If a postsynaptic neuron is stimulated to threshold by spatial summation this implies that . If a postsynaptic neuron is stimulated to threshold by spatial summation this implies that . the postsynaptic cell has a lower than normal threshold the postsynaptic cell has many synapses with many presynaptic neurons the postsynaptic cell is slow to repolarize the postsynaptic cell has many voltage gated ion channels

A postsynaptic neuron in a nerve cell procures the neurotransmitter after it has traversed the synapse and may confront an action potential when the neurotransmitter is strong.

The correct answer is:

Option B. The postsynaptic cell has many synapses with many presynaptic neurons.

This can be explained as:

Therefore, it implies that it has many presynaptic neurons.

The postsynaptic cell has many synapses with many presynaptic neurons

Explanation:

Spatial summation is a process of producing an action potential in a neuron with input from multiple presynaptic nerve cells. This process determines whether an action potential will be triggered upon reaching threshold from multiple synapses with presynaptic neurons. Summation of all inputs determines if an action potential will b generated.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
