The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. the energy from the electron transport chain is used for oxidative phosphorylation.

which compounds donate electrons to the electron transport chain?
h 2 o o 2 adp fad fadh 2 nadh atp nad +
which compound is the final electron acceptor?
adp nadh h 2 o o 2 nad + fadh 2 atp fad
which compounds are the final products of the electron transport chain and oxidative phosphorylation?
fadh 2 adp fad o 2 h 2 o nadh nad + atp

Which phase of the cell cycle ensures that identical copies of the dna are made for daughter cells?

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).

The law of thermodynamics states that energy can't be created or destroyed. to natural sources of energy on earth are the
