5 Questions
Explain the direction of movement for the motor protein Kinesin and the associated end of the microtubule it moves towards?
Kinesin 'walks' towards the plus end of the microtubule.
What will be the result if the Ca2+ influx in the axon terminal was significantly reduced?
Less neurotransmitters will be released as a result of less vesicle fusion from reduced calcium levels.
Which statement about neuropeptides is false?
The false statement is: 'Release into the synaptic cleft requires an influx of Ca2'.
What is the primary effect of benzodiazepines as an agonist of the neurotransmitter GABA when applied to a neuron-neuron synapse?
Increased amplitude of EPSPs in the post-synaptic neuron.
What is the direction of movement for the motor protein Dynein and the associated end of the microtubule it moves towards?
Dynein 'walks' towards the minus end of the microtubule.
Test your knowledge of motor proteins and their functions with these study questions from the class. This quiz covers the movement of kinesin and dynein along microtubules, as well as the impact of reduced Ca2+ influx on neurotransmitter release at axon terminals.
