WebKrebs cycle. (krĕbz) n. A series of enzymatic reactions in aerobic organisms involving oxidative metabolism of acetyl units and producing high-energy phosphate compounds such as ATP, which serve as the main source of cellular energy. Also called citric acid cycle, tricarboxylic acid cycle. WebThe pathways for all three macronutrients are illustrated in Figure 1-2, but before discussing each, let’s first define the fuels: Triglycerides (TG) ... Let’s start by looking at the Krebs cycle – it is the point where all 3 macronutrients converge in the mitochondria. Think of the Krebs cycle as a bar or night club, a location where ...
