Adrenergic modifiers bind to epinephrine receptors while
cholinergic modifiers bind to ACh receptors. Either of these drugs will inhibit
the natural ligand actions or mimic the natural ligand molecules when it binds to the
receptor.
Epinepherine can be classified as adrenergic, even though it is a
natural ligand (chemical). Pilocarpine is a good example of a cholinergic
chemical.
<h2>Intercostal Muscle</h2>
Explanation:
Very young children tend to breathe predominantly with their diaphragm because:
c. their intercostal muscles are not fully developed.
Intercostal muscle are located between the ribs and helps in the movement with of the chest. These help in increasing the volume of the chest and are mainly associated with the breathing. Young childrens do not have very well developed intercostal muscle and so they use their diaphragm to breathe.
From the coronary arteries, which originates from the aorta<span />
Answer:
3.Cell respiration produces sugar for energy storage.
Explanation:
The process of cellular respiration does not produce sugars. This is a catabolic pathway that breakdown nutrients such as sugars. In the presence of oxygen, sugars are completely oxidized into CO2 and H2O. The energy stored in the chemical bonds of sugars is used to make ATP. The process occurs in three steps: glycolysis, citric acid cycle and electron transport chain. ATP is the energy currency of the cells. Therefore, cellular respiration produces ATP, not sugars.
