Answer: The action of a neurotransmitter at the postsynaptic cell is terminated by the following: enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
Explanation: After a neurotransmitter has bound to its receptor on the postsynaptic membrane and triggered a biological response, in order to avoid over stimulation of the receptors, the neurotransmitter is either degraded by specific enzymes or taken back to the presynaptic cell into the synaptic vesicles by action of specific transporters. This mechanism is to maintain a balance (homeostasis).
<h2>Pericardium </h2>
Explanation:
Pericardium is the fibrous tissue that surrounds the heart and the roots of the great blood vessels
The pericardium's outer coat is called the parietal pericardium which is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the breastbone
Its inner coat is called the visceral pericardium or epicardium which is double, with one layer closely adherent to the heart and the other lining the inner surface of the outer coat
The intervening space between these layers is filled with pericardial fluid
This small amount of fluid acts as a lubricant to allow normal heart movement within the chest
The cells of diplomonads and parabasalids have modified mitochondria.
Diplomondas are small zooflagellates that inhabit the digestive systems of various animals, including termites, rats, and humans. Diplomonads do not posses true mitochondria, and thus they cannot perform respiration and instead must obtain their energy from fermentative processes. Parabasalids on the other hand also lack true mitochondria and instead contain small hydrogenosomes which apparently developed from reduced mitochondria.
Answer:
AIt removes H2O from the atmosphere during glycolysis.
Explanation: It removes H2O from the atmosphere during acetyl CoA formation. Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not. Thats so easy :D
Glycolysis
this catabolizes glucose into pyruvate
