What is an event when one or more presynaptic neurons fire in rapid order it produces a much greater depolarization of the postsynaptic membrane than would result from a single ESPS?
temporal summation
Movement of water molecules across the membrane is the result of?
osmosis
What would happen if the plasma membrane were composed solely of phospholipids and no proteins?
there would be no protein channels in the plasma membrane and as a result of that there would be no entry or exit of the materials across the membrane
Two changes in plasma membranes that could result in an increase in the rate of glucose?
To increase the absorption of glucose by a cell through plasma membrane two things can be done.One is treating cell membrane with chemicals that will distort the structure of cell membrane and then incubating the sample overnight at 37 degree Celsius.Another approach is giving electric shock to cell membrane.
What is the name of the cell that releases the neurotransmitters?
Exocytosis. As a result of the influx of Calcium ions, the synaptic vesicles transport the neurotransmitter Ach (Acetylcholine) to the presynaptic membrane, the vesicles fuse to the membrane, and the neurotransmiffer, Ach, diffuses. Once the neurotransmitters cross the synaptic cleft, they bind to the receptors on the post synaptic membrane. Hope it helps a bit.
Is anti alcohol drugs causes dystonia?
The drug acamprosate is one such substance that is used to treat alcohol dependence and can cause dystonia. It binds with GABA-A receptors, which is an inhibitory system, reducing neurotransmission and muscle contraction, and can result in dystonia.
What is an event when one or more presynaptic neurons fire in rapid order it produces a much greater depolarization of the postsynaptic membrane than would result from a single ESPS?
temporal summation
A postsynaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons?
true
Do clinically depressed person has too much GABA in the synaptic space?
There is no such things having too much or too little GABA in the synaptic space. The GABA is either positively or negatively charged. GABA acts at inhibitory synapses by binding to specific transmembrane receptors in the plasma membrane of both pre- and postsynaptic neuronal processes. This binding causes the opening of ion channels to allow the flow of either negatively charged chloride ions into the cell or positively charged potassium ions out of the cell. This action can result in a negative change in the transmembrane potential, usually causing hyperpolarization.
Is a postsynaptic potential a graded potential that is the result if a neurotransmitter released into the synapse between two neurons?
Yes it is true that graded potential can be called postsynaptic potentials. When a sensory neuron is excited by some form of energy, the resulting graded potential is called generator potential.
How can decision-making in the CNS result from the interaction between the activities of excitatory and inhibitory presynaptic neurons at synapses?
During decision-making, information is processed to choose between two or more alternatives. This involves the interaction of excitatory and inhibitory neurons. This process also involves excitatory and inhibitory neurotransmitters. The post-synaptic action potential is determined by the sum of all signals.
How does the end plate potential differ from a EPSP on a post synaptic cell?
End plate potential is the change in potential from neurotransmitters. It can be excitatory or inhibitory. If the action potential wants to continue, it will be excitatory and vice versa. It can be additive, if more action potentials are fired it will increase the end plate potential. An action potential is an all or none response. It will either proceed or it will not proceed depending on the terms of the threshold. It cannot be additive, because there is an absolute refractory period where no additional action potentials can be fired.
Movement of water molecules across the membrane is the result of?
osmosis
What is the result of damage to the thlaykoid membrane in a plant?
A decrease in glucose production
Is the flexible nature of a cell membrane result from its channel proteins?
Yes it is
How do nerve impulses cross the gap between nerve cells?
When an electrical signal, or impulse, reaches the end of an axon it triggers chemicals called transmitters. The electrical signals then become chemical ones as the transmitters cross the synapse, the gap between an axon and a dendrite. When they reach the dendrite of another neuron they spark a new electrical signal that then travels the length of that nerve cell. And it does this over and over until it reaches its destination.
What is one result of this complement fixation is which appears in the membrane of the foreign cell?
Lesions
