1. You will be given a solution of silver nitrate from which to synthesize silver nanoprisms. The silver in the nanoprisms is Ag0. What do you need to do to the silver to get it into that form? Which would you use to do that: KBr, H2O2, NaBH4, sodium citrate? Why?

1. The citric acid cycle is a set of sequential reactions where 2 carbon atoms from Acetyl CoA (that derives from a glucose molecule) are coupled to a 4 carbon molecule. The carbon atoms from Acetyl CoA are released as CO2. Redox reactions and phosphorylation reactions are used to harvest energy in the form of ATP, NADH and FADH2. The product of these reactions is again a 4 carbon molecule that can be coupled with 2 carbon atoms from another...
