The illustrations below show the creation of two different mixtures. Based on this information, decide which conclusion is supported by the evidence you have been given. Only Mixture A resulted in a chemical reaction. Only Mixture B resulted in a chemical reaction. Both Mixture A and Mixture B resulted in chemical reactions. Neither Mixture A nor Mixture B resulted in a chemical reaction.

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
