What three things must be present in order for respiration to occur?
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
Which steps in respiration require oxygen?
All three of the basic steps INSPIRATION, VENTILATION and PERFUSION although 1/2 of the 2nd phase or VENTILATION process requires no oxygen and it is the expiration of carbon dioxide from the body through the lungs.
Where is the last three stages of cellular respiration?
The last three stages of cellular respiration occur in the mitochondria. They are the citric acid cycle (Krebs cycle), electron transport chain, and oxidative phosphorylation. These stages involve the production of ATP, the cell's main source of energy.
What are three wastes a cell releases?
Cells release several waste products during metabolic processes. Three common wastes include carbon dioxide, which is produced during cellular respiration; urea, a byproduct of protein metabolism; and metabolic acids such as lactic acid, which can accumulate during anaerobic respiration. These wastes must be efficiently removed to maintain cellular health and homeostasis.
Are only 2 ATPs produced for each NADH molecule that enters the last stage of respiration?
The NADH molecule produces of 2 ATPs during the last stage of respiration. Some think that three ATPs are created from the NADH, however, the last stage of respiration is different than ATP and NADH during electron transfers.
What is the by product if cellular respiration is not able to get through all three steps?
Lactic acid.
Does respiration occur in the mitochndria?
Two of three parts of aerobic respiration take place in mitochondria.Kreb cycle and electron transport chain.
What are the three processes that occur during cell respiration?
The three processes that occur during cell respiration are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain). Glycolysis breaks down glucose into pyruvate, the citric acid cycle further breaks down pyruvate to produce ATP and electron carriers, and oxidative phosphorylation uses these electron carriers to generate most of the ATP through a series of redox reactions.
Six carbons enter the second stage of aerobic respiration how many depart during the preparation steps and the cycle proper?
During the preparation steps in the second stage of aerobic respiration (Krebs cycle), two carbons depart as carbon dioxide in the conversion of pyruvate to acetyl-CoA. In the cycle proper, all six carbons that entered are released as carbon dioxide molecules in the form of three molecules of CO2.
What three things must be present in order for respiration to occur?
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
What are the two steps in aerobic respiration that produce ATP?
The two steps in aerobic respiration that produce ATP are glycolysis and oxidative phosphorylation. Glycolysis generates a small amount of ATP directly, while oxidative phosphorylation, which occurs in the mitochondria, produces the majority of ATP through the electron transport chain and ATP synthase.
What three things are made during cellurlar respiration?
glucose water and oxygen
What makes up respiration?
It occurs in three steps 1. Glycolysis, 2. Kerbs cycle, 3. Electron transport chain
Which steps in respiration require oxygen?
All three of the basic steps INSPIRATION, VENTILATION and PERFUSION although 1/2 of the 2nd phase or VENTILATION process requires no oxygen and it is the expiration of carbon dioxide from the body through the lungs.
What are the 3 stage of respiration?
The three stages of cellular respiration are glycolysis, Krebs cycle, and electron transport chain. During glycolysis glucose is split into two different molecules.
Where is the last three stages of cellular respiration?
The last three stages of cellular respiration occur in the mitochondria. They are the citric acid cycle (Krebs cycle), electron transport chain, and oxidative phosphorylation. These stages involve the production of ATP, the cell's main source of energy.
What three thing are produced during the second step of respiration?
Carbon dioxide (CO2), Water (H20), and Energy
