Which Path Could a Carbon Atom Follow If It Began

Multiple Choice

Which path could a carbon atom follow if it began in an amino acid in a protein in some tuna that was eaten by a cat and eventually ended up in a lipid in the cell membrane of one of the cat's muscle cells?

A) Amino acid citric acid cycle acetyl CoA fatty acid triglyceride cell membrane
B) Amino acid  acetyl CoA  citric acid cycle pyruvate oxidation cell membrane
C) Amino acid pyruvate oxidation gluconeogenesis glucose glycerol triglyceride cell membrane
D) Amino acid  electron transport  citric acid cycle acetyl CoA lipid cell membrane
E) Amino acid  citric acid cycle acetyl CoA pyruvate glycolysis glycerol  triglyceride cell membrane
