Chemical A, because if the cytoplasm is flooded with calcium, then the actin and myosin would slide into eachother, causing the muscle to contract.
In the cytoplasm, because that is where the chemical reactions happen.
in the cytosal
Chemoreceptors (chemical receptors) respond to chemicals in food and scents.
Is where the chemical changes of the cell happen
mitochondria
The neurotransmitter acetylcholine is released into the synaptic cleft to bind with receptors on muscle cells. Upon binding, the muscle cells contract.
acetylcholine (ACh)
Acetylcholine
Muscle contractions would be prevented, causing paralysis.
Parasympathetic system has acetylcholine as its chemical mediator.
Chemical Receptors
The chemical formula (not symbol) of acethylcoline is CH3COO(CH2)2N+(CH3)3.
acetylcholine
acetylcholine
chemical receptors
Neurotransmitters diffuse across the synaptic cleft to bind to membrane receptors on the next neuron. This initiates a synaptic potential.
