<span>When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure inside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the <span>lungs. hope this helps</span></span>

Where in the cell does the krebs cycle part of cellular respiration occur ?
neonofarm [45]

Answer:

<u>In the mitochondrial matrix</u>

<u></u>

Explanation:

The mitochondria is an organelle within the cytoplasm of the cell.  It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into CO_{2} (carbon dioxide) and  H_{2} O (water) to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:

C6H12O6+ 6 O2        →      6 CO2 + 6 H2O + ≅38 ATP

(glucose)   (oxygen)         (carbon dioxide) + (water)

The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.
