How many molecules of ATP can a cell extract without oxygen?
During anaerobic respiration, a cell can extract two molecules of ATP per molecule of glucose through glycolysis. It does not require oxygen to generate ATP through this process.
How many ATP molecules in the presence of oxygen can be produced?
In aerobic respiration, 36 or 38 molecules of ATP per molecule of glucose, depending on how many are gained through the electron transfer system.In anaerobic respiration 2 molecules of ATP per molecule of glucose, though higher yields can occur in higher temperatures (as much as 9 ATP molecules per molecule of glucose)
What type of respiration yields more ATP why?
Aerobic respiration yields more ATP compared to anaerobic respiration. This is because aerobic respiration involves the complete oxidation of glucose in the presence of oxygen, producing about 30 to 32 ATP molecules per glucose molecule. In contrast, anaerobic respiration, which occurs without oxygen, only generates about 2 ATP molecules per glucose, as it relies on fermentation processes that do not fully oxidize glucose.
How many ATP molecules are formed for each fadh2 and nadh?
FADH2 allows for the formation of 2 molecules of ATP during the Kreb's cycle.
What type of respiration are muscle fibers using when they use oxygen to release the energy stored in ATP molecules?
When muscle fibers use oxygen to release the energy stored in ATP molecules, they are engaging in aerobic respiration. This process involves the breakdown of glucose in the presence of oxygen to produce ATP, carbon dioxide, and water. Aerobic respiration is more efficient than anaerobic methods, allowing for sustained energy production during prolonged physical activity.
What forms as an energy source when respiration occurs in the presence of oxygen?
The energy source formed during respiration in the presence of oxygen is ATP (adenosine triphosphate). ATP is created through the process of cellular respiration, where glucose is broken down in the presence of oxygen to produce energy in the form of ATP molecules.
The complete breakdown of glucose in the presence of oxygen yields how many molecules of ATP?
The complete breakdown of glucose in the presence of oxygen, through cellular respiration, yields a total of 36 molecules of ATP. This process includes glycolysis, the citric acid cycle, and oxidative phosphorylation in the electron transport chain.
How is ATP formed in living organisms?
ATP is formed in living organisms through a process called cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the main energy source for cells. This process occurs in the mitochondria of cells and involves a series of chemical reactions that ultimately convert the energy stored in glucose into ATP molecules.
How many molecules of ATP are gained by substrate-level phosphorylation from the complete breakdown of a single molecule of glucose in the presence of oxygen?
In substrate level phosphorylation, the ADP is phosphorylated directly by the transfer of phosphate group from substrate. If we consider glucose, then we get four substrate level phosphorylated ATPs, net gain of two in glycolysis and other two are formed when the two pyruvate molecules formed after glycolysis enter the TCA cycle.
Why can 18 times as much ATP be generated from glucose in the presence of oxygen than when oxygen in not available?
The Krebs Cycle and ETC enable the cell to produce 34 more ATP molecules per glucose. The 62 percent of the total energy of glucose that is not used to make ATP molecules is released as heat.
How many ATP total are produced from one glucose molecule in the presence of oxygen?
In the presence of oxygen, one glucose molecule can produce a total of 36-38 molecules of ATP through cellular respiration. This process involves glycolysis, the Krebs cycle, and the electron transport chain.
Cells produce ATP most efficiently in the presence of what molecule?
Oxygen. Cells can produce much more ATP from glucose in the presence of Oxygen (aerobic respiration) than without oxygen (anaerobic respiration) in a process called oxidative phosphorylation that occurs in the mitochondria of cells. In the presence of oxygen one glucose can be broken down to produce 36 ATP Without oxygen, only 4 ATP can be made
Why is more ATP generated from glucose in the presence of oxygen?
when oxygen is not available, the Krebs cycle and electron transport cannot produced, and glycolysis produces just 2 ATP molecules per glucose molecule, under acerbic conditions, the Krebs cycle and electron transport enable the cell to produce 34 more ATP molecules per glucose molecule
Why is more ATP genarated from glucose in the presence of oxygen?
More ATP is generated from glucose in the presence of oxygen because of aerobic respiration. During this process, glucose is fully broken down in the mitochondria, leading to the production of more ATP molecules through the electron transport chain and oxidative phosphorylation. Oxygen acts as the final electron acceptor, allowing for a more efficient generation of ATP compared to anaerobic respiration.
How many ATP molecules are formed during cellular perspiration?
36 ATP
What provides the energy for the cell to move?
Cells typically use adenosine triphosphate (ATP) as their primary source of energy to fuel movement. ATP is produced through cellular respiration, where glucose is broken down in the presence of oxygen to generate ATP molecules. These ATP molecules are then used by cellular proteins to power movement within the cell.
How many ATP are made with oxygen?
In the presence of oxygen, the process of aerobic respiration can produce up to 36-38 molecules of ATP per molecule of glucose. This occurs through a series of metabolic pathways, including glycolysis, the Krebs cycle, and oxidative phosphorylation in the mitochondria.
