WebIn dark conditions, Rubisco is present in an inactive form in the stroma of the chloroplast. This is because the shape of the enzyme is pH dependent. The enzyme is activated when the pH in the stroma increases (due to a decrease in concentration of H+ ions). (2 pts) (A) What photosynthetic process leads to the increase of pH in the stroma? WebWährend sich der pH-Wert des Thylakoidinnenraumes bei Belichtung in den sauren Bereich verschiebt (pH-Wert 5), wird im Stroma, welches die Thylakoidmembranen umgibt, die Konzentration an Protonen geringer, da Protonen bei der Bildung des Reduktionsmittels NADPH + aus dem Stroma verbraucht werden.
Web1 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. … WebFrom Figure 6.20 in our textbook of part of a chloroplast, suppose the pH in the Stroma = 3.0 and the pH in the Lumen = 8,0. In addition, suppose the electric potential in the Stroma = 70 mV more positive than in the Lumen. (a)What is the chemical potential difference (Au) for H+(Stroma) - H+(Lumen)? (b) Calculate the AG if a total of 3 moles ...
WebAug 11, 1975 · The pH in the stroma and in the thylakoid space has been measured in a number of chloroplast preparations in the dark and in the light at 20 degrees C. Illumination causes a decrease of the pH in the thylakoid space by 1.5 and an increase of the pH in the stroma by almost 1 pH unit. 2. CO2 fixati … WebThe pH of the inner thylakoid space has been measured, as have the pH of the stroma and of the cytosol of a particular plant cell. Which, if any, relationship would you expect to find?A. The pH of the stroma is lower than that of the other two measurements.B. The pH within the thylakoid is less than that of the stroma.C.
