What is the molecule that enters glycolysis?

Answer 1

short answer: Glycerol can enter the Glycolysis as DHAP.

longer answer: The oxidation of triglicerides to fatty acids and glycerol occurs in the cytoplasm. After that, glycerol is phosphorylated and enters glycolysis, while fatty acids are oxidised elsewhere. The oxidation of fatty acids in its common form(beta-oxidation) occurs in mitochondria and in peroxisomes. Glycogen and fatty acids are stored locally. When needed, they are broken down, with the energy used by the cell or exported.

Answer 2

in the body gylcerol is stored as the polymer triglyceride. This is first catabolised into individual glycerol monomers. glycerol does not enter into the Krebs cycle directly but is first converted into dihydroxyacetone phosphate and isomer of glyceraldyde 3-phosphate. it is then converted through reacting with the enzyme triose phosphate isomerise, into glyceraldyde 3-phosphate. this is and intermediat of glycose and can be entered into the glycolysis metabolic pathway, where from it follows the normal stepwise conversion to pyruvate and then to an acetyl group, which may be bonded to acetyl-CoA and entered into the kreb cycle by reaction with oxaloacetate

Answer 3

Glucose.

Glycolysis splits glucose into three-carbon molecules and makes two molecules of ATP.

Answer 4

Attached to coenzyme A as acetyl-CoA. This is the molecule that enters the Krebs

Answer 5

Yes

Pyruvater-----> Acetyl coa
