Question

What does pyruvate do in cellular respiration?

Answer 1

Cellular respiration:

1. Cellular respiration is the process whereby cells use the food consumed to produce usable energy in the form of ATP.
2. Adenosine triphosphate, or ATP, is high-energy molecule cells use as their energy source.

The role that pyruvate do in cellular respiration is:

1. Cellular respiration is a three-phase procedure.
2. The phases are known as glycolysis, the Krebs cycle, and the electron transport chain.
3. Within these phases, it is an important molecule called pyruvate, sometimes referred to as pyruvic acid.
4. Pyruvate Do in Cellular Respiration
5. Pyruvate is made in the cytosol by glycolysis.
6. Pyruvate enters the mitochondrion by traveling through a channel in the outer membrane and then through a $H^{+}/$pyruvate symporter in the inner membrane.
7. Pyruvate is then oxidized via pyruvate dehydrogenase to an acetyl group and $C{O}_2$.
8. $NADH$ is also synthesized as an end product.
9. During this process, the acetyl group is transferred to coenzyme A and later it will be removed and enter the citric acid cycle.
