The cytochrome b6f complex of the photosynthetic electron transport system is responsible for translocating 8 H+ into the thylakoid space from the stroma. However, a total of 12 H+ accumulate inside the thylakoid space as a result of photon absorption by PSII and PSI. What is the origin of the other 4 H+? correct answers The oxidation of 2 H2O to form O2 + 4 H+ + 4 e- Raffinose-series oligosaccharides are hard for humans to digest because correct answers humans do not have the enzyme necessar...

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 ...
