2 mar 2014 · The tricarboxylic acid (TCA) cycle is a series of enzyme-catalyzed reactions that forms a key part of aerobic respiration in cells. It was discovered by Hans Krebs in 1937 and is also known as the Krebs cycle or citric acid cycle.

photosynthesis creates glucose molecules (instead of eating) → 2) this fuels cellular respiration in the plant cells → 3) creates ATP → 4) fuels plant growth and reproduction → 5) provides carbohydrates to animals for their cellular respiration. The cycle continues. The formula in plants is:
The major process of ATP production is carbohydrate metabolism within cells. This is done via two main pathways: glycolysis and the citric acid cycle (Kreb’s or tricarboxylic acid cycle). Glycolysis is the breakdown of glucose to form pyruvate. At some stages ATP is generated directly, at other stages a proton (H+ ion) is passed to the coenzymes:
ATP – ADP CYCLE. ¡ To supply cells with energy, a “high energy” bond in ATP is broken. ADP is formed and a phosphate is released back into the cytoplasm. ATP à ADP + phosphate + energy.
Electron-Transport Chain and ATP production. Occurs in the inner mitochondrial membrane where NADH and FADH2 are oxidized back to NAD+ and FAD. They transfer their e- in a series of steps and ultimately to O2: O2 + 4e- + 4H+ ® 2H2O.
