Document Summary
Number of amino acids to span the 3nm thick membrane of the cis-golgi. A. as alpha helix: 20 amino acids. 1 turn = 0. 54 nm i. ii. iii. Predicting to see if proteins have a transmembrane domain a. Charged aa can be present in hydrophobic regon a. Bacteriorhodopsin: light-driven proton pump of bacteria, 7 transmembrane domains. Conformational change: determined by interactions between each aa b. Posttranslational modification ph, voltage, temp: transporters i. ii. iii. iv. Highest speed (107-108) i: has numerous binding sites. Relate to slope of vmax chart: concentration gradient is in constant struggle with the electrochemical gradient. Glucose transporter that moves glucose from the blood across the. Measure how much glucose is inside the liposomes: carriers that transport against electrochemical gradient. Ions & membranes i. ii: na+/k+ pump. Provides gradient to power other carriers i. i. i. ii. iii. i. i. ii. iii. iv. i. ii.
