Accepts electrons from cytochrome c, ultimately transferring them to oxygen, forming H2O. in the process, 2 protons are pumped across the membrane. Complex IV is a terminal oxidoreductase, meaning that it transferes the elctrons to the terminal electron acceptor, which, in this case, is O2.
White blood cells called lymphocytes originate in the bone marrow but migrate to parts of the lymphatic system such as the lymph nodes, spleen, and thymus. There are two main types of lymphatic cells, T cells and B cells.
A group of white blood cells called lymphocytes plays a key role in the human immune response. Lymphocytes include cells called B-cells and T-cells that are responsible for flagging and fighting infections in healthy individuals.Antigens are substances that elicit the response of T-cells and B-cells in the body.When a T-cell recognizes a specific antigen, it binds to the substance and produces chemicals called cytokines. group of white blood cells called lymphocytes plays a key role in the human immune response.
