Question

Where in the cell does the krebs cycle part of cellular respiration occur ?

Answer 1

Answer:

In the mitochondrial matrix

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.
