What is the primary function of the electron transport chain?
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.
Does glycolysis use electron transport chain?
The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain. Clearly, the electron transport chain is vastly more efficient, but it can only be carried out in the presence of oxygen.
What is the primary role of the electron transport chain quizlet?
The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space sp that there will be a concentration gradient compared to the matrix of the mitochondria. This will drive ATP synthase.
What is the primary function of the electron transport chain quizlet?
The primary purpose of the electron transport chain is to harvest the energy from electrons moving down this pathway to produce ATP and water. The end-result of the electron transport chain is the formation of lactate.
What enters the electron transport chain?
All of the electrons that enter the transport chain come from NADH and FADH 2start subscript, 2, end subscript molecules produced during earlier stages of cellular respiration: glycolysis, pyruvate oxidation, and the citric acid cycle.
What molecules are required by the electron transport chain?
The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
What is the purpose of the electron transport chain in photosynthesis?
Electron transport helps establish a proton gradient that powers ATP production and also stores energy in the reduced coenzyme NADPH. This energy is used to power the Calvin Cycle to produce sugar and other carbohydrates.
What is the purpose of the electron transport chain in cellular respiration quizlet?
What is the function of the electron transport chain in cellular respiration? The electron transport chain shuttles electrons down a series of redox reactions that release energy used to make ATP.
What is the main function of the electron transport chain and oxidative phosphorylation processes quizlet?
Solution:The coenzymes NADH and FADH₂ are oxidized by the electron transport chain, and this oxidative process is coupled to phosphorylation of ADP to form ATP. Production of ATP is the main function of the overall process.
What is the purpose of embedding the electron transport chain in the membrane of a cell?
They are used to form water. What is the purpose of embedding the electron transport chain in the membrane of a cell? The membrane is impermeable to H+. Cellular respiration completely breaks down a glucose molecule through glycolysis and the citric acid cycle.
Which is more efficient glycolysis or electron transport chain?
The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain. Clearly, the electron transport chain is vastly more efficient, but it can only be carried out in the presence of oxygen.
How is the electron transport chain used in photosynthesis?
Photosynthesis is a metabolic process that converts light energy into chemical energy to build sugars. In the light-dependent reactions, light energy and water are used to make ATP, NADPH, and oxygen (O2). The proton gradient used to make the ATP forms via an electron transport chain.
Where do electrons go in the electron transport chain?
In the next phase of cellular respiration, the high-energy electrons within NADH and FADH2 will be passed to a set of membrane-bound enzymes in the mitochondrion, collectively referred to as the electron transport chain. These electrons will provide energy to do work.
How many ATP molecules are produced during glycolysis?
ATP Yield. In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.
