The direct energy source that drives atp synthesis in respiratory oxidative phosphorylation in eukaryotes is the proton-motive force across the inner mitochondrial membrane. Be able to understand the steps, the concepts, and the result of it. Lysosomal enzymes released from the dying cell can damage neighbouring cells. As part of osmoregulation, the adrenal glands can secrete a chemical messenger to signal the kidneys to increase ion and water reabsorption. Inhibitory subunit turns off adenylate cyclase no more camp produced. Trying to reduce releasing growth factor by producing less of it. Something needs to interrupt import because e want to leave this protein as spanning the membrane. Translocating complex recognizes pattern of amino acids (hydrophobic so that it will stay in the protein) Will stop import but ribosome will continue to translate it. Stays in the membrane for as long as it does its task in the membrane. Different parts of a gene and its structure.
