Question

explain what RuBisCo is and what its role is in producing glucose

explain what the proton motive force is and how the proton motive force is created

Answer 1

Answer 1:-

RuBisCO enzyme is found in chloroplasts, that is used during photosynthesis to fix atmospheric carbon dioxide and during photorespiration in oxygenation of the resulting compound.

RuBisCO catalyzes a reaction between CO2 and RuBP, which forms a six-carbon compound that is fastly converted into two three-carbon compounds. called carbon fixation in which CO2 is fixed from its inorganic form into organic molecules.stored energy is used by ATP and NADPH to convert the three-carbon compound, 3-PGA, into another three-carbon compound called G3P. process callled reduction reaction as there is the increase of electrons.The molecules of ADP and NAD+, resulting from the reduction reaction, return to the light-dependent reactions to be re-energized.One of the G3P molecules leaves the Calvin cycle to help in formation of carbohydrate molecule, which is commonly glucose (C6H12O6)

Answer 2:-

The energy-rich, unequal distribution of protons established across the membrane is called proton motive force.

The proton motive force generate when the cell membrane becomes energized by the electron carriers embedded in it due to electron transport reactions this causes the cell to act like a tiny battery. Its energy can either be used to do work, like power flagella, or be stored for later in ATP.

please give a thumbs up if the answer help you. Thank you!
