BIOL 213 1st Edition Lecture 22 Outline of Last Lecture I Cytoskeleton II Intermediate filaments a Structure b Main functions c Two main different kinds i Cytoplasmic and nuclear lamins III Microtubules a Structure i Made of tubulin b Formed from centrosomes c Dynamic instability d Intracellular transport i Motor proteins dynein and kenisin e Mitosis IV Actin filaments a Structure b Growth occurs at both ends c Interaction with myosin to cause muscle contraction These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute Outline of Current Lecture I Signal transduction a 5 different kinds of signaling II Response to signaling III Intracellular receptors a Ex nitric oxide and steroid hormones IV Cell surface receptors a 3 main kinds i Ion channels G protein coupled receptors enzyme linked receptors b Molecular switches Current Lecture I Signal transduction a This is the process of converting one form of signal into another b Signal molecules i These can be a lot of different things proteins peptides amino acids steroid hormones fatty acids sugars inorganic compounds gases c Different molecules can mimic or inhibit the signal i Agonist 1 Activates the pathway 2 They mimic the signal ii Antagonist 1 Blocks the pathway 2 They inhibit the signal d These signal molecules bind to receptor proteins to trigger a response e 5 different kinds of signaling i Endocrine 1 The signals travel through the blood all over the body ii Paracrine 1 These signals are released by one cell or a small group of cells and only affect the cells within the immediate vicinity iii Neuronal 1 Neurotransmitters are released by a neuron 2 The target cell is usually a muscle cell or another neuron iv Contact 1 The signal never leaves the signaling cell 2 It s on the surface of the signaling cell and the target cell has to be in direct contact with the signaling cell to get the message 3 The target cell
