distinguish between glycolysis and TCA cycle
Answers
The main difference between glycolysis and Krebs cycle is:Glycolysis is the first step involved inthe process of respiration and occurs in the cytoplasm of the cell. ... SoGlycolysis is defined as the chain ofthe reactions, for the conversion of glucose (or glycogen) into pyruvate lactate and thus producing ATP.
Respiration is a process which occupies a series of reactions which are coupled by oxidation and reduction reactions and electron transfer. At the end of the respiration, organisms produce energy to utilize for their metabolic processes. This energy is produced in the form of ATP (energy currency of the cells). During aerobic respiration, oxygen molecules act as the final electron acceptors and are reduced to produce water. This creates an electrochemical gradient which drives the ATP synthesis. Aerobic respiration consists of three main phases, where carbon molecules are rearranged through a series of enzyme catalyzed reactions to yield ATP. The first phase, common to both aerobes and anaerobes, is the glycolytic pathway where sugar substrate, mainly glucose, is catabolized to two pyruvate molecules. This conversion produces two ATP molecules and two NADH molecules.
GLYCOLYSIS.
1)the process of glycolysis occurs in cytoplasm.
2)in glycolysis one molecule of glucose is oxidized step-by-step to produce two molecules of each pyruvic acid ATP energy, NADH2 and water.
3)glycolysis can take place in both aerobic and anaerobic respiration.
4)two molecules of ATP are used in it.
5)four molecules of ATP are produced in glycolysis
TCA CYCLE.
1)TCA cycle takes place in mitochondria.
2)in TCA cycle molecule of acetyl coenzyme a is completely oxidised in the process CO2, H2O, NADH2, FADH2 and ATP is formed
3)TCA cycle only takes place in aerobic respiration
4)ATP molecules are not used in TCA cycle.
5)2 ATP molecules are formed in TCA cycle.
