write structural formulas for all the ionic forms of glutamic acid, and calculate its isoelectric ph.
Assume that in a certain cell, the ratio of products/reactants or Keq = 894.2 (Keq is dimensionless) for the reaction Glucose + ATP <> Glucose-6-P + ADP, at a particular instant, the concentrations of each compound were Glucose =2.2M, ATP =9.6M, ADP =10.3M and G-6-P =23.7M. Calculate the difference (dimensionless) between Keq and the ratio of products/ractants at this instance, in this cell, to five significant figures.

- Below are described three methods through which breads are leavened (risen). Which of them are chemical changes? 1. Yeast breads: Yeast added to flour and water digests carbohydrates from the flour and produces carbon dioxide (CO2) which forms bubbles in the flour water mixture. 2. Quick Breads: Flour, water, baking soda (NaHCO3) and a source of acid, are mixed and baked. The baking soda interacts with acids and heat in the batter to release carbon dioxide (CO2) gas, forming bubbles in the mixture. 3.
