Metabolism correct answer: The totality of the chemical reactions that take place in living organisms. Metabolic Pathways correct answer: A sequence of steps, each controlled by an enzyme, that convert a specific molecule to a product. Catabolic Pathways correct answer: Release energy stored in complex molecules by breaking them down into simpler compounds. Anabolic Pathways correct answer: Require energy to combine simpler molecules into more complicated ones. The energy released i...

An antigen can induce an immune response in a host organism. Antigens are targeted by antibodies that are produced by the organism's immune system in response to contact with the antigen. Antibodies are specific to antigens. Many different cell types are involved in immune responses. Which of the following best describes the role of cell-to-cell communication during a response to an invasion of antigens? A Chemicals that are secreted from antigen-presenting cells then activate helper T cells...
