BIO 181

Lecture notes from Ebie Modules 1-5

1 BIO 181 EXAM 3 STUDY GUIDE: 1. Receptors are made from membrane-bound polyribosomes. 2. Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action potential in the postsynaptic cell. 3. The axon from a pre-synaptic cell contacts the axon of another neuron. 4. In the motor end plate, the event that is the immediate trigger for exocytosis is: Calcium Ions 5. The receptors in post-synaptic cells are the basis on which the synapse can be ...

T or F: Potassium ions are at high concentrations inside of cells, including neurons correct answer: True The action potential is a result of: correct answer: the movement of ions The post-synaptic cell can be: correct answer: in glands, muscle cells and neurons Th resting potential of a neuron is correct answer: -60mV T or F: The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal correct answer: false T or F: Voltage gated...

The association of ribosomes with _____ invaginations would support the _____ theory. correct answer: membrane, endomembrane After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is? correct answer: filapodia, lamellipodia, cell muscle, retraction fiber T/F It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells. correct answer: true T/F In an extant prok...
