Why is aerobic respiration preferred by cells?
Cause its more efficient.It yields about 40% of glucose molecule's energy. Anaerobic respiration yields 18 times less
What stage of cellular respiration yields to the most ATP?
NADH. In oxidative phosphorylation, for every NADH, around 2.5 ATP molecules are made, and for every FADH2 about 1.5 ATP molecules are made.
What has more energy ATP or sugar?
One molecule of glucose yields ~ 38 ATP, so sugar has much more energy tied up in its bonds than one ATP.
Monosaccharides produced by hydrolysis of sucrose?
You have the enzyme called as sucrase. This enzyme is present in the brush border of the cells from intestine. This enzyme splits one molecule of sucrose into one molecule of glucose and one molecule of fructose. This reaction takes place during absorption.
Why is cellular respiration more efficient when oxygen is present in cells?
Without oxygen - only glycolysis occurs. This results in very few ATP molecules. With oxygen, all of celluar respiration occurs and this results in almost 40 ATP molecules. So, oxygen is essential to the production of mass ATP molecules.
In glycolysis what is the number of NADH produced?
Glycolysis is the breakdown of glucose by enzymatic action. It yields 2 NADH molecules and 2 ATP molecules per glucose molecule.
The portion of aerobic respiration that produces the most ATP per molecule of glucose is?
Cellular RespirationSource: Holt Biology by Johnson Raven* Aerobic cellular respiration. Anaerobic cellular respiration yields a net gain of 2 ATP molecules for each glucose molecule broken down. Aerobic respiration yields a variable number, but always more than ten times as many ATP molecules.
What chemical enters the mitochondria to continue respiration?
In aerobic respiration of glucose in eukaryotes, two molecules of pyruvic acid is produced in the cytoplasm by glycolysis of one molecule of glucose. The pyruvic acid then enters the mitochondria to go through the Krebs cycle, which will break down the pyruvic acid into carbon dioxide, which is then excreted. Putting a molecule of pyruvic acid through the Krebs cycle yields 1 molecule of ATP (2 ATP per glucose), but importing the pyruvic acid into the mitochondria costs 1 ATP molecule, so the net gain of ATP from the Krebs cycle is +0. Hydrogen ions and high-energy electrons from glycolysis also need to be imported into the mitochondria to the electron transport chain, which is where the mother-lode of ATP comes from (34 ATP per glucose molecule). Other molecules such as fatty acids and amino acids typically don't undergo glycolysis, but instead are imported directly into the mitochondria where they enter the Krebs cycle somewhere depending on their molecular structure.
What determines if cellular respiration or fermentation will take place?
The Oxygen molecule determines if the Pyruvic acid enters Krebs cycle or undergoes fermentation. If Oxygen is present, it enters the Krebs cycle, whereas in its absence, it undergoes fermentation.
How many ATP molecules are produced from one glucose molecule?
In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle. The net gain is 36 ATP, as two of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD. Therefore; There are 38 ATP molecules produced but net gain is 36 ATP
Does aerobic respiration form the greatest number of ATP molecules?
Yes. Anaerobic respiration yields a net gain of 2 ATP per molecule of glucose, while aerobic respiration yields 36 -38 ATP per molecule of glucose.
How many ATP molecules are produced from one glucose?
In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle. The net gain is 36 ATP, as two of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD. Therefore; There are 38 ATP molecules produced but net gain is 36 ATP
What come after glycolysis?
After glycolysis you will go through bridging reaction to the Krebs cycle, also known as the citric acid cycle because of the use of citric acid. the reducing power generated indirectly helps to power oxidative phosphorylation that occurs, which yields a total of 34 ATP's from one glucose molecule. Good luck
How many Acetyl coenzyme A molecules are generated from one molecule of glucose?
2: Two molecules of acetyl CoA molecules are produced by one glucose molecule, since each full round of the citric acid cycle yields one, and it takes 2 full completions because glucose yields two pyruvates. (:

Cause its more efficient.It yields about 40% of glucose molecule's energy. Anaerobic respiration yields 18 times less
What does glycolysis yield to net ATP?
Glycolysis yields two net ATPs
What is the source of energy for the first step of glycolysis?
ion of a three-carbon organic acid
