Glucogon is secreted from pancreas and mainly controls glycogenolysis.Glucagon is released from the pancreas in response to low blood glucose.

Glycolysis is the sequence of reactions that metabolizes one molecule of glucose to two molecules of pyruvate with the concomitant net production of two molecules of ATP. This process is anaerobic.

Glucose can be synthesized from noncarbohydrate precursors, such as pyruvate and lactic acid, in the process of gluconeogenesis. So gluconeogenesis generates glucose .

Glycolysis and gluconeogenesis are opposite steps to each other...But irreversible steps of glycolysis are bypassed in gluconeogenesis.

Glycolysis is anaerobic catabolism of glucose into pyruvate.

Glucose- Refers to monosaccharide simple sugar.
Glucagon - Hormone secreted by pancrease that raises blood sugar (glucose) levels (when blood sugar levels are low).
Gluconeogenesis - Glucose (gluco-) Synthesis (-neogenesis) ... synthesis of glucose when your body requires glucose.
Glycolysis - Glucose (Glyco-) Breakdown (-lysis) .. break down of glucose occurs once you have high sugar levels (after a meal).
Glycogenolysis: Glycogen (glycogen-) Breakdown (-olysis) ..breaks down glycogen to form glucose.

You can obviously go into details about each one but im guessing you're confused coz they all sound so similar. Just try to break down the words and make a meaning out of them. Hope this helps.

sorry one more question

immm sooo confused

the body uses glucose to create ATP rite?
then does it use gluconeogensis to create more glucose to create atp??

but some of the reactions are already in the pathway for making atp

ie glucose 6- phophatse to glucose??
