What protein classes are not found as membrane proteins - identity markers or receptors or transport channels or enzymes or hormones?
Hormones are not found as membrane proteins.
What is the role of ATP in sodium-potassium pump?
transport across the membrane
Can Iodine Potassium Iodine when mixed with a starch diffuse through a semipermeable membrane?
yes
In fact polar molecules are unable to go across unless?
they pass through channels in the cell membrane
What type of channel does sodium and potassium use to diffuse across the plasma membrane of all cells?
voltage type of channel
What is ACh receptors?
ACH receptors can be defined as an integral membrane protein that responds to the binding of acetylcholine, a neuoyansmitter. Two example are nicotinic acetyl line receptors and muscarinic acetylcholine receptors. .
Are channels carriers and receptors associated with mitosis?
Channels, carrriers and receptors are proteins associated with with the cell membrane.
What happens to the muscle membrane when acetylcholine binds to receptors at the motor plate?
When acetylcholine binds to receptors at the motor plate, this binding opens ligand-gated ion channels on the motor end plate, ions diffuse through the open ligand gated ion channels, and the flow of ions causes the motor end plate to reach threshold and an action potential is generated at the motor end plate.
What neurotransmitter control the somatic nervous system and how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.
What neurotransmitter controls the somatic nervous system how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.
At the neuromuscular junction, the muscle contraction initiation event is?
binding of acetylcholine to membrane receptors on the sarcolemma
What does the synaptic knobs of the presynaptic neuron contain synaptic vesicles loaded with?
To provide energy for the re-combination of Choline and ethanoic acid, to form Acetylcholine. Acetylcholine is used as a neurotransmitter, and gets broken down after its reached the sodium channels' receptors on the post-synaptic membrane by acetylcholinease.
What passive channels are likely found in the pacinian membrane?
The efflux of potassium ions is maintained by passive potassium channels.
What part of the muscle cell membrane contain acetylcholine receptors?
When the Ach binds to receptor sites on the muscle cell membrane it causes channels to open and allows Na+ to move into the cell which then causes an action potential.
What functions do proteins have in the cell membrane?
Receptors, Selective Channels and pores
Are Proteins in the cell membrane may serve as channels receptors or markers?
both
What happens to your acetylcholine when you stumble?
from answers.com When a nerve impulse reaches an axon ending, voltage-gated calcium channels in the axonal membrane open and calcium, which is extremely low inside the cell, enters the nerve ending. The increase in calcium-ion concentration causes hundreds of synaptic vesicles to fuse with the cell membrane and expel acetylcholine into the synaptic cleft (exocytosis). The acetylcholine released at a neuromuscular junction binds reversibly to acetylcholine receptors in the muscle end-plate membrane, a postsynaptic membrane that is separated from the nerve ending by a very short distance. The receptor is a cation channel which opens when two acetylcholine molecules are bound, allowing a sodium current to enter the muscle cell and depolarize the membrane. The resulting impulse indirectly causes the muscle to contract.
