Top 3 Stages of Calvin Cycle (With Diagram)

Let us make an in-depth study of the three stages of Calvin cycle. The three stages are: (a) Carboxylation (b) Reduction and (c) Formation of Hexose Sugar and Regeneration of RuBP. The Calvin cycle (C3-cycle) or PCR-cycle can be divided into three stages: (a) Car-boxylation, during which atmospheric CO2 combines with 5-C acceptor molecule ribulose 1, 5-bisphosphate (RuBP) and converts [...]

Blackman’s Law of Limiting Factors and his Criticism | Photosynthesis

In this article, we will discuss about 1. Illustration of Blackman's Law of Limiting Factors and 2. Criticism of the Blackman's Law of Limiting Factors. Illustration of Blackman's Law of Limiting Factors: It had been used to study the effect of individual factors on the rate of photosynthesis in terms of minimum, optimum and maximum (the three cardinal points). Ear­lier [...]

Evidences for the Calvin Cycle | Photosynthesis

The following points highlight the four evidences for the Calvin cycle. The evidences are: 1. Evidence from Studies of Variation of Labeling of Intermediates with Time by Em­ploying Radioactive 14CO2 2. Evidence from the Labeling Pattern of the Carbon Chain in the Intermediates 3. Evidence from Changes in the Steady-State Levels of Intermediates and 4. Evidence from Isolation of the Enzymes. [...]
