Aquaporins are a specialized channel for the movement of water molecules through a membrane. What is one of their critical properties? correct answers They allow only water to pass, and use strategically placed Asn residues to prevent proton passage. The biomolecules responsible for facilitating small molecule transport across membranes are: correct answers proteins What prevents other positively charged ions from passing through a K+ channel? correct answers The structure of the K+ channe...

Define Km in MM kinetics: - ANSWER-The concentration of substrate [S] at which 1/2 Vmax is reached Km is _________ related to affinity of the enzyme for its substrate - ANSWER-inversely Vmax is directly proportional to what? - ANSWER-to the enzyme concentration What characterizes MM kinetics? - ANSWER-a hyperbolic curve when Vmax is plotted against [S].
