Photosynthesis

Photosynthesis & Chemical Respiration.
Basic Chemical Reactions:
* Photosynthesis:
Solar energy + 6CO2 + 6H2O-------6O2 + C6H12O6

* Cellular Respiration:
C6H12O6 + 6O2---------6H2O+6CO2 + 38 ATP

Photosynthesis:
Photosynthesis is the process in which plants and other organisms convert the light energy captured from the sun into chemical energy that can be used to fuel theorganism's activities using carbon dioxide and water and releasing oxygen as a waste product.
 The process always begins when energy from light is absorbed by proteins. In plants, these proteins areheld inside organelles called chloroplasts. Some of the light energy gathered by chlorophylls is stored in the form of ATP and the rest of the energy is used to remove electrons from a substance suchas water. These electrons are then used in the reactions that turn carbon dioxide into organic compounds. Carbon dioxide is converted into sugars in a process called carbon fixation.
Photosynthesisoccurs in two stages:
First stage:  Light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP.
Second stage:The light-independent reactions use these products to capture and reduce carbon dioxide.
In other words, Photosynthesis changes sunlight into chemical energy, splits water to liberate O2, and fixes CO2 into sugarand the organelle in which this occurs is the chloroplast.
Cellular respiration.
It’s a compilation of chemical processes and metabolic reactions that are in charge of converting energy fromnutrients into ATP and throw away waste products (CO2).
Respiration is one of the key ways a cell gains useful energy to fuel cellular activity.
Cellular respiration is the process by which biologicalfuels are oxidised in the presence of an inorganic electron acceptor (such as oxygen) to produce large amounts of energy, to drive the bulk production of ATP.
