GLYCOLYSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Glycolysis DOES NOT need ATP to occur.
A
True
B
False
Explanation: 

Detailed explanation-1: -Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.

Detailed explanation-2: -Energy is needed at the start of glycolysis to split the glucose molecule into two pyruvate molecules. These two molecules go on to stage II of cellular respiration. The energy to split glucose is provided by two molecules of ATP.

Detailed explanation-3: -Answer and Explanation: The statement that is not true regarding glycolysis is c. Glycolysis can occur in the cytoplasm of the cell or the mitochondria. Glycolysis only occurs in the cytosol or cytoplasm of the cells and not in the mitochondria.

Detailed explanation-4: -In organisms that perform cellular respiration, glycolysis is the first stage of this process. However, glycolysis doesn’t require oxygen, and many anaerobic organisms-organisms that do not use oxygen-also have this pathway.

Detailed explanation-5: -Solution : At the end of glycolysis, pyruvic acid molecules are obtained. <br> Glycolysis is the process of oxidation of a glucose molecule in a step wise manner to produce two molecules of pyruvic acid along with production of ATP, ‘NADH (2)‘ and water.
