Answer:
1. Acetylcholine binds to receptors on the motor end plate
2. Ligand-gated channels open leading to depolarization
3. End plate potential triggers an action potential
4. Transverse tubules convey action potentials into the interior of the muscle fiber
5. Calcium is released from the sarcoplasmic reticulum
6. Calcium ions bind to troponin, which then moves tropomyosin
Explanation:
Acetylcholine (ACh) is a signaling molecule (neurotransmitter) that binds to receptors on muscle cells. This binding triggers the opening of ligand-gated sodium channels, thereby ions enter into muscle cells, which causes the depolarization of the sarcolemma and thus promotes the release of Ca2+ ions from the sarcoplasmic reticulum. The myoneural junction, also known as the motor endplate, is the site of synaptic contact between a motor axon and a skeletal muscle fiber. The endplate potential is the voltage that produces the depolarization of muscle fibers when ACh molecules bind to their receptors in the cell membrane. This depolarization spreads in the sarcolemma through transverse tubules (T tubules) and thus generates an action potential. Finally, this action potential induces the release of Ca2+ in the sarcoplasmic reticulum, which activates troponin protein and induces muscle contraction.
Answer:
Hello There!!
Explanation:
The purpose of the chloroplast is to make sugars that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose. When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy.
hope this helps,have a great day!!

Ammonia (NH3) is inorganic and would be the answer to your question
Answer:
increasing thirst when cells are low on water
Explanation:
<span>THC is stored in fat. That being said, even if you are a skinny person there are other factors that could affect how the test would turn out. It depends on how much water you drink, what kind of test you take for the weed and how much weed you smoke. There is no set answer. It could be a week or 10 days if you aren't a steady user of pot.</span>
