List the following in order of increasing tendency to accept electrons: (a) α-ketoglutarate + CO2 (yielding isocitrate); (b) oxaloacetate; (c) O2; (d) NADP+.
The second step in the catabolism of most amino acids is the removal of the nitrogen atom from glutamate by oxidative
deamination. In this reaction, glutamate is converted to an a-keto acid.
Modify the structure to show the a-keto acid product.

Assume that in a certain cell, the ratio of products/reactants or Keq = 747.1 (Keq is dimensionless) for the reaction Glucose + ATP <> Glucose-6-P + ADP, at a particular instant, the concentrations of each compound were Glucose =2.0M, ATP =7.7M, ADP =10.2M and G-6-P =21.5M. Calculate the difference (dimensionless) between Keq and the ratio of products/ractants at this instance, in this cell, to five significant figures.
