quizket Yes, because if an EPSP is generated, then the cell was depolarized and the signal was sent to the brain. B. Yes, because if an EPSP is generated, then the match between the molecule and its receptor was appropriate and the signal was sent to the brain. C. No, because although each EPSP is sent to the brain, the brain doesn’t perceive the odor or taste unless an appropriate number of EPSPs are sent by the odor sensory cells. D. No, because enough of the appropriate molecules must bind to the receptors for a summed response from all the EPSPs to generate an action potential that is transmitted to the brain.

Complete Question

When an appropriate odor or taste molecule binds to its receptor, an excitatory postsynaptic potential (EPSP) is generated. Does this mean a signal goes directly to the brain and the odor or taste is perceived by the brain?

A. Yes, because if an EPSP is generated then the cell was depolarized and the signal was sent to the brain.

B. Yes, because if an EPSP is generated then the match between the molecule and its receptor was appropriate and the signal was sent to the brain.

C. No, because although each EPSP is sent to the brain, the brain doesn't perceive the odor or taste unless an appropriate number of EPSPs are sent by the taste or odor sensory cells.

D. No, because enough of the appropriate molecules must bind to the receptors for a summed response from all the EPSPs to generate an action potential that is transmitted to the brain

Answer:

D. No, because enough of the appropriate molecules must bind to the receptors for a summed response from all the EPSPs to generate an action potential that is transmitted to the brain.

Explanation:

Excitatory postsynaptic potential (EPSP) is an action potential that is generated by an excitatory postsynaptic cell.

Excitatory postsynaptic potential occurs when the Calcium ions channels are opened by chemicals known as neurotransmitters.

Excitatory postsynaptic potential causes the local depolarization of a cell membrane to occur which gives a graded response.

In order for an excitatory postsynaptic potential to create or cause an action potential to take place, the necessary or appropriate molecules must be joined to the receptors.

Answer:

Option- D

  • No, because enough of the appropriate molecules must bind to the receptors for a summed response from all the EPSPs to generate an action potential that is transmitted to the brain.  
  • There are certain neurotransmitters which are there for the transmission and collection of the appropriate level of information or data that is required for the regulation of the different functions inside the human body system.
  • While, the olfactory sense are comprised of such cells which consists of the different cells and the cells collects the different data along with sending the information towards the brain for regulation of these information in more specified way or sequence to form a valid results and provide a more response to that very change or any stimulus.
