NADH produces 2.5 ATP whereas FADH2 produces only 1.5 ATP. Which of the following can reconcile this difference. Group of answer choices NADH transfers two electrons to the electron transport chain whereas FADH2 only transfers one. NADH transfers electrons to coenzyme Q through complex I a process that translocates four protons. FADH2 however transfers electrons to complex II which only translocates two protons. The reduction potential of NAD is lower than the reduction potential of FAD. NADH electrons go through the Q-cycle whereas electrons derived from FADH2 skip this cycle resulting in less proton translocation. None of the above can reconcile this difference.

Which of the following can be reduced by the use of renewable energy sources? a. social costs b. economic costs c. environmental costs d. all of the above select the best answer from the choices provided a b c d

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
