Background information: Photosynthesis is the process where water, carbon dioxide, and light go into the chloroplast and produce glucose and oxygen. In photosynthesis there are two main parts there are the light reactions and the calvin cycle. In the light reactions water and light go into the thylakoid membrane and produce ATP, NADPH, and oxygen as a waste product. Since oxygen is considered a waste product, it is removed from the plant cell by leaving through the stoma of the plant. The light first of all powers the photosystems which allows for ions to be pushed through the electron transport and produce ATP. This is because since the ions have been pushed all the way to end of the cycle they go through ATP synthase and every time a few ions go through ATP is produced. But, also during this water is introduced but is broken down into oxygen and released. The formula for photosynthesis is 6H 2 O + 6CO 2 +Light---> C 6 H 12 O 6 +6O 2 so, so far ATP has been produced (energy), and oxygen.Which shall be carried to the calvin cycle. In the calvin cycle products from the light reactions (ATP) are providing energy to power the calvin cycle. In the calvin cycle Ribulose which is 5 carbon molecule comes and get attached to a Co 2 molecule and breaks into a 3 carbon molecule and gets energy from ATP and NADPH and when done forms G 3 P which can be reused and forms glucose. In photosynthesis there are three main factors affecting the rate of photosynthesis these are light, water, and carbon dioxide. These things all need to be balanced out

though for example if a very high concentration of light is given to a specimen the rate of photosynthesis will not change if there is not enough carbon dioxide or water to sustain for a higher rate of photosynthesis But, if the environment and conditions allow it then the rate of photosynthesis will go up.Which in this experiment would release more air bubbles. This would be because if the rate of photosynthesis is up then the process where water is divided into oxygen and released as waste will happen more often and will release more air bubbles. Also another thing that can cause for the rate of photosynthesis to stay the same or even decrease is that with the light concentration being increased that could cause a decrease in the amount of water which eventually would balance itself out and not have a very significant increase in rate of photosynthesis. Another factor that

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
