Portage Learning Chem 210 - Module 7 Problem Set A scientist uses the term flux regarding a biochemical pathway. What does flux mean? Flux is the rate of flow through a biochemical pathway. A particular pathway breaks down proteins into amino acids. Is this an anabolic or a catabolic pathway? Catabolic. This is degradation of a molecule. The acetyl group is connected to CoA to make Acetyl-CoA. A) What specific atom of CoA connects to the carbon atom on the...

Portage Learning Chem 210 - Module 6 Problem Set What is the difference between a nucleoside and nucleotide? A nucleoside is formed from the covalent bonding of a base, purine or pyrimidine, to either ribose or 2-deoxyribose. Nucleotides are built from a nitrogen-containing organic base, a monosaccharide, and phosphate. What characteristic makes purines and pyrimidine heterocyclic? Each has a ring with nitrogen in the ring instead of all carbon atoms in the ring. ...
