Which of the following pathways for the transformation of cellular energy most likely evolved first?
Coenzyme that transfers electrons from the Krebs Cycle to the mitochondrial electron transport chain at a lower energy level than that of electrons entering at the beginning of the chain.


Sagot :

The first phase of both aerobic and anaerobic respiration is known as glycolysis. Therefore, it is most likely that this method for converting cellular energy came into being first.

What are the three basic mechanisms through which cells produce energy?

Glycolysis, the citric acid cycle, and the electron transport chain are three distinct metabolic pathways that work together to form cellular respiration. While the other two mechanisms are aerobic, glycolysis is anaerobic.

Which came first, oxygen or photosynthesis?

The process of photosynthesis is what allows for sophisticated life to exist on Earth. Photosynthesis is also the source of all oxygen on our planet. Both oxygenic and anoxygenic photosynthesis is possible. Oxygenic photosynthesis splits water molecules with the help of light energy, releasing oxygen, electrons, and protons.
