How many ATP molecules will be synthesized in eukaryotic cells upon complete oxidation of a starch molecule fragment consisting of 70 glucose residues?
1) Starch under the action of hydrolytic enzymes is cleaved in the lysosome to less complex organic substances (monomers) – glucose. In this case, 70 molecules are formed;
2) With the complete oxidation of one glucose molecule (in mitochondria) 38 ATP molecules are synthesized;
3) When 70 glucose molecules are oxidized,
70 x 38 = 2660 ATP molecules
Answer: 2660 ATP molecules
