The NADH molecule produces of 2 ATPs during the last stage of respiration. Some think that three ATPs are created from the NADH, however, the last stage of respiration is different than ATP and NADH during electron transfers.
Pyruvate enters mitochondria for further stages of cellular respiration such as Kreb's cycle and ETC.
Mitochondria
Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. No oxygen is needed for this stage of respiration and it occurs in cells that respire using mitochondria and cells that ferment sugars.
Electron transport chain reactions
Cellular respiration produces ATP from the breakdown of glucose. ATP, NADH, and FADH2 are produced in Glycolysis. NADH and ATP are produced in the Krebs cycle. And 32 ATP and water are produced in the Electron Transport Chain. The first stage of respiration, glycolysis, occurs in the cytoplasm. The later stages occur in the mitochondria.

the first answer was: 38 ----------- this is not true. during the kreb cycle, only 2 ATP molecules are produced from 1 molecule of glucose [2-3 pyruvic acid molecules]. During all of respiration, 1 glucose molecule is eventually broken down to make 36 ATP total. the three main parts of respiration [for beginning learners] is: Stage 1: glycosis: 2 ATP produced stage 2: kreb cycle: 2 ATP produced stage 3: electron transport chain: 32 ATP produced in total: 36 ATP is produced in respiration
The stage of cellular respiration in which most ATP is produced is the electron transport chain.
the kreb's cycle
In the Electron Transport System
Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. No oxygen is needed for this stage of respiration and it occurs in cells that respire using mitochondria and cells that ferment sugars.
First stage is Glycolysis pyruvate is then turned into Acetyl CoA and enters the Krebs Cycle Second stage is Krebs Cycle Third stage is Electron transport chain

ATP and NADPH are produced during photosystems I and II of the light phase of photosynthesis.
