Final answer:

Proteins are categorized based on their functions, including enzymes, structural, transport, storage, hormonal, receptor, contractile, and defensive proteins. Examples include amylase, collagen, hemoglobin, ferritin, insulin, and antibodies.

Step-by-step explanation:

Proteins serve various functions crucial to organisms and fall into different categories based on their roles:

  • Enzymes: These proteins act as catalysts to speed up chemical reactions, with examples including amylase and trypsin.
  • Structural: These proteins form the infrastructure of cells and tissues, such as collagen in connective tissues and keratin in skin and hair.
  • Transport: Transport proteins like hemoglobin carry oxygen in the blood and albumin helps in the transport of various substances.
  • Storage: Storage proteins such as ferritin and ovalbumin store nutrients or essential chemicals.
  • Hormonal: Hormone proteins like insulin and growth hormones regulate various physiological processes.
  • Receptor: Receptor proteins on cell surfaces receive and transmit signals to the cell.
  • Contractile: These proteins, including actin and myosin, are responsible for muscle contraction and movement.
  • Defensive: Proteins like antibodies play a critical role in the immune response by identifying and neutralizing pathogens.

Each type of protein has a unique role in maintaining the health and function of organisms.
