Chemoreceptors called gustatory
<u>Answer</u>:
Neutral molecules are the products of the hydrolysis reaction.
<u>Explanation</u>:
Hydrolysis reactions are double decomposition reactions. In these reactions water reacts to the ester linkage in a molecule resulting into the breaking of bond between the elements of the molecules.
The products those result include the one which receives the hydroxyl (OH) group from the reacting water molecule and another one receives the remaining proton (H+). For example, if AB is a compound in which A and B are atoms or groups after the hydrolysis reaction with a water molecule (HOH) the products of this reaction may be the neutral molecules represented by the given reversible chemical equation i.e. AB + HOH ⇌ AH + BOH.
The location that should have lowest oxygen concentration would be the tissue because it is the furthermost location.
Other location with lowest oxygen concentration should be in the right part of the heart. It is when all unoxygenated blood pooled before going to the lungs. But the left part of the heart will have highest oxygenated blood, so it's ambiguous.
High oxygen concentration should be found in the environment, lungs, and the blood.
