Final answer:
Examples of proteins include antibodies, enzymes, and hemoglobin. DNA and RNA are not proteins but nucleic acids that are involved in the storage and processing of genetic information and the synthesis of proteins. (a) Antibodies, (c) Enzymes, (e) Hemoglobin
Step-by-step explanation:
When addressing the question of which of the listed items are examples of proteins, it is essential to understand the role and composition of proteins within biological systems. Proteins are large, complex molecules that play critical roles in the body and are the final products of gene expression. Made up of amino acids, proteins perform a vast array of functions including catalyzing metabolic reactions (enzymes), defending against pathogens (antibodies), and transporting molecules such as oxygen (hemoglobin).
The following are examples of proteins:
- Antibodies are proteins that are part of the immune system and help protect the body against disease.
- Enzymes are proteins that act as biological catalysts to speed up chemical reactions in the body.
- Hemoglobin is a protein found in red blood cells that transports oxygen throughout the body.
On the other hand, DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid) are not proteins; they are nucleic acids, which are different types of biological molecules that store genetic information and are involved in the synthesis of proteins.
