QUESTION 10 Cancer is often caused by mutations in transmembrane receptors that allow the receptor to activate the signal cascade in the absence of signaling molecules An antibody that prevents specific transmembrane receptors from undergoing conformational changes is being tested for its effectiveness in preventing cancer. At which stage does this drug work? O alt prevents the receptor from bonding to the signal. O b. It prevents the signaling cell from producing the signal It prevents the termination of the signal O d. It prevents the receptor from transmitting the signal QUESTION 11 Membranes exposed to very low concentrations of detergent become leaky to small molecules and ions. However, at these concentrations of detergent proteins remain intact and functional . In an experiment, an inolted mitochondrin is exposed to detergent and the molecules of the ETC and of ATP synthe remain intact. Do you expect ATP synthexis to continue in the presence of low concentrations of deteryent? O. Yes, because all entrymes and electron carriers remain intact. ob No, because lenky membranes do not allow NADH and FADH2 to donate their electrons to the electron trzewport chain. O. No, because with a lenky membrane, the proton gradient cannot be maintained Od.No, because leaky membranes inhibit glycolysis
