Choose the correct statements.
A) In ATPase enzyme F0 part is embedded in the membrane and forms a transmembrane channel
B) The F1 part of ATPase protrudes on the outer side of the membrane and a proton gradient is formed across the membrane
C) The gradient of the proton provides enough energy to cause a conformational change in F1 particle

Assertion (A): Relative concentration of Oand CO2 determines which of the two will bind to RuBisCO.
Reason (R): RuBisCO has a much greater affinity for CO2 than for O2.
