What else can I help you with?
What was the effect of curare on eliciting an action potential?
It creates an action potential
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.
What mechanism does curare acts by?
Curare acts by blocking the transmission of nerve impulses at the neuromuscular junction, leading to muscle paralysis. It does this by binding to and blocking nicotinic acetylcholine receptors on the post-synaptic membrane, preventing the action potential from propagating across the muscle cell membrane.
What is the effect of curare on eliciting an action potential?
it is an alpha-toxin that binds to acetylcholine binding sites on the postsynaptic cell membrane, which prevents the acetylcholine from acting. Curare blocks synaptic transmission by preventing neural impulses to flow from neuron to neuron. It does allow the action potential to travel in the axon, it just doesn't pass it on to the dendrite.
Do neurotransmitters help to create new action potential?
No, neurotransmitters do not create new action potentials. They transmit signals between neurons by binding to receptors on the receiving neuron, causing a change in the membrane potential of the receiving neuron which may lead to the generation of a new action potential.
Where can you buy Curare?
Curare is a potent poison derived from various plants in South America. It is illegal to buy or sell Curare due to its toxic nature and potential for misuse as a weapon. It is mainly used for research purposes by qualified scientists and researchers in controlled laboratory settings.
What eats the plant curare?
No animal eats the plant curare. This is because the plant curare is toxic. The plant is poisonous and therefore is not consumed by animals.
Why may the curare-like drug affect respirations?
CURARE PARAlYSES MUSCELS
Why does tetrodotoxin effect your muscles?
It blocks the sodium channels that are required to create action potential in the muscles to make them contract.
Poem on topic utility of plants?
Plants are useful for many things. Some plants give us medicine. Other plants supply us with poison So that we can get rid of our teachers. Curare for example was developed By South American indigenous people From the foliage of the Calebas. Macusi Indians graded their Curare As One Tree Curare, Two Tree Curare ... and so on. To show how many trees a monkey could jump Before the Curare caused him to stop breathing. We would call our Curare One Lesson Curare, Two Lesson Curare .... and so on. Do teachers breathe?
How do animals use curare to survive?
Doctors use curare to help keep animals alive during surgeries. The curare helps to keep the animals respiratory systems going during surgery.
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
