Question 1 2.5 / 2.5 pts Indicate whether each of the following descriptions better applies to COPI- (1), COPII- (2), or clathrin- (3) coated vesicles. Your answer would be a four-digit number composed of digits 1 to 3 only, e.g. 1322. ( ) They mediate transport from the ER to the cis Golgi network. ( ) Their coat protein forms a three-legged structure called a triskelion. ( ) They are pinched off from their donor compartment by a dynamin collar. ( ) They are involved in retrograde trans...

Why is celecoxib selective for COX-2 inhibition as compared to COX-1 inhibition? COX-1 contains Ile-523, whereas COX-2 contains Val-523, which permits celecoxib binding. COX-1 contains Ile-523, whereas COX-2 contains Val-523, which blocks celecoxib binding. COX-1 contains Val-523, whereas COX-2 contains Ile-523, which permits celecoxib binding. COX-1 contains Val-523, whereas COX-2 contains Ile-523, which blocks celecoxib binding. COX-2 is located in the endoplasmic reticulum where ...

2 ways phosphate addition/removal causes conformational changes - Answer 1)Phosphorylation has a lot of negative charges that interfere with interactions between substrates --> forces protein into different conformations 2) phosphorylation of an enzyme can also alter substrate-binding affinity via electrostatic repulsion what happens to the GPCR and g-protein when a hormone reaches the GPCR receptor on cell membrane? - Answer hormone triggers a conformational change in receptor, which s...

Made this summary for DRUG TARGETS BIOCHEMISTRY AND SIGNALING. Summary is detailed and complete. However, chapter 11 and 12 were not saved correctly. These are lost. I had a printed backup which is scanned and included in this summary. The quality is the same as the rest of the summary. The only thing is that it is scanned and 2 on 1 side (still readable).
