Activation energy 1 slows down the reaction. Complete answer: In cellular respiration oxygen and glucose are reactants that yield ATP. The byproducts are water and carbon dioxide. Aerobic respiration requires oxygen to create ATP. Glycolysis The main glycolysis events are as follows The bonds between glucose atoms and form pyruvate atoms. Various enzymes facilitate energy transfer from intermediates to ATP. Glycolysis steps An enzyme activates phosphate group transfer from ATP to glucose to form glucosephosphate and ADP Glucose 6 phosphate undergoes isomerization reaction to form fructose 6 phosphates.
Another enzyme facilitates phosphate transfer from ATP to fructosephosphate to fructose-bis-1,6- phosphate. An enzyme breaks to fructose-bis-1,6- phosphate into dihydroxyacetone and glyceraldehydephosphate. An enzyme converts dihydroxyacetone phosphate to glyceraldehydephosphate. An enzyme promotes phosphate transfer to ADP from form 1,3-bisphosphoglycerate. To form ATP and 3-phosphoglycerate. An enzyme allows bond rearrangement to form 2-phosphoglycerate.
Water is removed from 2-phosphoglycerate to form phosphoenolpyruvate. Phosphoenolpyruvate is then broken down into pyruvate molecules and ATP is formed.
The enzymes facilitate electron transfer from NADH to pyruvate making it become lactic acid. Lactic acid is a cell waste product. Alcohol fermentation : it is complex compared to lactic acid fermentation. Involves enzymes that transfer electrons to acetaldehyde from NADH converting it to ethanol. Krebs cycle The process occurs in the mitochondrion.
The pathway promotes the oxidation of food intermediates. Enzymes reduce electron carriers and oxidize food intermediates.
Enzymes promote the transfer of energy to ATP. Steps of Krebs cycle Enzymes combine acetyl-CoA with oxaloacetate to form citrate. An enzyme rearranges citrate bonds to form isocitrate. Succinyl-CoA is then converted to succinate. Succinate is oxidized to fumarate. Fumarate is then converted to malate. Malate is converted oxaloacetate. Transferring electrons along the electron transport chain Electron transport chains accept electrons from electron donors and pass them through protein complexes to a final electron acceptor.
The electrons move from one complex to another complex within the chain. Transferring energy from food to ATP Glycolysis and Krebs cycle enzymes transfer electrons from intermediates to electron carriers. Electron carriers that are reduced transfer electrons and energy to the electron transport chain. The complexes in the electron transport chain release energy while they pass through the chain.
The ATP synthase protein allows hydrogen ions to move through the membrane. Steps of the chemiosmotic theory of oxidative phosphorylation NADH donates energy and electrons to the electron transport chain. Electrons move in a series of redox reactions through the electron transport chain until they are picked by oxygen, the final electron acceptor.
ATP synthase enables the recrossing of ions to the inner mitochondrial membrane. How many ATP molecules are made from a single glucose molecule? Two ATP molecules are produced in glycolysis. Two ATP for a glucose molecule is produced in the Krebs cycle. Two NADH molecules are produced in glycolysis.
This total up to 4 ATP molecules. This is equal to 24 ATP. The food molecule intermediates are then oxidized they transfer their energy to ATP. Feeding complex carbohydrates into the system Simple sugars need very few reactions to convert them into intermediates of the glycolysis pathway. The cell respiration process digests the complex carbohydrate like starch common in human food t simple intermediates.
The amylase enzyme breaks the starch complex into glucose molecules that fit right in the glycolysis process. Burning fat Lipases break oils and fats into fatty acids and glycerol.
