Question: Noradrenaline neurotransmitters are released to a synaptic cleft between two neurons that is 90 nm wide. The diffusion coefficient for this neurotransmitter in the synaptic

Noradrenaline neurotransmitters are released to a synaptic cleft between two neurons that is 90 nm wide. The diffusion coefficient for this neurotransmitter in the synaptic cleft is 610cm/s. Within the synaptic cleft, initially there is no neurotransmitters present. When they are released from the pre-synaptic neuron, you find that the concentration of the Noradrenaline close to the pre-synaptic neuron is 0.002mM. Calculate the average flux of the neurotransmitters within the cleft, in mol/m-s with these initial concentrations. [Note: Watch out the units; 1mM=1mol/m ] J= Answel mol/m2s
