What is converted to pyruvate in cellular respiration?
Via the enzyme 'pyruvate kinase' , phosphoenolpyruvate is combined with Adp and Pi to {100%} YIELD pyruvate [pyruvic acid] and Atp. Starting from Glucose, there are at least six separate [because each step "has" its own Enzyme to THOROUGHLY control the yield of the reaction] steps that precede the above.
In which organelle does aerobic cellular respiration take place?
aerobic respiration means the oxidation of nutrients using oxygen to produce energy. it is a 4 step process. step 1 The glucose is converted to pyruvate in the cytoplasm of the cell in te absence of oxygen. this process is called glycolysis. Each glucose molecule produces 2 molecules of pyruvate. 1 Glucose----> 2Pyruvate step 2 The pyruvate formed is converted to acetyl CoA in the cytoplasm. step 3 The acetyl CoA is sent to the mitochondria of the cell where it takes part in the Kreb's cycle. it occurs in the presence of O2 this acetyl CoA can easil enter the mitochondria which is the site for further reactions. step 4 the energy produced in the above steps is converted to ATP using ATP synthase enzyme. A total of 36 ATP molecules are produced. The overall reaction for aerobic respiration is Glucose------> Pyruvate-------> CO2 + H2O + 36ATP Energy
Name the two step process where pyruvate is converted to a two carbon compound releasing carbon dioxide. Then the electrons are transferred from a molecule of NADH to the two carbon compound producing?
Pyruvate decarboxylation -> Acetaldehyde reduction The product is ethanol. Pyruvate decarboxylation is performed by pyruvate decarxylase with cofactor thiamine pyrophosphate, and the product, acetaldehyde, is reduced by NADH. (Pyruvate decarboxylase is NOT the same as the pyruvate dehydrogenase complex in cellular respiration. Though pyruvate dehydrogenase also decarboxylates pyruvate, but the decarboxlated species immediately reacts with CoA to form acetyl-CoA).
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.
Is the first step aerobic respiration the first step in anaerobic respiration?
Yes
Where does acetyl CoA take place?
Acetyl-CoA is produced during the second step of aerobic cellular respiration. In the matrix of the mitochondria pyruvate decarboxylation occurs.
Where does the second step of cellular respiration happen?
In the Mitochondria
How are glycolysis and cellular respiring related?
Glycolysis breaks down glucose to form the reactants of cellular respiration

Where happen the first step of cellular respiration?
Glycolysis, where 1 glucose molecule (C6H12O6) splits into 2 pyruvate (C3H6O3) and produce 2 ATP.
What is the third step in aerobic respiration?
Assuming that you consider glycolysis the first stage and the link reaction (or oxidative decarboxylation of pyruvate) the second stage, then stage three would be krebs' cycle (or citric acid cycle).
Site of cellular resperation?
The first step of cellular respiration is glycolysis, which occurs in the cytoplasm and converts glucose to pyruvate. The remaining two steps, the Krebs cycle and oxidative phosphorylation, both occur in the mitochondria.
What the first step in cellular respiration is?
The first step to respiration is glycolysis.
The first step in cellular respiration is .?
The first step to respiration is glycolysis.
When does glycosis take place?
Glycolysis takes place in the cytoplasm of cells and is the first step in cellular respiration. It is a series of enzymatic reactions that break down glucose into pyruvate, producing a small amount of ATP in the process.
