Question

Which one of the following is wrongly matched?
A. Fungi – Chitin
B. Phospholipid – Plasma Membrane
C. Enzyme – Lipopolysaccharide
D. ATP – Nucleotide derivative
E. Antibody – Glycoprotein

Answer 1

Hint: Chitin is found in the cell walls of some members of Kingdom Mycota. The Plasma membrane is made up of bilayered phospholipids. Enzymes are biocatalyst proteins and RNA. ATP contains Adenine. Moreover, antibodies consist of proteins and gamma globulins.

Complete answer: 

Let us look at all the pairs that are given to us one by one.
Fungi – Chitin: The cell wall for most of the Fungi is made up of cellulose. However, the cell wall of some Fungi is also made up of Chitin. Due to this reason, the Chitin is also known as the Fungal cellulose. The cell wall of Chitin is found in the members of the class of Zygomycetes of the Kingdom Fungi. Zygomycetes are also known as the Conjugation fungi. Examples of Zygomycetes are Rhizopus, Mucor, etc.
Phospholipid – Plasma Membrane: The plasma membrane is the living membrane. It is selectively permeable in nature. The Plasma membrane is made up of proteins and lipids. Therefore, it is collectively known as lipoproteins. The structure of the Plasma membrane is made up of bilayered phospholipids.
Enzyme – Lipopolysaccharide: Enzymes are the chemicals that are the biocatalysts. Enzymes are made up of proteins only. Only some enzymes are made up of RNA due to which they are known as the Ribozymes.
ATP – Nucleotide derivative: ATP stands for Adenosine triphosphate. ATP is made up of a nitrogenous base of Adenine, a ribose sugar, and three molecules of the phosphate of the triphosphate. Adenine is a nucleotide base. Therefore, ATP can also be called a nucleoside triphosphate. Hence, it is a nucleotide derivative.
Antibody – Glycoprotein: Antibodies are immunoglobulins. Antibodies are produced in response to the antigenic stimulations. Antibodies are glycoproteins. This is because they are made up of gamma globulins and blood proteins. Antibody molecules are usually made up of two small light chains and two large heavy chains.
Thus, based on the above information we can conclude that Enzyme – Lipopolysaccharide is the wrongly matched pair.

Hence, the correct answer is option (C).

Note: Enzymes are made up of the protein and the Non-protein part. The protein part is known as Apoenzyme. The Non-protein part is known as the Coenzyme or the Co-factor. The co-factor can further be organic or inorganic compounds.
