Small, but normal variations in genes may produce proteins that work differently from those of other individuals ( friends or relatives). This may affect how we respond to different medicines. The extent to which these proteins functions varies from one individual to another. Example; certain painkillers only work when body proteins convert them from an inactive form to an active one. If these proteins work too fast, the drug will be eliminated from the body before it has time to work. To do their job the pain killers need to bind and modulate a target body protein, the receptor, such that if the target body protein is altered the pain killer might not be able to bind.
Answer:
Following statements are correct
A graded potential has a threshold Graded potential amplitudes decay over distances
Graded potentials can summate in space and time
Graded potential amplitude increases with stimulus strength
Explanation:
Graded potential is generated in a neuron when ions enter or exit through the ligand gated channels. In general, this potential decreases with time before reaching axon. Signals that reach the graded potential, determine whether the amplitude of the potential will reach the threshold and hence causes action potential. Graded potential travel only over a short distance and is either depolarization or hyperpolarization. Their strength reduces with time as the charged ions move out of the membrane. They summate temporally or spatially
Graded potentials spread by passive means i.e spreading electronically to neighboring membrane regions.
Hence, the correct statements are
A graded potential has a threshold Graded potential amplitudes decay over distances
Graded potentials can summate in space and time
Graded potential amplitude increases with stimulus strength
