5 Μαΐ 2010 · Cellular respiration has three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis breaks down glucose into pyruvate and produces a small amount of ATP. The citric acid cycle further breaks down pyruvate and produces more ATP and electron carriers.

2 Pyruvate (3C) molecules are transported through the mitochondria membrane to the matrix and is converted to 2 Acetyl CoA (2C) molecules.
30 Ιουλ 2016 · These pathways take place in the cytoplasm and mitochondria and ultimately produce 36-38 ATP per glucose molecule through substrate-level phosphorylation and chemiosmotic phosphorylation. Cellular respiration and its production of ATP are essential for powering cellular work and processes.
17 Νοε 2014 · Pathways for Pyruvate • The pyruvate produced from glucose during glycolysis can be further metabolized in three possible ways • For aerobic organisms, when oxygen is plentiful the pyruvate is converted to acetyl coenzyme A (acetyl CoA) • For aerobic organisms, when oxygen is scarce, and for some anaerobic organisms, the pyruvate is ...
In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria (Figure \(\PageIndex{1}\)), which are the sites of cellular respiration. In order for pyruvate, the product of glycolysis, to enter the next pathway, it must undergo several changes.
How pyruvate from glycolysis is converted to acetyl CoA so it can enter the citric acid cycle. Pyruvate is modified by removal of a carboxyl group followed by oxidation, and then attached to Coenzyme A.
