Body Fluids And Circulation Question 4
Question: Given below are two statements:
Statement I: A protein is imagined as a line, the left end 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 ẞ type.)
In the light of the above statements, choose the correct answer from the options given below:
(1) Both Statement I and Statement II are true.
(2) Both Statement I and Statement II are false.
(3) Statement I is true but Statement II is false.
(4) Statement I is false but Statement II is true.
Show Answer
Answer: (4) Statement I is false but Statement II is true.
Explaination-
A protein is not imagined as a line with the N-terminal (amino terminus) on the left end and the C-terminal (carboxyl terminus) on the right end. In reality, the N-terminal is on the left side, and the C-terminal is on the right side when representing the amino acid sequence of a protein.
Adult human hemoglobin consists of 4 subunits: two subunits of α-type and two subunits of β-type. These subunits come together to form a complex protein structure responsible for carrying oxygen in the blood
