The high energy from the electron carriers NADH and FADH2 is passed to membrane-bound enzymes that use the energy to pump protons across the inner membrane into the inter-membrane space. The energy is gradually used by an entire "chain" of enzymes to establish a proton gradient across the inner membrane of the mitochondrion.
This is where chemiosmosis takes place. Proton motive force generates ATP through the passive diffusion of protons through the enzyme ATP synthase, thus converting ADP and and inorganic phosphate group into high energy ATP molecules. These ATP molecules can drive other endergonic reactions in the cell.
What else can I help you with?
Is the etc in both cellular respiration and photosynthesis?
Yes, the electron transport chain (ETC) is involved in both cellular respiration and photosynthesis. In cellular respiration, the ETC is located in the inner mitochondrial membrane and is responsible for producing ATP by transferring electrons from NADH and FADH2 through a series of protein complexes. In photosynthesis, the ETC occurs in the thylakoid membranes of chloroplasts, where it helps convert light energy into chemical energy, ultimately leading to the production of ATP and NADPH. Both processes highlight the importance of the ETC in energy transformation within cells.
What are 3 organic compounds in cellular respiration?
The role of organic compounds in cellular respiration is to start cellular respiration. Cellular Respiration is a process that creates ATP. So, in order to create ATP you'll need organic compounds. Organic Compounds are converted into ATP during Cellular Respiration. This is the role of organic compound in cellular respiration.
How many total phases are in cellular respiration?
3: Glycolysis, Kreb's, ETC
Where is oxygen consumed in cellular respiration?
Oxygen is consumed in the electron transport chain of cellular respiration, specifically during the process of oxidative phosphorylation where it serves as the final electron acceptor. This occurs in the inner mitochondrial membrane where electrons are transferred through a series of protein complexes, ultimately generating ATP.
How much ATP does it cost to run cellular respiration?
For cellular respiration two ATP must be put into glycolysis which starts the whole process of cellular respiration Steps: 1. Glycolysis 2. Transition Stage 3. Kreb cycle 4. Electron Transport Chain (ETC)
Where is the majority of ATP produced during cellular respiration?
The majority of ATP is produced during cellular respiration in the mitochondria, specifically in the process of oxidative phosphorylation that occurs in the inner mitochondrial membrane. This process involves the electron transport chain and ATP synthase to generate ATP from the energy released by the movement of electrons.
What is the sequence of events in cellular respiration?
glycolysis, fermentation, Krebs cycle, ETC (Electron Transport Chain), Actually fermentation is not part of cellular respiration, and occurs only without oxygen, which cellular respiration depends on. -- Fermentation does occur, but only when no oxygen is present. It IS part of cellular respiration.
Why is ATP production during cellular respiration characterized as indirect?
ATP is not produced directly by the ETC but instead via the proton gradient generated during electron transport through the ETC.
Whice process of cellular respiration produces the most ATP?
The electron transport chain produces the most ATP during cellular respiration. It is the final stage of aerobic respiration and occurs in the inner mitochondrial membrane. Here, electrons are passed down a series of protein complexes, generating a proton gradient that drives ATP synthesis.
What are 3 organic compounds in cellular respiration?
The role of organic compounds in cellular respiration is to start cellular respiration. Cellular Respiration is a process that creates ATP. So, in order to create ATP you'll need organic compounds. Organic Compounds are converted into ATP during Cellular Respiration. This is the role of organic compound in cellular respiration.
What is the gas used during respiration?
Oxygen is the gas used during respiration. It is inhaled into the lungs and then transported via the bloodstream to cells where it is used to produce energy through the process of cellular respiration.
What are the biochemical processes at the cellular level that sustain life?
Nutrition, Digestion, Response, Excretion, Cellular Respiration, etc.
How many total phases are in cellular respiration?
3: Glycolysis, Kreb's, ETC
Water is produced during which stage in cellular respiration?
Water is produced during the electron transport chain stage of cellular respiration. It is a byproduct of the electron transport chain when oxygen is the final electron acceptor, leading to the formation of water molecules.
Where in the cell does respiration take place?
Most of cellular respiration occurs within the mitochondria of the cell. Glycolysis occurs outside of the mitochondria, while the Krebs Cycle and ETC takes place inside the mitochondria.
Why is cellular respiration aerobic?
The single most important biochemical especially to us is " Cellular respiration ". Because this is how we derive energy from what we eat and used in some metabolic reactions and muscle contraction, nerve impulses.or in simple "Cellular respiration" is process from which the organisms can derive energy from the metabolic reactions.cellular respiration is starts from glucose. During cellular respiration one mole of glucose and six moles of molecular oxygen going to produce six carbon dioxide, six water molecules, and energy and 38 ATP's ( energy currency for biological system )Under cellular respiration :1) Glycolysis/ anaerobic cellular respiration ( breaking up glucose; gluc= sweet, ose = sugar ): It occurs completely under the absence of oxygen. so it this is called " anaerobic cellular respiration ".where in Glycolysis the glucose molecule need 2ATP's and generates 2ATP's so it generates a net of 2 ATP's.the byproducts of glycolysis that re-engineeredand enters in to aerobic( requires oxygen ) cellular respiration process called ;2) Krebs cycle( aerobic cellular respiration ) : Krebs cycle generates another 2 net ATP's. This 2ATP's produces NADH.3) Electron transport chain/ ETC ( aerobic cellular respiration ) : ETC generates 34 ATP's by using the NADH which are produced from the ATP in Krebs cycle.this cycle requires oxygen so aerobic respiration.that's about cellular respiration and aerobic process ( 2nd and 3rd ).Here some important thing is some of the byproducts of the glucose ; instead of going in to Krebs and ETC cycle enters into a process called Fermentation and produces alcohol and lactic acid.( Yeast= alcohol, called alcohol fermentation)( Humans= lactic acid) .
Can a tiger do cellular respiration?
Yes, a tiger can perform cellular respiration as it is a vital process for obtaining energy from food molecules. Through cellular respiration, tigers convert nutrients into adenosine triphosphate (ATP) for energy production in their cells.
