A four-cell embryo normally develops into a blastocyst consisting of trophectoderm (TE) cells on the outside and inner cell mass (ICM) cells inside. The transplantation experiments were done with mouse embryos.

A. If a labeled cell is placed on the outside of a very early embryo, it is likely to form extraembryonic tissues.

B. If a labeled cell is placed on the inside of a very early embryo, it is likely to form embryonic tissues.

For the reaction catalyzed by the enzyme hexokinase: Glucose + ATP → glucose 6-phosphate + ADP the equilibrium constant, Keq, is 7.8 × 10². In living E. coli cells, [ATP] = 5 mM, [ADP] = 0.5 mM, [glucose] = 2 mM, and [glucose 6-phosphate] = 1 mM. Which of the following conclusions made on the basis of the above calculations is incorrect?
