Answer and Explanation: The main function of the Krebs cycle is to produce electron carriers that can be used in the last step of cellular respiration.
The main function of the Krebs cycle is to transfer high energy electrons to the electron transport chain using the carriers used in Krebs cycle.
what occurs during the Krebs cycle? The Krebs cycle occurs in the mitochondrial matrix and generates a pool of chemical energy (ATP, NADH, and FADH2) from the oxidation of pyruvate, the end product of glycolysis. Pyruvate is transported into the mitochondria and loses carbon dioxide to form acetyl-CoA, a 2-carbon molecule.
Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
The function of the electron transport chain is to produce a transmembrane proton electrochemical gradient as a result of the redox reactions. If protons flow back through the membrane, they enable mechanical work, such as rotating bacterial flagella.
Below is a list of answers to questions that have a similarity, or relationship to, the answers on "What is the main function of the Krebs cycle?". This list is displayed so that you can easily and quickly access the available answers, without having to search first.
The basic function of fermentation is the production of ethyl alcohol or lactic acid. The basic function of fermentation is the regeneration of NAD+, which allows continued ATP production by glycolysis. Fermentation occurs in the absence of oxygen and does not yeild as much ATP.
Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2. These carriers then donate electrons and protons to the electron carrier proteins of the electron transport chain. The final electron acceptor is oxygen. Together with oxygen, electrons and protons form molecules of water.
The Purpose Cellular Respiration Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.
C 6 H 12 O 6 + 6 O 2 -- > 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.
