When a neurotransmitter reaches an excitatory synapse

Biology
1 answer:
grigory [225]3 years ago
5 0

Answer:

Sodium ions move into the postsynaptic neuron causing depolarization of the

postsynaptic neuron

Explanation:

That's the mechanism of action potential generation. Neurotransmitter receptors are connected to sodium channels. When those sodium channels open the cell becomes depolarized(the charges reverse), that means the inside of the cell becomes more positive while the outside becomes negative

Archy [21]

Answer:

metabolism

Explanation:

Metabolism is a chemical reaction that involves break down of compounds to simple molecules that provide energy or synthesis of compounds. Metabolism can be classified into two; catabolism and anabolism.

Catabolism is the break down of componds through a cascade of events to provide energy in form of ATP, NADP. Anabolism is the the synthesis of compounds using energy released during catabolism to form complex structures. An example of catabolism is glycolysis and anabolism is the formation of proteins etc.

A 1.0-kb DNA fragment from the 5' end of the mouse gene is examined by DNA footprint protection analysis. Two samples are end-la
vampirchik [111]

Answer:

Explanation:

Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.

As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.

Answer:

Radiometric dating methods

Explanation:

Geologists usually use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon to find the age of fossils.
