RuBisCO is one of many enzymes in the Calvin cycle. When Rubisco facilitates the attack of CO2 at the C2 carbon of RuBP and subsequent bond cleavage between the C3 and C2 carbon, 2 molecules of glycerate-3-phosphate are formed. The conversion involves these steps: enolisation, carboxylation, hydration, C-C bond cleavage, and protonation. WebbThe carriers in the electron transport chain use some of the electron's energy to actively transport protons from the stroma to the lumen. During photosynthesis, the lumen …

What Is Stroma? - Definition, Structure and Functions - BYJU
Webb1 Answer. Energy from an electron transport chain is used to actively transport protons from the stroma to the thylakoid lumen. Thus the lumen has a relatively higher proton concentration and therefore a lower pH than the stroma. Higher [H +] means lower pH. … WebbScience Biology In a photosynthetic investigation, a student measured the following pH of the stroma and the inner thylakoid compartments of spinach leaf cells at the conclusion … Webb19 nov. 2009 · So as hydrogen ions move into the thylakoid space from the stroma, hydrogen ions move from the cytosol into the stroma. This decreases the hydrogen ion … old songs archive.org
