In this article we will discuss about the Photochemical and Biosynthetic Phase of Photosynthesis. Photochemical Phase (Light or Hill Reaction): It occurs inside the thylakoids, especially those of grana region. Photochemical step is dependent upon light. The function of this phase is to produce assimilatory power consistÂing of reduced coenzyme NADPH and energy rich ATP molecules. Photochemical phase involves the [...]
The upcoming discussion will update you about the differences between Photosystem I and Photosystem II. Difference # Photosystem I: 1. The system is located in the non-appressed part of grana thylakoids as well as stroma thylakoids. 2. Chlorophyll: carotenoid content is high. 3. Chlorophyll a content is more than twice that of chlorophyll b. 4. Its photo Centre is P70C. [...]
In this article we will discuss about:- 1. Photosynthesis as Means of Autotrophic Nutrition 2. Magnitude of Photosynthesis 3. History. Photosynthesis as Means of Autotrophic Nutrition: Only photosynthesis is a means by which certain organisms can manufacture their own organic food from inorganic raw materials with the help of solar energy. The organisms performing photosynthesis are, therefore, called autotrophs or [...]
