Bacteria cell has chromosomal and plasmid dna and is prokaryotic (without a nucleus). Animal cell is eukaryotic (with a nucleus).
Bacteria cell has cell wall and cell membrane, but animal cell only has cell membrane.
Bacteria cell has no mitochondria, animal cell does.
Bacteria cell has flagella, animal cell doesn’t.
Prokaryotes: do not have a nucleus, use starch for energy, smaller ribosomes (70s)
eukaryotes: do have a nucleus, use glucose for energy, and have bigger ribosomes (80s)
Dopamine is a chemical that serves as a neurotransmitter that governs the transmission of signal between the neurons (brain cells) through binding to the receptors. This is also referred to "reward hormone" because this is excreted during activities that causes too much excitement or satisfaction.
The severe reduction in this hormone is linked primarily to disease that results from the dissociation of the breakdown of this hormone. This causes muscular paralysis, tremor, slow movement. Further this causes difficulty in movement initiation. This disease described above is the Parkinson's Disease.
