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 spontaneously to the right?

#Life Sciences

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

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

  3. The reaction will proceed spontaneously to the right if there is a high concentration of products relative to the concentration of fructose 1,6-bisphosphate.

  4. The reaction will proceed spontaneously to the right if there is a high concentration of fructose 1,6-bisphosphate relative to the concentration of products.

Q. Consider the following statements regarding cytoplasm transfer via somatic hybridization:
Statement I: Cytoplasm transfer that normally takes 6–7 years via backcrossing can be achieved in just one year using protoplast fusion.
Statement II: Iodoacetate is used to inactivate the nucleus of the recipient parent protoplasts.
Statement III: Irradiation of donor protoplasts is used to inactivate their nuclei.
Statement IV: The resulting cybrids contain the nucleus of parent A and mitochondria of parent B.
