Concept explainers
Interpretation: To determine the general description of the reaction that occurs in the first step of the citric acid cycle.
Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. This stage is included in the common
In the citric acid cycle, the acetyl unit produced in the second stage of the biochemical energy production process is oxidized. The final product of the citric acid cycle is CO2 and energy. Some part of the energy is lost as heat or some part is further carried by NADH or FADH2 in the fourth stage.
