What reactions coupled ATP synthesis?
What reactions coupled ATP synthesis?
ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
Why is ATP production a coupled reaction?
ATP is the major ‘energy’ molecule produced by metabolism, and it serves as a sort of ‘energy source’ in cell: ATP is dispatched to wherever a non-spontaneous reaction needs to occurs so that the two reactions are coupled so that the overall reaction is thermodynamically favored.
What is ATP coupled process?
ATP hydrolysis is coupled to a work-requiring (energetically unfavorable) process through formation of an unstable, phosphorylated intermediate, allowing the process to take place in a series of steps that are each energetically favorable.
What is the simple equation for reforming ATP?
adp
What types of cells in the body require the most ATP?
The types of cells in the body that I would expect to require the most ATP are muscle cells. Muscle cells require larger amounts of ATP. They are responsible for all of our movements. Most of the energy burned during your day is through movement of your body by skeletal muscles.
What step in cellular respiration requires oxygen?
Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.
What is the process by which cells release energy in the absence of oxygen?
Fermentation releases energy from food molecules by producing ATP in the absence of oxygen. During fermentation, cells convert NADH to NAD+ by passing high-energy electrons back to pyruvic acid.
What is the net gain of ATP during glycolysis?
Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy.
What is the net gain of ATP during aerobic respiration?
There is net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose. But in most eukaryotic cells, 2 molecules of ATP are required for transporting the NADH produced in glycolysis into the mitochondrion for further oxidation. Hence, net gain of ATP here is 36 molecules.
How many net ATP are formed in aerobic glycolysis?
4 molecules
What is the correct order of steps for cellular respiration?
Ch. 9 Honors Biology Cellular Respiration
| Question | Answer |
|---|---|
| What is the correct sequence of stages of cellular respiration? | glycolysis, Krebs Cycle, Electron Transport Chain |
| What is the correct equation for cellular respiration? | C6H12O6 + 6 O2 –> 6 CO2 + 6 H2O |
| What are the products of cellular respiration? | CO2, H2O, ATP |
Which step in cellular respiration produces the most ATP?
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.
