The Janus Green B stain should allow you to see mitochondria within the cells obtained from your cheek sample. Describe below the observations you made about the number of mitochondria per cell and their relative distribution and size within the cytoplasm of cheek cells. Compare and contrast what you observed with the prepared slide you observed in Section E4 for Liver mitochondria. What function do mitochondria have within cells?

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.

Why has two different alleles for the same trait?
