Stands for adenosine triphosphate
these are energy carrier molecules
Begins the breakdown of glucose(6-carbon sugar) producing 2 pyruvates(3-carbon sugar)
Also makes two ATP molecules
the two pyruvate, produced from glycolysis, are broken down into 6 CO2 molecules and 6 H2O molecules
When is Oxygen used in Cellular Respiration?
the last stage which produces an additional 34-36 ATP molecules for every 2 pyruvate molecules that enter the cycle.
Where does Cellular Respiration occur in Eukaryotic cell?
Mitochondria which are specialized for aerobic breakdown of pyruvate.
If oxygen is not available, the second stage of the glucose breakdown is____
pyruvate does not enter mitochondria like in cellular respiration
it instead remains in cytoplasm and is converted into either lactace, or into ethanol and CO2
Stands for Adenosine diphosphate
it is made from a energy-depleted ATP because it has one less Phosphate group
NAD / NADH
- NAD- nicotinamide adenine dinucleotide
- NADH- its NAD plus one H ion
these are high-energy electron-carriers
Citric Acid Cycle
also called Krebs Cycle
With 2 acetal CoA molecules, it will produce: 6 NADH, 2 FADH2, 2 ATP
