Which of the following molecules are geometric isomers of each other?

Which of the following statements about protein-ligand binding is correct?

One of the enzymes involved in glycolysis, aldolase, requires Zn2+ for catalysis. Under conditions of zinc deficiency, when the enzyme may lack zinc, the enzyme would be referred to as the:

On human chromosome 11, the alpha (HBA) and beta (HBB) loci determine the structure of the 2 types of polypeptide chains in the heterotetrameric adult hemoglobin protein. Sickle cell anemia, a common form of sickle cell disease, is caused by a particular mutation in the HBB gene that results in the production of an abnormal version of beta-globin called hemoglobin S (or HbS). In this condition, hemoglobin S replaces both beta-globin subunits in hemoglobin. The mutation changes a single amino acid in beta-globin from glutamic acid to valine at position 6, causing the abnormal HbS subunits to stick together and form long, rigid molecules. The rigid HbS molecules bend red blood cells into a sickle (crescent) shape. The sickle-shaped cells die prematurely, which can lead to a shortage of red blood cells (anemia). The sickle-shaped cells can also block small blood vessels, causing pain and organ damage. Which of the following is the primary underlying reason for the aggregation caused by the HbS subunits?
