A. another hydrogen ,a gas
B. A carbon , carbon dioxide
C. An oxygen , water
D. a pyruvic acid, lactic acid

​

Answer 1

an oxygen,water.............,...............

Answer 2

The answer is option C. An oxygen, water

Explanation:

• Glycolysis is defined as the process of partial oxidation of glucose to form two molecules of pyruvic acid.
• During aerobic respiration- when oxygen is available a water molecule is formed through electron transport of mitochondria. In this process, a half molecule of oxygen is utilized for the synthesis of each water molecule.
• This takes place when 2-phosphoglycerate is convert into phosphoenolpyruvate in the presence of enolase.

Please refer to the image attached for the glycolysis pathway.
