Globulin proteins are found in:
Correct answer: D. Both A and C
- A. Animals
- B. Plants
- C. Human beings
- D. Both A and C
Explanation
Globulin proteins are primarily found in animals, including humans, where they perform critical roles in the blood plasma. These roles include the transportation of lipids and ions, acting as antibodies, and being part of the immune system. Option D is correct because it acknowledges that globulins are present in both animals and humans. Option A and C are individually correct but incomplete when considering the broader categorization that includes humans as animals. Option B is incorrect as globulin proteins are not typically associated with plant systems.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
