A cycle has no beginning or end...
But if you are referring to the end product that is recombined to form the first product of the cycle, it is oxaloacetate.
Oxaloacetate is a 4-carbon compound that binds to the 2-carbon compound, acetyl-CoA, which is derived from the link reaction after glycolysis. After binding to acetyl-CoA and Coenzyme A leaves the compound, the resulting product is a 6-carbon compound, citrate. Citrate is eventually decarboxylated and oxidised to form oxaloacetate once more.
Intermediates are compounds formed within a metabolic pathway(which is a group of biochemical reactions that occur in a sequence- Anabolic or catabolic)
oxoloacetate
Citrate
Pruvate
citrate
The end products of glycolysis enter the Kreb's Cycle or Citric Acid Cycle.

After entrance of pyruvic acid into Kreb's cycle the four products are.. two molecules of ATP six molecules of NADH two molecules of FADH2 four carbon-dioxide
kreb cycle is second stage of cellular respiration they begining and end is same point. during kreb cycle they creat ATP and they also create NADHmolecule and FADH2 ATP, NADH and FADH2 is main product of kreb cycle
Assuming that the Kreb cycle starts with the citrate, the third compound is alpha-ketoglutarate.
NADH FADH and GTP .
The end products of glycolysis enter the Kreb's Cycle or Citric Acid Cycle.
most become reactants in the electron transport chain
most become reactants in the electron transport chain
For one glucose molecule, 2ATP+4CO2+6NADH2+2FADH2

They are the end products of glycolysis. ** ^wrong, in between glycolysis and the kreb's cycle is pyruvic acid oxidation

The main job of Kreb cycle is to generate energy. It is a part of cellular respiration.
Acetyl CoA (acetyl group) is the compound that enters the Kreb Cycle.
electrons, protons, CO2 and water. btw it is not "kreb cycle" but Krebs cycle (mr. Hans Krebs discovered it ;)
