Respiration Rarámuri
Respiration Respiration occurs in 3 main steps
Respiration Respiration occurs in 3 main steps Glycolysis 6 carbon sugar is broken down into 3 carbon molecules of pyruvate
Respiration Respiration occurs in 3 main steps Glycolysis Krebs Cycle 6 carbon sugar is broken down into 3 carbon molecules of pyruvate Oxidizes pyruvate, enzymes rearrange atoms and bonds into ATP, NADH, and another electron carrier, FADH2
Respiration Respiration occurs in 3 main steps Glycolysis Krebs Cycle Electron Transport Chain 6 carbon sugar is broken down into 3 carbon molecules of pyruvate Oxidizes pyruvate, enzymes rearrange atoms and bonds into ATP, NADH, and another electron carrier, FADH2 Transfers high energy electrons from NADH and FADH2 through a series of membrane proteins to create a hydrogen ion gradient. Mitochondrion uses the potential energy in this gradient to generate ATP using ATP synthase (an enzyme)
