✦ Synopsis

The induction of sporulation in yeast is generally accompanied by a sharp increase in energy metabolism which is evidenced by a rise of the adenylate energy charge by that time. The energy charge can be held at a low level by limitation of the phosphate supply in the growth medium. Ascus formation remains unaffected by this treatment. This suggests that the rise in ATP production normally encountered during early sporulation is not essential for the initiation of sporulation.

The phosphate potential (A G'p) and the proton motive force (Ap) were recorded simultaneously in Streptococcus cremoris under different conditions. If thermodynamic equilibrium exists the ratio A G'p/A p gives the number of protons translocated by the ATPase per ATP hydrolyzed or synthesized. In res
