphere and is used is radiocarbon dating to date an archaeological, geological and hydrogeological samples. It was used to know what the first products of photosynthesis are and to track the carbon during photosynthesis as it is easy to track in the plant because it is different to the other carbon involved. The experiment began by briefly exposing a green plant to 14CO2 along with light. Straight after this exposure the plant is immersed in boiling water which ceases all biochemical reactions. All the chemical compounds were then extracted and studied to see if they contained carbon- 14. With the brief exposure to carbon- 14 the only compound that contained it was phosphoglyceric acid, a 3 carbon molecule. Scientists have the green plant longer exposure to the isotope and discovered that a variety of compounds contained it, including glucose. With varying lengths of exposure scientists were able to track the sequence from phosphoglyceric acid to glucose. The insight into photosynthesis this gave us was that it showed where the carbon went during photosynthesis and what products were made at the end of this reaction. This investigation was first done by Melvin Calvin and his colleagues.

I would summarize myself and my objectives by giving a brief overview of my academic and professional qualifications.
To summarize means to 'sum something up' or shorten it into conses form.
Certainly! Please provide a brief overview of the content you'd like summarized.
The word "summarize" is a verb that means to give a brief statement of the main points or key ideas of something. It is often used to condense information into a more concise form.
Briefly summarize the key points of the briefing and your general approach (is NOT the answer)
A detailed lesson plan will give information in detail about a lesson plan. A semi-detailed lesson plan will give information about a lesson plan but not as much as a detailed lesson plan. A brief lesson plan will mainly just give an outline of the lesson plan.
To summarize long book titles, focus on the main theme or subject of the book and condense it into a brief phrase or sentence. Highlight keywords, key characters, or central ideas to capture the essence of the book in a concise manner.
Recap is an abbreviation of recapitulate, to summarize in brief, originating in the 1920s particularly used in quickly and briefly broadcasting sports scores.
A summary of a paragraph, or anything else for that matter, is a brief account giving the main points of interest. It will be shirt, condensed, compact and succinct
