Question

Please explain Glycolysis and Krebs Cycle for 9th grade ICSE... (cellular respiration) briefly in simple words... :-)

Answer 1

Answer:

Glycolysis is the process of Lysis of glucose and the reaction gives 2 ATP

Answer 2

Glycolisis

Cells make energy by breaking down macromolecules.

Cellular respiration is the biochemical process that converts “food energy” (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP).

The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from Latin glyco (sugar) and lysis (breakdown).

Glycolysis serves two main intracellular functions:

generate ATP and intermediate metabolites to feed into other pathways. The glycolytic pathway converts one hexose (six-carbon carbohydrate such as glucose), into two triose molecules (three-carbon carbohydrate) such as pyruvate, and a net of two molecules of ATP (four produced, two consumed) and two molecules of nicotinamide adenine dinucleotide (NADH).
