Which of the following statements is False about Rubisco?

#Unit 6. System Physiology – Plant
  1. Rubisco appears to have evolved from an ancient enolase in archaea methionine-salvage pathway

  2. The turn over number of rubisco is high in terms of carboxylation can only fixes 1 to 12 CO2 molecules per sec

  3. Rubisco is made up of eight nucleus encoded small subunits and eight plastids encoded large subunits
  4. Oxygenase activity of rubisco takes place at high temperature where its  affinity for CO2 reduces significantly

The graph below shows  the  growth  rates  of  populations  of  bacteria  that  have  evolved  for  many  generations  at different culture temperatures (25°C, 30°C, and 35°C). Each population grows over only a limited range of temperatures (its thermal niche), which are bounded by its critical thermal limits. Within this range, growth rate increases with temperature up to a maximal value and then declines rapidly with increasing temperature. Growth rates are known to be the major determinant of fitness for these bacteria.

Which of the following is true concerning the thermal dependence of growth rate   between 25°C and 30°C in these populations?
