Answer:
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.
inhalation: inhaling air (breathing in)
exhalation: exhaling air (breathing out)
D. Chemosynthetic bacteria do not need light
Answer:
The correct answer would be digestion and isomerization.
Starch is a polysaccharide formed by a number of glucose units.
The glucose units are attached with the help of glycosidic bonds.
In the digestion process, the polysaccharide is converted into simple glucose units with the help of different types of amylase enzymes such as alpha-amylase, glucoamylase.
In isomerization, some of the glucose units (40-50 percent) are isomerized to fructose with the help of glucose isomerase enzyme.
