Oxygenic Photosynthesis
Carbon dioxide + Water + solar energy → Glucose + Oxygen
6CO 2 + 6H 2 O + solar energy → C 6 H 12 O 6 + 6O 2
Carbon dioxide + Water + solar energy → Glucose + Oxygen + Water
6CO 2 + 12H 2 O+ solar energy → C 6 H 12 O 6 + 6O 2 + 6H 2 O
Anoxygenic Photosynthesis
CO 2 + 2H 2 S + light energy → (CH 2 O) + H 2 O + 2S

Content: This Law states that the rate of a physiological process will be limited by the factor which is in the shortest supply. In the same way, the rate of photosynthesis is also affected by a number of factors, which are namely; Light
As the intensity of light increases, the rate of light-dependent reactions of photosynthesis and in turn, the rate of photosynthesis increases. With increased light intensity, the number of photons falling on a leaf also increases. As a result, more chlorophyll molecules are ionized, and more ATPs and NADH are generated. After a point, however, the rate of photosynthesis remains constant as the light intensity increases. At this point, photosynthesis is limited by some other factors. Besides, the wavelength of light also affects the rate of photosynthesis. Different photosynthetic systems absorb light energy more effectively at different wavelengths. Carbon dioxide
An increase in the concentration of carbon dioxide increases the rate at which carbon is incorporated into carbohydrates in the light-independent reactions of photosynthesis.
