The binding of the neurotransmitter to receptors on the motor end plate causes which of the following to occur?

Biology
1 answer:

The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.

Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter ACh binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.

Lipids commonly contain fatty acids. What are the two parts of a fatty acid? Check the correct answers below.
ch4aika [34]

Answer:

Hydrophillic head and a hydrophobic tail

Explanation:

Every fatty acid is composed of long chain of hydrocarbon tail. This hydrocarbon tail is nonpolar and insoluble in water. Hence this tail is labeled 'hydrophobic'.

However, the head of the fatty acid contains polar COOH group which is capable of interacting with water, hence the head is hydrophillic.

Hence, a fatty acid is composed of a hydrophillic head and a hydrophobic tail.

2. Recombination.

Gamete mutations:
Gametic mutations are the mutations that occur in germline cells (sperm and egg). Due to this, the mutations are able to be passed on from one generation to another. One of the most famous gametic mutations<span> is hemophilia.

Recombination:
Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent.

snow_tiger [21]

Answer:

Cold temperature and higher pH cause the oxygen-hemoglobin saturation curve to shift high reflecting that hemoglobin releases more oxygen.

Explanation:

In higher pH i. e. neutral or alkaline and low body temperature, the hemoglobin molecule attach more oxygen to their active sites. When the temperature of the blood increases, the hemoglobin stops or reduces the binding of oxygen to their active sites and lower the saturation level.    Oxygen-hemoglobin saturation level refers to the amount of oxygen binds with the hemoglobin. This saturation decreases with increase in temperature and lower pH while saturation level increases when the temperature of the body is lower and pH is high.
