Hydrilla Photosynthesis Process As Biochemical Reducing Agent

Abstract

Photosynthesis is the process of synthesizing inorganic materials (CO2 and H2O) in pigmented plants with the help of solar energy. CO2 and H2O are substrates in photosynthesis reactions and with the help of sunlight and photosynthetic pigments consisting of chlorophyll and other pigments will produce iron and release oxygen. Basically, sequential reactions can be divided into two main parts, namely the light reaction (receives light) and the dark reaction (does not require light but requires carbon dioxide). Photosynthesis is influenced by many factors, both internal and external factors. Internal factors include the age of the leaves, the state of the stomata, and the type of plant. External factors include CO2 and O2, water availability, humidity and air temperature, light conditions. In the light reaction stage that occurs in the grana, light energy is shown to be energy consisting of NADPH2 and ATP. Then in the dark reaction stage, which is carried out in the stroma, NADPH2 and ATP are used as biochemical reducing agents to convert carbon dioxide into transport. Growing water releases oxygen into the air. The released oxygen will dissolve in the air and form dissolved oxygen. The photosynthesis practicum was carried out at the Microbiology and Molecular Biotechnology Laboratory, FPIK, Padjadjaran University. Performed on hydrilla plants.
