How will you calculate net products of one sucrose molecule upon complete oxidation during aerobic respiration as per recent view ?

Explanation

Net products gained during aerobic respiration per glucose molecule.


1. Complete oxidation of a glucose molecule in aerobic respiration results in the net gain of 36 ATP molecules in plants as shown in the table.
2. However in animal tissue where malate shuttle mechanism is present , oxidation of external NADH will yield almost three ATP molecules.
3. Since huge amount of energy is generated in mitochondria in the form of ATP molecules they are called 'power house of the cell'.
4. In the case of aerobic prokaryotes due to lack of mitochondria each molecule of glucose produces 38 ATP molecules.
Recent view :
1. When the cost of transport of ATPs from matrix into the cytosol is considered, the number will be 2.5 ATPs for each NADH `+H^+` and 1.5 ATPs fro each `FADH_2` oxidised during electron transport system.
2. Therefore , in plant cells net yield of 30 ATP molecules for complete aerobic oxidation of one molecule of glucose.
3. Sucrose is made up of a molecule of glucose and a molecule of produces (monosaccharides). Glucose and fructose are isomers.
4. The fructose unit to sucrose will be converted into glucose in liver and adipose tissue.
5. Hence if one glucose molecule yields 30 ATP on complete oxidation (Recent view), net products of one sucrose molecule upon complete oxidation during aerobic respiration =60 ATP.
