MUSCLE ENERGETICS GLYCOLYSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Glycolysis occurs predominantly in
A
cytosol
B
mitochondria
C
endoplasmic reticulim
D
nucleus
Explanation: 

Detailed explanation-1: -Glycolysis occurs in the cytosol of the cell cytoplasm because the glucose and other related enzymes required for the glycolytic pathway can be easily found there in high concentration. The cytoplasm may be a thick solution that fills each cell and is enclosed by the cell wall.

Detailed explanation-2: -Glycolysis is the partial oxidation of glucose to produce pyruvate, which is then transferred to mitochondria for further oxidation. The cytosol is the fluid in which the cell’s organelles are located. No, glycolysis does not takes place in the mitochondria. It occurs in the cytosol.

Detailed explanation-3: -Glycolysis occurs in the cytoplasm where one 6 carbon molecule of glucose is oxidized to generate two 3 carbon molecules of pyruvate. The fate of pyruvate depends on the presence or absence of mitochondria and oxygen in the cells.

Detailed explanation-4: -Glycolysis occurs in the cytoplasm and involves two stages which break up glucose – a 6-carbon molecule.

Detailed explanation-5: -Glycolysis takes place in the cell’s cytoplasm. Glycolysis is a process that happens in all living organisms, both aerobic and anaerobic.
