A. A 4-carbon molecule is recycled.
B. Glucose is broken down into two pyruvate molecules.
C. Pyruvate is broken down into a 2-carbon molecule and carbon dioxide.
D. Citric acid is broken down, creating carbon dioxide as a waste product.

Respuesta :

the answer you are looking for is B. Glucose is broken down into two pyruvate molecules.

this process occurs during glycolysis

Glucose is broken down into two pyruvate molecules.

What is Krebs cycle ?

A sequence of reactions in the living organism in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds (as in ATP) — called also citric acid cycle, tricarboxylic acid cycle.

What is the end product of Krebs cycle ?

At the end of the Krebs cycle, the final product is oxaloacetic acid. This is identical to the oxaloacetic acid that begins the cycle. Now the molecule is ready to accept another acetyl-CoA molecule to begin another turn of the cycle.

In which process glucose breaks into pyruvate molecule ?

Glycolysis is the process by which glucose is broken down within the cytoplasm of a cell to form pyruvate. Under aerobic conditions, pyruvate can diffuse into mitochondria, where it enters the citric acid cycle and generates reducing equivalents in the form of NADH and FADH2.
