WebSep 16, 2024 · RUBP is present in the stroma. So, the dark reaction of photosynthesis takes place in the cytosol. What is the role of RuBP and Rubisco? RUBP Regeneration refers to the cyclical process where the photosynthetic enzyme Rubisco fixes carbon dioxide into the sugars that fuel plant growth and productivity. What is the main function of Rubisco? WebRegeneration of the CO2 acceptor molecule, RuBP is crucial if the cycle is to continue uninterrupted. The regeneration steps require one ATP for phosphorylation to form RuBP. …

WebJul 11, 2024 · Regeneration needs ATP and involves a complex series of reactions called the “carbohydrate scramble.” For one G3P molecule to exit the cycle and contribute to glucose synthesis, three CO2 molecules are required to enter the cycle, giving three new atoms of securely attached carbon. Weboverall goal of dark reactions incorporate CO2 into sugars (reduction) using chemical energy (ATP) and reducing power (NADPH) produced in light reactions part of the calvin-benson …
WebThey do, There are 6 5-carbon RuBP molecules (30C), which are broken into 6 3-carbon PGA molecules (18 C) and 6 2-carbon phosphoglycolate molecules (12C). These 2-carbon phosphoglycolate molecules are further broken up into 3 3-carbon PGA molecules (9C) and 3 1-carbon CO2 molecules (3C). WebPhotosynthesis is divided broadly into two main steps. Light Reactions: These reactions occur in the presence of sunlight and they are responsible for the generation of energy …
