The protein of red muscles to store oxygen is:
Correct answer: C. Myoglobin
- A. Haemoglobin
- B. Myosin
- C. Myoglobin
- D. Actin
Explanation
Myoglobin is the correct answer because it is a protein found in muscle tissues that stores oxygen, providing a reserve that can be used during muscle contraction and periods of increased demand. While haemoglobin is involved in oxygen transport in the blood, it does not store oxygen within muscles. Myosin and actin are related to muscle contraction and cell structure, respectively, but do not have a role in oxygen storage.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
