The (matrix / stoma / cytoplasm / nucleolus) is the innermost compartment of a (cytoplasm / cell wall / mitochondrion / nucleus)
Olin [163]

Answer:

Matrix, Mitochondrion, Kreb's cycle, Pyruvic acid

Explanation:

The above question illustrates aerobic cellular respiration, specifically the second stage called Kreb's cycle or Citric acid cycle. This process occurs in the inner membrane of the mitochondrion of eukaryotic cells called MATRIX.

It occurs when the pyruvic acid produced during Glycolysis (first stage of cellular respiration that occurs in the cytoplasm) is converted to Acetyl CoA in order to enter the citric acid cycle in the mitochondrion. The Acetyl CoA is then used in a series of reactions that comprises of reduction-oxidation, hydration, dehydration, and decarboxylation.

This reactions involving 8 steps converts the Acetyl CoA (from pyruvic acid) to 2 molecules of CO2, 1 molecule of GTP/ATP, and electron donors NADH2 and FADH2.
