substrate level phosphorylation
Glycolysis is a metabolic process in eukaryotic cells that can proceed normally in the absence of oxygen. It converts glucose into pyruvate, producing ATP as an energy source for the cell.
The defining characteristic of prokaryotic cells that sets them apart from eukaryotic cells is the absence of a distinct nucleus.
Prokaryotic cells can be aerobic (requiring oxygen) or anaerobic (not requiring oxygen), while eukaryotic cells typically require oxygen for aerobic respiration. However, some eukaryotic cells can also perform anaerobic respiration in the absence of oxygen.

Oxygen is the gas used by eukaryotic cells for cellular respiration. Oxygen is required for the process of oxidative phosphorylation, which is the final stage of cellular respiration where ATP is produced.
Eukaryotic cells require oxygen for cellular respiration, a process that occurs in the mitochondria to produce ATP, the energy currency of the cell. Oxygen acts as the final electron acceptor in the electron transport chain, allowing for efficient energy production. Without oxygen, eukaryotic cells would rely on less efficient anaerobic processes for energy, leading to reduced ATP yields.
In the absence of oxygen after glycolysis, muscle cells will produce lactic acid through the process of fermentation. This allows the cells to regenerate NAD+ needed for glycolysis to continue in the absence of oxygen.
fermentation occurs in the absence of oxygen (anaerobic respiration). in muscle cells, when the blood supply is inadequate, anaerobic respiration takes place and the glucose is converted into lactic acid in the absence of oxygen :)
The Oxygen molecule determines if the Pyruvic acid enters Krebs cycle or undergoes fermentation. If Oxygen is present, it enters the Krebs cycle, whereas in its absence, it undergoes fermentation.
In prokaryotic cells, DNA and RNA are both found in the cytoplasm. In eukaryotic cells, DNA is typically restricted to the nucleus and RNA is mostly in the cytoplasm.
