When levels of CO2 are experimentally increased, C3 plants generally respond with a greater increase in productivity than C4 plants. This is because

#Unit 10. Ecological Principles
  1. C   plants are more efficient in their use of CO2
  2. C   plants are able to obtain the same amount of CO2 by keeping their stomata open for shorter periods of time.
  3. C4 plants don’t use CO2 as their source of carbon.
  4. C3 plants are more limited than C4 plants by CO2 availability because of transpirational water loss.

Choose the correct statement
a. Hexokinases IV remains sequesters in the nucleus in case of high F-6-P and high ATP
b. Hexokinases IV remains sequesters in the cytoplasm in case of high F-6-P and high ATP
c. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is not ATP4- but the MgATP2- complex.
d. Hexokinase requires Mg+2 for its activity, because the true substrate of the enzyme is MgATP4- but not the MgATP2- complex.
