Biochem Final Exam Questions and Answers with Verified Solutions How do prion proteins differ from traditional infectious agents? Prions are misfolded proteins that can induce misfolding in other proteins, leading to diseases without nucleic acids, unlike traditional pathogens. What is the purpose of the Krebs cycle in cellular respiration? The Krebs cycle generates electron carriers (NADH and FADH2) and ATP while oxidizing acetyl-CoA, contributing to energy production. How does ...

What is the basic structure of an amino acid? What do they look like? - amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? - ionic, hydrophobic/non- pola...

Differentiate between complete and incomplete proteins and provide typical sources of each. Complete proteins: Have all nine essential amino acids. Ex. Animal sources of protein (milk, meat) Incomplete proteins: Lack one or more of the essential amino acids. Ex. Plant sources of proteins (legumes) Describe the molecular structure of proteins and the four levels of protein structure. Which bonds are essential to each level of organization? Proteins are composed of long chains of amino acid...
