Final answer:

Hemoglobin is not a pentamer; it is a tetramer consisting of four globin proteins, making statement b) false.

Step-by-step explanation:

The question relates to the properties of globins, which are proteins involved in oxygen transport and storage in various organisms. The false statement is that "Hemoglobin is a pentamer" because, in reality, hemoglobin consists of four globin proteins, each bound to a molecule of heme. Myoglobin is indeed a monomer; leghemoglobin can be found in plants, particularly in the root nodules of leguminous plants; all globins carry oxygen as part of their biological function, and they all contain heme, which is essential for their oxygen-carrying capacity.
