Explain why early eukaryotes were able to grow more quickly than cells that did not possess mitochondria.

The endosymbiosis theory suggests that mitochondria may have evolved from bacteria that were takes inside other cells.

These cells then evolved into eukaryotes.

Give two structural features of mitochondria that support this theory

what would happen if each vesicle does not fuse with the plasma membrane

What would be the effect of DNP on the uptake of a substance in a cultured cell. (the rate of uptake is directly proportional to the concentration of the substance)
