Discussion

9095.	Question : Two neurons, A and B, synapse onto a third neuron, C.If neurotransmitter from A opens ligand-gated channels permeable to Na^+ and K^+ and neurotransmitter from B opens ligand-gated Cl^- channels, which of the following statements is true ?
Answer» An action potential in NEURON A causes a depolarisation in neuron B. An action potential in neuron B causes a depolarisation in neuron C. Simultaneous action potentials in A and B will cause hyperpolarisation of neuron C. Simultaneous action potentials in A and B will cause less depolarisation of neuron C than if only neuron A fired an action potential. Solution :Once neurotransmitters are released from the pre-synaptic axon terminal, they diffuse across the cleft.This results in binding of neurotransmitter to receptor and OPENING or closing of specific ion channels in the post-synaptic plasma membrane.Usually at an EXCITATORY snapse, channels in the post-synaptic cell that are permeable to `Na^+, K^+` and other small positive ions open, but `Na^+` flux dominates, because it has the largest electrochemical gradient.At inhibitory synapses, channels to `Cl^-` or `K^+` open.In the given SITUATION, the neuron B sends inhibitory pre-synaptic signals onto post-synaptic neuron C which would summate (subtract from ) with the AMPLITUDE of excitatory pre-synaptic signal caused by neuron A.Therefore depolarisation will be of lower amplitude.

Discussion

9099.	Question : Two key events take place during S phase in animal cells, DNA replication and duplication of centriole. In which parts of the cell these events occur ?
Answer» Solution : Replication of DNA takes PLACE in nucleus and DOUBLING of CENTRIOLE is seen in cytoplasm. Centriole forms spindle fibre during cell division in animal cell which controls chromosomal movement in a cell. The location of centriole determines location of nucleus and plays a key role in location RELATED arrangement of cell.
