What are two types of receptors that help transmit signals across the cell membrane?
Ionotropic and metabotropic. Ionotropic is when the substance binds to the receptor, it causes the protein to change shape, opening thr channel for specific ions. Metabotropic is the second messenger model, where the substance binds, then activates certain enzymes and causes something to happen. E.g. Insulin might bind to receptors on the liver, activating an enzyme, causing glucose to be converted to glycogen (glycogenesis).

Neurons transmit signals acrossed a?
Neurons transmit signals across a small gap called a synapse by releasing neurotransmitters from the axon terminal. These neurotransmitters bind to receptors on the membrane of the receiving neuron, allowing the signal to continue along the neural pathway. This process is crucial for communication within the nervous system.
Which type of protein plays an important role in transmitting signals in the nervous system?
Neurotransmitter proteins play an important role in transmitting signals in the nervous system. These proteins are released from one neuron to another across a synapse, where they bind to receptors on the receiving neuron to transmit signals. Some examples of neurotransmitter proteins include dopamine, serotonin, and acetylcholine.
Where do neurotransmitters travel within the brain to transmit signals between neurons?
Neurotransmitters travel across synapses, which are small gaps between neurons, to transmit signals between neurons in the brain.
What role does neurotransmitters play in neurotransmission?
In between 2 neurones is the synaptic cleft, the gap between the pre and post-synapse. NTs are the molecules which activate receptors on the post-synapse during synaptic transmission, The activated receptors initiate intracellular mechanisms such as ion channel opening, G-protein activation, etc, which can inhibit or produce action potentials (nerve impulses).
How are receptors and transport proteins similar?
they are both components of the cell membrane

the nucleus.

The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.

What is the opening across which one neuron communicates with another neuron known as?
The opening across which one neuron communicates with another neuron is called a synapse. At the synapse, chemical signals called neurotransmitters are released from the presynaptic neuron, which then bind to receptors on the postsynaptic neuron to transmit the signal.
How are receptors and transport proteins similar?
they are both components of the cell membrane
Which part of the cell membrane helps chemical reactions happen?
The proteins embedded in the cell membrane, such as enzymes and receptors, facilitate chemical reactions by serving as catalysts or by binding to specific molecules to initiate signaling cascades. These proteins play a crucial role in regulating the transport of substances in and out of the cell and in transmitting signals across the membrane.
Two roles of membrane proteins?
Some membrane proteins are receptors for hormones or other chemicals. Some membrane proteins perform active transport of substances into or out of the cell.
Messages sent by relesing chemicals that jump across synapses involve in what?
Messages sent by releasing chemicals across synapses involve neurotransmitters, which are molecules that transmit signals between neurons. These neurotransmitters are released by the presynaptic neuron, travel across the synapse, and bind to receptors on the postsynaptic neuron to propagate the signal. This process is essential for communication within the nervous system.
The space between one neuron and the next is a?
This area is referred to as the synaptic cleft. This area is bound by the end of one neuron (the terminal bouton) and the post-synaptic membrane of the next neuron. When an action potential reaches the terminal bouton, Ca2+ influx triggers the release of neurotransmitters across the cleft, which bind to receptors on the post-synaptic membrane, allowing for an post-synaptic excitatory potential (PSEP) to be formed in the next neuron.
