1. El Lipotón es un pigmento brillante y blanco que se utiliza en pinturas de interior de base acuosa y consiste en una mezcla de BaSO4 y ZnS. Cuántas moléculas se producirán de ZnS, si reaccionan 0,275 mol de ZnSO4 y 31,5 gramos de BaS al 85% de pureza, si la reacción tiene una eficiencia del 75% BaS (ac) + ZnSO4 (ac) → ZnS (s) + BaSO4 (s)

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
