Biomolecules

Given below are two statements:
Statement I: A protein is imagined as a line, the left and represented by first amino acid (C-terminal) and the right end represented by last amino acid (N-terminal).
Statement II: Adult human haemoglobin, consists of 4 subunits (two subunits of a type and two subunits of B type).
In the light of the above statements, choose the correct answer from the options given below:

Biomolecules

Statement I is false but Statement II is true

A protein is imagined as a line, the left end represented by the first amino acid and the right end represented by the last amino acid.
The first aminoacid is also called as N-terminal amino acid. The last amino acid is called the C-terminal amino acid.

Adult human haemoglobin consists of 4 subunits. Two of these are identical to each other. Hence, two subunits of α type and two subunits of β type together constitute the human haemoglobin (Hb).
