Let us make an in-depth study of the mechanism of bacterial photosynthesis. After reading this article you will learn about (A) Light Reaction and (B) Carbon Assimilation. (A) Light Reaction: In contrast to algae and higher plants which are oxygenic (i.e., they evolve O2 during photosynthesis and have two photo-systems that act in tandem or series, the photosynthetic bacteria are [...]
In this article, we will discuss about the crassulacean acid metabolism (CAM) and dark CO2 fixation. Under natural conditions the acidity of green shoots of some non-halophytic succulents and semi-succulent plants increases at night and decreases during the following day. This diurnal change in acidity was first discovered in a Crassulacean plant Bryophyllum calycinum hence, it has been termed as [...]
In this article, we will discuss about the Rubisco-universality occurring enzyme of all photosynthesizing plant. Rubisco or ribulose bisphosphate carboxylase/oxygenase is universally occurring enzyme of all photosynthesizing plants except few photosynthetic bacteria. In eukaryotes, it is exclusively found in chloroplast stroma and is so abundant that it represents about 40% of the total soluble protein of most leaves. According to [...]
