Which one of the bonds is broken first in glycolysis to release energy?
Correct answer: A. Glycosidic
- A. Glycosidic
- B. Peptide
- C. Ester
- D. None
Explanation
Covalent bond formed between the 1st carbon atom of one monosaccharide with 4 carbon atoms of the neighboring monosaccharide unit is known as glycosidic bond which forms a polysaccharide. In the first step of glycolysis glucose is converted to glucose-6-phosphate with release of ATP(energy) with help of hexokinase enzyme. The bond broken is known as glycosidic bond.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
