The electrons formed from the aerobic oxidation of glucose are
i. ultimately transferred to o2 after several other transfer reactions.
ii. transferred to the coenzymes nad and fad.
iii. directly transferred to o2 during the citric acid cycle.
iv. transferred to succinate and arachidonic acid.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
