Respiration releases what amount of energy Large or small?
Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.
Give the two stages of cellular respiration?
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
Citric acid forms during which part of cellular respiration?
Citric acid forms during the electron transport chain and citric acid cycle in cellular respiration. Citric acid is a six-carbon acid.
What is the second stage in cellular respiration?
The second stage of cellular respiration is the transition phase. It links glycolysis with the Kreb's cycle. At this stage, the pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
List and explain the two types of cellular respiration?
the two main types of cellular respiration are aerobic cellular respiration and anaerobic cellular respiration.
What is the second of cellular respiration?
actually there are two types of cellular respiration:aerobic and anaerobic. aerobic cellular respiration only takes place when there is a presence of oxygen, while anaerobic or also called as fermentation takes place even w/out oxygen.

What is the second main part of cellular respiration?
The second stage of cellular respiration is the Citric acid cycle (or Kreb's cycle or tricarboxylic acid cycle). It occurs in the matrix of mitochondria. This cycle yields electrons which are needed for producing ATP in the later step ETC and oxidative phosphorylation.The second stage of cellular respiration is can be two things. If there is oxygen present, then cellular respiration is called aerobic respiration. The second stage of aerobic respiration is the Kreb's cycle, in which pyruvate is used to created two molecules of ATP, as well as releasing some carbon dioxide. If there is no oxygen present, then cellular respiration is called anaerobic respiration. The second (and final) stage of anaerobic respiration is fermentation. The two types of fermentation are alcohol fermentation and lactic acid fermentation. They produce alcohol and lactic acid respectively. For example, when you exercise, you may start to feel a burning in your muscles. This is your cells using lactic acid to create ATP for energy, since they aren't receiving enough oxygen to go through aerobic respiration.
Where in the cell does the second stage of respiration?
The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.
Is kerbs cycle part of cellular respiration?
Ya, it is the second stage in respiration.
Where does the second step of cellular respiration happen?
In the Mitochondria
Where does the produced pyruvate go in the second stage of cellular respiration?
Pyruvate enters mitochondria for further stages of cellular respiration such as Kreb's cycle and ETC.
Give the two stages of cellular respiration?
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
What is the other by product for cellular respiration water and what is the second?
Carbon dioxide
Where in respiration does the second stage happen?
The second stage of cellular respiration, after glycolysis, occurs in the mitochondria. All of the stages of cellular respiration (after glycolysis in the cytoplasm) occur in the mitochondria.
Why is respiration essential for life?
Respiration is not essential for life. Many forms of bacteria do not undergo cellular respiration and are still considered 'alive'. Respiration, more specificially cellular respiration, is just one of many ways (although one of the more energetically efficient ways) for a cell to produce energy. Human cells are capable of producing energy in one of two ways, depending on the condition the cells are placed in. The most common of the two ways is through cellular respiration. This occurs when there is sufficient oxygen being carried to the cells via the blood. The second occurs when the body's cells do not have enough oxygen to support cellular respiration. This is commonly experienced during heavy workouts. When the body's cells don't have the needed oxygen to undergo cellular respiration, the cells revert to a form of energy creation called 'fermentation,' which DOES NOT require oxygen. Fermentation causes the build-up of lactic acid in muscle cells, which leaves that sore feeling in your muscles after a workout.
