Four electron carriers, a, b, c, and d, whose reduced and oxidized forms can be distinguished spectrophotometrically, are required for respiration in a bacterial electron-transport system. in the presence of substrates and oxygen, three different inhibitors block respiration, yielding the patterns of oxidation states shown below. what is the order of the carriers in the chain from substrates to o2, and where do the three inhibitors act?

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

the answer is c.mitochondria. glad to .

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
