Question

Where is${\mathrm{CO}}_2$ produced in cellular respiration?

Answer 1

Krebs cycle:

1. It is also known as the tricarboxylic acid (TCA) cycle or citric acid cycle.
2. The cycle converts the available chemical energy of acetyl coenzyme A (acetyl CoA )into nicotinamide adenine dinucleotide's reducing power $\left(\mathrm{NADH}\right).$

Mitochondrial matrix:

1. ${\mathrm{CO}}_2$is created in the mitochondrial matrix during the TCA or Krebs cycle.
2. Ingested nutrients in the form of glucose $\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$ and oxygen are converted to energy in the form of adenosine triphosphate through cellular respiration (ATP).
3. As a result of this reaction, ${\mathrm{CO}}_2$ is created as a byproduct.
4. Inhalation provides the oxygen required for cellular respiration.
5. Hypercapnia or hypercarbia refers to the retention of${\mathrm{CO}}_2$.
6. Hypoventilation or a failure to remove excess${\mathrm{CO}}_2$ are common causes of hypercapnia, which can be detected with an arterial or venous blood gas.
7. ${\mathrm{CO}}_2$levels in the circulation can cause respiratory acidosis.
