GLYCOLYSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Justify that glycolysis evolved prior to the mitochondria.
A
Glycolysis takes place in the cytosol.
B
Glycolysis does not require a membrane which represents that it evolved prior to membrane bound organelles.
C
Glycolysis has instructions in the nuclear DNA.
D
Glycolysis does not require mitochondrial DNA which represents that it evolved prior to membrane bound organelles.
Explanation: 

Detailed explanation-1: -Glycolysis takes place in the cell cytosol, and not the mitochondrial membrane.

Detailed explanation-2: -Glycolysis does not occur in mitochondria because glycolysis is a process which requires lots of enzymes and organic molecules that are not in mitochondria and also mitochondria is an anabolic component so they work collectively for other mechanisms.

Detailed explanation-3: -No, glycolysis does not takes place in the mitochondria. It occurs in the cytosol.

Detailed explanation-4: -Glycolysis is the first pathway used in the breakdown of glucose to extract energy. Because it is used by nearly all organisms on earth, it must have evolved early in the history of life.
