The oldest stage of cellular respiration is likely glycolysis. This metabolic process occurs in the cytoplasm of cells and breaks down glucose into pyruvate, generating a small amount of ATP and NADH. Glycolysis is considered ancient because it is found in nearly all living organisms, suggesting it evolved early in the history of life, before the advent of oxygen-rich environments. Its anaerobic nature indicates that it likely originated in a time when oxygen was scarce.
What else can I help you with?
What is the first stage of cellular respiration and the oldest in terms of evolution?
The first stage of cellular respiration is glycolysis, which occurs in the cytoplasm of cells. This process is thought to be the oldest stage of cellular respiration in evolutionary terms because it is a simple and ancient metabolic pathway that can occur without the presence of oxygen.
What is the first and oldest stage of cellular respiration?
Trapping Sunlight using enzymatically controlled processes, respiration needs free electrons to "respire".
What are the first stage of cellular respiration?
The first stage in cellular respiration is known as Glycolysis.
Which is not a stage of cellular respiration is it fermintaion or electron transport?
Fermentation is not considered a stage of cellular respiration as it does not require oxygen. On the other hand, electron transport is a crucial stage of cellular respiration that involves the transfer of electrons through a series of protein complexes in the inner mitochondrial membrane to generate ATP.
What is the only stage of cellular respiration that occurs in the cytoplasm?
Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. No oxygen is needed for this stage of respiration and it occurs in cells that respire using mitochondria and cells that ferment sugars.

What is the importance of cellular respiration?
your skin is the most important stage of cellular respiration
What is the stage of cellular respiration?
it not fermentation
Where in the cell does the second stage of respiration?
The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.
What is the first stage of the cellular respiration?
Glycolysis!
What stage in cellular respiration is anaerobic?
glycolysis
Is kerbs cycle part of cellular respiration?
Ya, it is the second stage in respiration.
First stage in cellular respiration?
glucose (:~Alyssa
What happens in the first stage of cellular respiration?
Hippies ;)
