First phase of photosynthesis
WebApr 8, 2024 · Fig: Process of photosynthesis Plant leaves absorb the photons from sunlight that excite chlorophyll and activate electrons. In the first step, the water absorbed by plant roots is split into oxygen and hydrogen ions. Then the excited electrons from ATP and NADPH. This process happens through the electron chain. WebDec 24, 2024 · The light phase is the first phase of photosynthesis. It refers to the conversion of solar energy into chemical energy. Light is absorbed by complexes made up of chlorophylls and proteins called photosystems, …

WebAnswer (1 of 5): The first step involves an antenna complex absorbing a photon. An antenna complex is an assemblage of various molecules, including notably chlorophyll … WebWhen photosynthesis was stopped after two seconds, the principal radioactive product was PGA, which therefore was identified as the first stable compound formed during carbon dioxide fixation in green plants. …
WebIt is not light-dependent and takes place in chloroplasts, where the products from the previous stage are utilised. Once the CO2 is taken up by the plants, the Calvin Photosynthesis Cycle is initiated, during which the six molecules of CO2 are transformed into sugar or glucose. 3CO2+6NADPH+5H2O+9ATP → G3P+2H+6NADP+9ADP+8Pi. … WebStages of photosynthesis Stage one: light reactions This stage is so-called because it depends on light being available. The reactions of this stage also require specific enzymes to...
WebJun 8, 2024 · The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent … WebThe word photosynthesis can be broken down into its two parts: photo meaning light synthesis meaning to make So plants use light to make their own food (in the form of sugar). The overall...
Web12. The second stage of photosynthesis that produces sugar using ATP and NADPH is called the which occurs in the of the chloroplast. 13. CO 2 is taken in by the plant from the and will gain electrons in the Calvin Cycle to create 14. What molecule from the light-dependent reactions is needed as a source of energy for the Calvin cycle?
