Explanation:

• Transport and storage: Hemoglobin is a protein that transports oxygen in the blood and can be considered in the context of transport (and storage in a sense as it holds oxygen).
• Enzyme: Lactase is an enzyme that breaks down lactose (a sugar in milk). Enzymes are biological catalysts that speed up chemical reactions.
• Actin and myosin: These are contractile proteins. Actin and myosin interact to cause muscle contraction.
• Antibodies: Antibodies are proteins involved in the immune response. They recognize and bind to foreign substances (antigens) to help the body fight infections.
• Structural support/adhesion proteins: Collagen and fibrinogen are examples of structural support proteins. Collagen provides structural support in connective tissues, and fibrinogen is involved in blood clotting (a form of adhesion in the context of wound - healing).
• Protein on the surface of a cell: Receptor proteins are located on the surface of cells. They bind to specific molecules (ligands) and initiate a cellular response.

Answer:

• Transport and storage: Hemoglobin
• Enzyme: Lactase (breaks down lactose in milk)
• Actin and myosin: contractile proteins
• Antibodies: proteins involved in the immune response
• Structural support/adhesion proteins: collagen and fibrinogen
• Protein on the surface of a cell: Receptor
