Why are 2 molecules of ATP used to start the process of anaerobic respiration?

The first of the two ATP molecules used in glycolysis is in the phosphorylation of free glucose by hexokinase in a cell. It does this to add a negative charge in order to keep the glucose molecules inside the cell regardless of the outside concentrations.
The second ATP molecule is consumed in the third step of glycolysis, in the phosphorylation of fructose-6-phosphate to fructose-1,6-biphosphate by the enzyme phosphofructokinase. This is generally considered the most important rate-determining step of glycolysis and is essentially irreversible under metabolic conditions.

Explain how cells obtain energy from cellular respiration?
Cellular respiration is a process that releases chemical energy from sugars and other carbon based molecules to make ATP when oxygen is present. It takes place in the mitochondria. :) -Biology Textbook
Difference between the two types of respiration?
Anaerobic does not need oxygen to occur, aerobic does. Both pathways start with the process of glycolysis.
What Process in Cellular Respiration requires 2 ATP to be invested?
Glycolysis cannot begin without two ATP molecules to start the process. Glycolysis yields 4 ATP molecules. Therefore, since 2 ATP molecules had been used up prior to the creation of the 4 ATP molecules, glycolysis has a net gain of 2 ATP molecules.
What molecule does cellular respiration start with?
Glucose and oxygen begin the process of respiration.
Which is more efficient in the terms of ATP production aerobic or fermentation?
Both start with glycolysis, which is an anaerobic process that produces a net gain of 2 ATP. Glycolysis can be followed by fermentation or aerobic respiration, depending on the organism and available oxygen for aerobic respiration. If glycolysis is followed by fermentation, no more ATP will be produced, so glycolysis and fermentation produce only 2 ATP for every glucose molecule. However, if aerobic respiration occurs, around 34 to 36 more molecules of ATP can be produced from every glucose molecule. So, aerobic respiration is much more efficient at producing ATP.
What chemical does it start with in anaerobic respiration?
aerobic respiration

Comparision between aerobic respiration and anaerobic respiration?
Aerobic respiration uses oxygen whereas anaerobic respiration does not need oxygen but it creates an oxygen debt and a dangerous by-product called lactic acid. Also aerobic last longer but it takes at least 60-90 secs so start working where as anaerobic respiration starts straight away.
The oxidation that occurs during cellular respiration differs from burning in that respiration?
In aerobic respiration, oxygen is used by the cells to achieve complete breakdown of carbohydrates to carbon dioxide & water; large quantities of ATP are produced. Anaerobic respiration takes place in the absence of oxygen; only the glycolysis sequence occurs, and much less ATP is produced.
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 prouduct is needed for cellular respiration?
Cellular respiration requires both glucose and oxygen. Glucose provides the energy for the cell and oxygen is required to be the final electron acceptor so that aerobic respiration can happen. Other molecules can enter cellular respiration and be broken down, but glucose is considered the start of this process. Oxygen is also not required, but if it is not present, then fermentation will run and this process is not nearly as efficient as aerobic respiration.
How is energy released during anaerobic respiration?
Since anaerobic is without oxygen, energy in cells produced anaerobically is without oxygen... so... Cells first start with Glycolysis, the beginning process in cell respiration that doesn't need oxygen. There it breaks glucose down into two pyruvic acid molecules. If there is no oxygen involved, the pyruvic acid is unused, and the original two ATP molecule break into four ATP molecules. From there, they travel into Fermentation. Depending on what you're doing, it may go into Alcoholic Fermentation or Lactic Acid Fermentation. Both produce several ATP molecules with the help of NADH. The products of both Fermentations are Carbon Dioxide (CO2) and NAD+, and also either alcohol or lactic acid.
What molecule does cellular respiration start with?
Glucose and oxygen begin the process of respiration.
What is common between aerobic and anaerobic respiration?
I can give you five similarities :) (please excuse my spelling, dyslexic)Both processes realease energyBoth start with a breakdown of nutrientBoth yield productsboth take place in a cellBoth involve PyruvatesHope this helped! :D
What process preformed by the peas when they start to grow causes the drop of liquid to move to the left?
Cellular respiration is performed by peas when they start to grow.
