Physiology & Pathophysiology Module 1- Membrane Physiology & Action Potentials (Long) Questions And Answers (A+ Grade) 1. Explain the structure of the membrane - ANS-Cell Membranes are composed primarily of lipids and proteins. Lipids consist of phospholipids, cholesterol, glycolipids - high permeability of membranes to lipid soluble substances (CO2, fatty acids, steroid hormones). Lips are also responsible to the low permeability of water-soluble molecules (ions, glucose, amino acid...

Chem and Physics section - correct answer What atom is the site of covalent attachment of AMC to the model tetrapeptide used in the studies? - correct answer Because AMC is attached to the peptide on the carboxyl side. This suggests that an amide linkage involving the N atom in AMC is used to covalently attach the fluorophore to the peptide *a peptide bond between amino acids= covalent bond between carboxyl group of 1 amino acid to amino group of other, releasing water What express...

When more enzyme is added to a reaction involving a regular enzyme, the Vmax ________ in the presence of available substrate. (Inhibitors are not a factor in this situation) Correct Answer-Decrease An increase in Km indicates that ____ substrate is required for an enzyme to bind substrate. Correct Answer-More The folding of the tertiary structure is due to Correct Answer-Hydrogen, hydrophobic, and disulfide bonding among distant amino acids The ______ structure of the secondary level of...
