What is the link reaction in glycolysis?
The link reaction refers to the stage of respiration that “links” glycolysis to the Krebs (citric acid) cycle. In this stage, the products of glycolysis are converted into the reactants of the Krebs cycle. The final product of glycolysis is a pyruvate molecule.
Is the link reaction part of glycolysis?
There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation. During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
Where does the link reaction take place?
the mitochondrial matrix
The link reaction occurs in the mitochondrial matrix. It dehydrogenates and decarboxylates the three-carbon pyruvate to produce the two-carbon acetyl CoA that can enter the Krebs Cycle.
Why is link reaction needed?
The Link reaction is important as acetyl-CoA is needed for the Krebs cycle to happen.
What is produced in the link reaction?
The link reaction converts pyruvic acid to Acetyl-CoA. Carbon dioxide is released as a waste product, and one NADH is produced. The link reaction converts pyruvic acid to Acetyl-CoA. Carbon dioxide is released as a waste product, and one NADH is produced.
What does the link reaction do?
What is link reaction explain?
The Link reaction, also known as pyruvate decarboxylation forms an important link between the metabolic pathways of glycolysis and the citric acid or Krebs cycle. Pyruvate is decarboxylated: CO2 is removed. It is added to CoA to form Acetyl CoA.
Where is glycolysis take place?
the cytoplasm
Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
