The citric cycle
網頁Among the four stages of cellular respiration, pyruvate oxidation is kind of the odd one out; it’s relatively short in comparison to the extensive pathways of glycolysis or the citric acid cycle. But that doesn’t make it unimportant! On the contrary, pyruvate oxidation is a key connector that links glycolysis to the rest of cellular respiration.

Did you know?
網頁2024年3月25日 · The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid (TCA) cycle, is a series of biochemical reactions that occur in the mitochondria of eukaryotic cells and the cytosol of prokaryotic cells. The cycle plays a crucial role in the cellular respiration process, which generates energy in the form of ATP. 網頁Unlike glycolysis, the citric acid cycle is a closed loop: The last part of the pathway regenerates the compound used in the first step. The eight steps of the cycle are a series …
網頁2024年12月5日 · The eight steps of the citric acid cycle are a series of redox, dehydration, hydration, and decarboxylation reactions. Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell. Key Terms 網頁Citric acid cycle Entry into the citric acid cycle is largely controlled through pyruvate dehydrogenase (above), the enzyme that produces acetyl CoA. However, there are two …
網頁The reverse Krebs cycle (also known as the reverse tricarboxylic acid cycle, the reverse TCA cycle, or the reverse citric acid cycle, or the reductive tricarboxylic acid cycle, or the reductive TCA cycle) is a sequence of chemical reactions that are used by some bacteria to produce carbon compounds from carbon dioxide and water by the use of … 網頁2024年10月1日 · The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle, is a circular loop rotating through eight organic acid intermediates (e.g., citrate, malate, oxaloacetate). The intermediate products formed in this cycle (see figure 1) are used to build molecules including proteins, DNA, and RNA.
