Krebs Cycle

Also known as the citric acid cycle, the Krebs cycle occurs inside the mitochondria of cells. It is a multi-step process that follows glycolysis. In the Krebs cycle, 2 pyruvic acid molecules produced through glycolysis yield 10 NADH, 2 FADH, and 2 ATP molecules. The ATP supplies energy, and the NADH and FADH are used in the following process, the electron transport chain. As well as producing NADH, FADH, and ATP, the Krebs cycle releasing carbon dioxide as waste. The 6 molecules of carbon dioxide released represent the 6 carbons of glucose that entered the cycle through glycolysis. Just as animals and other organisms, the plant uses the Krebs cycle to produce ATP and other molecules in order to partake in cellular respiration.
