BIO 1140 Lecture Notes - Lecture 5: So Small, Blackboard, Plant Cell
Document Summary
Cell size and scale: differences, shape, they have similar and different features. There are a whole bunch of very important characteristics that we cannot see: aka "dna". Neurotransmitters that come from the brain, go to the brain from the heart by neurones, with gap junctions which is called synaptic transmission. Little tunnels between one sell to another exchanging ions, called gap junctions made up on connexion: this is the same of all types of tissues, they all fall under the umbrella of signal transduction. The tree of life: compare prokaryotes to eukaryotes throughout this course general, but then soon in to what exactly is going on with in the cell specifically. Ribosomal is the answer: ribosomes are important for protein translation, each organism in the tree of life is made up of different proteins, archea are much closer to eukaryotes then they are to bacteria.
