Answer:
D is the answer to this problem
Tertiary Amine
The reason Why it is Tertiary Amine is because it has three carbons and one nitrogen.
<span>an oxide of iron, magnesium, aluminum, and chromium</span>
Table salt = ionically bonded molecule, sodium transfers one valence electron to chloride, NaCl
Table sugar = covalently bonded molecule
Sorry, that’s all I know.
Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis. In geneal enzyme have a pHoptimum. However the optimum is not the same for each enzyme
