Answer:
It adjusts to different oxygen levels.
The cytochrome bo branch operates when E coli is growing rapidly with good aeration.
The cytochrome bd branch operates at low oxygen conditions. It is located in the outer membrane.
Explanation:
Electron transport chains of Escherichia coli are composed of different dehydrogenase and terminal reductase which is linked by quinones. It adjusts to different oxygen level because Oxygen is preferred electron acceptor and represses the terminal reductase of anaerobic.
Answer:
Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Explanation:
Humoral immunity is defined as the immunity which is mediated by several macromolecules presnet in the extracellular fluids such as antibodies, certain antimicrobial peptides, and complement proteins.
Humoral immunity allows to distinguishes two groups of foreign substances. it involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood. </u>
Humoral immunity begins when an antigens bind to B cells. Interleukins or helper T cells provides a secondary signal to the B cells that activates a B cell and allows B cell proliferation. which roduces produce plasma cells. The plasma cell then produces antibodies which are identical to the specific antigen. The antibodies are the released and circulate through the body, binding to antigens. B cells the further produces memory cellss for future immunity.
So, Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
