1. Branched chain amino acids are directly used for fuel in which tissues: a. muscle b. brain c. kidney d. all the above 2. Biological reactions with a positive delta G can spontaneously occur when coupled to another reaction that is thermodynamically favorable because: a. it has a larger and negative delta G b. it produces molecules with lower freedom of electron motion. c. it is catalyzed by an allosteric enzyme d. it has a larger and negative delta S 3. What is the total and net number of ATP molecules that will be produced by glycolysis in a red cell starting from 1 molecule of fructose-6-phosphate? a. 4 total and 3 net ATP b. 3 total and 2 net ATP c. 4 total and 1 net ATP d. 4 total and 2 net ATP

Step 1
Branched chain amino acids are primarily used for fuel in muscle tissue, as they can be directly metabolized in the muscle rather than in the liver like other amino acids. So the answer for the first question is: $\boxed{\text{a. muscle}}$ Show more…
