Document Summary
Evidence: morphology, reproduction (a mito can only come from a mito like in living cells, genetic information (have their own, circular dna, linear dna in nucleus, transcription and translation performed by same ribosomes, electron transport etc found in inside membrane, since they both have a double membrane, sequence analysis sequencing of rna reveals similarities to ancestors to possible descendants, horizontal gene transfer different compartments at first, but then some genes disappeared, might not yet be complete or might need to be separate for optimal functioning because they were redundant, some were relocated to different areas in the cell (hgt) Enzymatic proteins: membrane transport proteins (ion transporters na+ and k+, motile proteins produce cellular movements (ie. myosin acts on microfilaments to produce, regulatory proteins (promote or inhibit the activity of other cellular molecules, receptor proteins (bind molecule at cell surface to trigger cell response ie hormone receptors, hormones carry messages, antibodies defend against invading organisms, venoms and toxins.
