    About the Lecture

    The lecture Signal Amplification & Dissemination by Thad Wilson, PhD is from the course Membrane Physiology.


    Included Quiz Questions

    1. High affinity
    2. High recognition
    3. High promiscuity
    4. High connectivity
    5. High association
    1. The receptor ‘recognizes’ the ligand’s specific conformation and specifically binds to it
    2. The ligand recognizes the receptor
    3. The cell recognizes the ligand
    4. The nucleus recognizes the ligand
    5. There is no specific conformational change in the receptor
    1. The bound receptor to the ligand causes a change in the receptor’s protein around it and starts a response
    2. The ligand changes its configuration
    3. The cell membrane changes its lipid configuration
    4. The ligand irreversibly binds to the receptor
    5. The ligand-receptor complex move into the cytosol
    1. Getting that transduced signal to the right target thus signaling a particular activation
    2. Transferring the signal from the ligand to the receptor
    3. The bound receptor to the ligand causes a change in the receptor’s protein around it and starts a response
    4. The cell recognizes the ligand
    5. Transducing the signal from the ligand to the receptor
    1. Interesting effects that alter the function of the cell
    2. Important changes in the ligand
    3. Irreversible changes in the receptor
    4. Permanent changes in the cell
    5. Permanent changes in the nucleus
    1. Remove the ligand or block the cascade of effects at same point
    2. Internalize the ligand-receptor complex
    3. Prevent removal of the ligand thus preventing further ligand-receptor contact
    4. Breakdown of the receptor
    5. Decrease the energy available to the receptor
    1. A muscarinic receptor
    2. A nicotinic receptor
    3. An adrenergic receptor
    4. A dopaminergic receptor
    5. A glutaminergic receptor
    1. G protein receptor
    2. Enzyme-linked receptor
    3. An ion-gated receptor
    4. A voltage receptor
    5. An ATP-gated receptor
    1. They transmit a signal to the potassium channel
    2. They directly affect the calcium channel
    3. They transmit a signal to the hydrogen channel
    4. They transmit a signal to the chloride channel
    5. They directly decrease influx of sodium into the cell
    1. They cause potassium to leave the cell
    2. They cause potassium to enter the cell
    3. They cause sodium to leave the cell
    4. They cause calcium to enter the cell
    5. They cause chloride to leave the cell
    1. Hyperpolarization
    2. Depolarization
    3. Prolongation of baseline voltage
    4. Tetany
    5. Relaxation
    1. Via the breaking down of Ach by local acetylcholinesterase
    2. Via discontinuation of delivery of Ach across the synaptic cleft
    3. Via re-uptake of Ach into the postsynaptic nerve
    4. Via the action of blood acetylcholinesterase
    5. Via removal of intact Ach from the receptor

    Great
    By Hongqian S. on 08. January 2018 for Signal Amplification & Dissemination

    It's more efficient than reading the book.Excellent, it's easy to understand!!!

     
    thank u
