Explanation:
The purple one that looks like an x
Answer:
The addition and response to the net effect of postsynaptic potentials is called Spatial summation
Explanation:
Signal summation occurs when impulses received by a neuron are eummed together to reach the excitation threshold to fire a neuron. It occurs at the axon hillock of a neuron. Signal summation occurs since each neuron is connected to many other neurons, often receiving multiple impulses from them, both excitatory and inhibitory.
Signal summation can either be temporal or spatial.
Temporal summation, occurs when impulses received at the same place on the neuron in close temporal succession add up to initiate an action potential in the neuron.
Spatial summation occurs when impulses received simultaneously at different places on the neuron add up to initiate an action potential in the neuron.
NADP
Photosystem 1 is a photochemical reaction
complex that uses energy from the light to produce high energy carriers NADPH
and ATP. Chlorophyll complex p700 have being identified as the photo-oxidation
reaction Centre in photosystem 1. However, NADP is known to be the final
electron acceptor in photosystem 1.
