Calculating gross photosynthesis in C3 and C4 metabolisms

Photosynthesis is the main metabolic process for guaranteeing life on earth, through energy transfer relationships in the food chain. Studying this magnificent process is an immense privilege for those who have it. Nowadays, the carbon balance has gained a lot of space regarding the photosynthetic characterization of species, but its use can mask the real results of photosynthesis, which by the way is a process of energy production and transport. Therefore, this work aimed to develop a logical reasoning, through simple equations, to calculate the energy produced during the species cycles of C3 and C4 metabolisms, based on the volume of water absorbed and transpired by the plant.
