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
 
        
             
        
        
        
Paneth cells are specialized immune cells that are found in the gastrointestinal tract. Paneth cells act as anti-microbial defence for our bodies. It is found in the crypts of the intestine.

Explanation:
Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.
