|
Carbon dioxide is produced
|
|
|
Lactic acid is produced
|
|
|
Glucose is oxidized into pyruvate
|
|
|
Glycolysis requires oxygen
|
Detailed explanation-1: -(iii) In the process of glycolysis, glucose molecules are oxidised to produce the molecules of pyruvate.
Detailed explanation-2: -Glycolysis Overview In most cells glycolysis converts glucose to pyruvate which is subsequently oxidized to carbon dioxide and water by mitochondrial enzymes. However, in some cells, most notably mature red blood cells, glycolysis is the only means of ATP production because of the lack of mitochondria.
Detailed explanation-3: -So, the correct option is ‘Glucose is partially oxidised’ and ‘It’s key product is triose sugar’.
Detailed explanation-4: -Which statement is true regarding pyruvate oxidation? Pyruvate oxidation forms the same number of NADH (per glucose molecule) as glycolysis.
Detailed explanation-5: -Answer and Explanation: In glycolysis, for each molecule of glucose oxidized to pyruvate, C. two molecules of ATP are used and four molecules of ATP are produced.
