Egta is a substance that binds calcium ions. imagine an experimental setup with a motor neuron and a muscle fiber. stimulation of the motor neuron causes contraction of the muscle fiber through activity at the neuromuscular junction and excitation-contraction coupling. now, inject the muscle fiber with egta. which of the following effects would egta have on excitation-contraction coupling after the neuron releases acetylcholine at the neuromuscular junction?
a) it would prevent conduction of an action potential along the sarcolemma.
b) it would prevent the junctional folds from triggering an action potential.
c) it would prevent the release of calcium ions from the terminal cisterns.
d) it would prevent myosin from forming cross bridges with actin.

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell
