The bacterium vibrio cholerae releases a toxin that blocks a channel protein in the membranes of cells that line the intestine. this toxin prevents the movement of sodium ions from the inside of the intestine into cells. if the sodium ions could not move into the cells, how would this affect the movement of water between the inside of the intestine and the cells? - water would leave the intestines and enter the cells by osmosis. - water would leave the intestines and enter the cells by facilitated diffusion. - water would leave the cells and enter the intestines by osmosis. - the movement of water would not be affected. - water would leave the cells and enter the intestines by facilitated diffusion.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
