In the Mitochondria

The hexose sugar is broken down into pyruvic acid

The first step to respiration is glycolysis.
Glycolysis or "Splitting of sugar", has to happen in the cell's cytoplasm before cellular respiration can occur. I hope this helps!
The first step of the process is the digestion.

The third step in aerobic cellular respiration is the Krebs cycle.

The first step to respiration is glycolysis.
Cellular respiration occurs in three main steps. The first step takes place in the cytoplasm of the cell. The last two steps take place in the mitochondria(or if cellular respiration is taking place inside of a plant then the last two steps would take place in the chloroplasts) of the cell. Specifically, the second step occurs in the matrix of the mitochondria and the last step occurs along the inner membrane of the mitochondria, or the cristae.
Citric acid is formed during the citric acid (Krebs) cycle, which is the second stage of cellular respiration. In this cycle, acetyl-CoA is oxidized to produce ATP, CO2, and NADH in a series of reactions that take place in the mitochondria.
