All organisms carry out the Krebscycle in mitochondria.

|
|
Glycolysisis a universal energy-releasing process and is present in a common ancestor forall forms of life.
|
|
|
Across the three domains, allorganisms are made up of cells.

|
|
The presence of glycolysis as anenergy-releasing process in all organisms suggests that convergent evolutionoccurred.

Detailed explanation-1: -It takes place in the cytoplasm of all living cells irrespective of the cell type i.e., it can occur in both prokaryotic and eukaryotic cells.
Detailed explanation-2: -Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.
Detailed explanation-3: -Glycolysis occurs in the cytoplasm of nearly every cell. Organisms, from the small, circular colonies of bacteria pictured here to the human holding the petri dish, perform glycolysis using the same ten enzymes. Because of this, it is thought that glycolysis must have evolved in the very earliest forms of life.
Detailed explanation-4: -Glycolysis is the first pathway used in the breakdown of glucose to extract energy. It takes place in the cytoplasm of both prokaryotic and eukaryotic cells. It was probably one of the earliest metabolic pathways to evolve since it is used by nearly all of the organisms on earth.
