In glycolysis, fructose 1,6-bisphosphate is converted to two products with a standard free-energy change (DG'°) of 23.8 kJ/mol.  Under what conditions (encountered in a normal cell) will the free-energy change (DG) be negative, enabling the reaction to proceed to the right?

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. If the concentrations of the two products are high relative to that of fructose 1,6-bisphosphate.

  2. The reaction will not go to the right spontaneously under any conditions because the DG'° is positive.

  3. Under standard conditions, enough energy is released to drive the reaction to the right.

  4. When there is a high concentration of fructose 1,6-bisphosphate relative to the concentration of products.

A. Mid of the day stomatal aperture has a largest diameter, water loss and transpiration rate will be highest at the  same time

B. In mid of the day incident light is highest in terms of PPFD and can also say CO2 diffusion will be highest

C. The stomatal aperture has a largest diameter resulting closing of stomatal pore, water loss and transpiration rate will be lowest due to closing of stomata

D. In mid of the day incident light is highest in terms of PPFD resulting CO2 will not diffuse

which of the following combination from the given graph will be CORRECT?
