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.

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.
