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.
In the second stage of cellular respiration, pyruvate is transported into the mitochondria, where it enters the citric acid cycle (also known as the Krebs cycle). Within the citric acid cycle, pyruvate is further broken down to generate energy in the form of ATP.
When oxygen is present, pyruvate molecules produced in glycolysis enter the second stage of cellular respiration, which is the citric acid cycle (Krebs cycle). In this cycle, pyruvate is converted to acetyl CoA, which then enters the citric acid cycle to generate ATP through a series of redox reactions.
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
The stage of cellular respiration that produces the least amount of ATP is glycolysis. During glycolysis, which occurs in the cytoplasm, a net gain of only 2 ATP molecules is produced per glucose molecule. This process breaks down glucose into pyruvate, but the majority of ATP is generated in subsequent stages, such as the citric acid cycle and oxidative phosphorylation.

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

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
NADPH is the other molecule produced in the second stage of photosynthesis, known as the light-dependent reactions. Both ATP and NADPH are essential for the production of sugars in the Calvin cycle, which is the third stage of photosynthesis.
Electron transport chain reactions
Most of the ATP is produced during the electron transport chain stage of cellular respiration. This is where the majority of ATP molecules are generated through oxidative phosphorylation using energy released from the transfer of electrons along the electron transport chain.
The most important stage of cellular respiration is the electron transport chain, where the majority of ATP is produced. This stage relies on the transfer of electrons from NADH and FADH2 to generate a proton gradient across the inner mitochondrial membrane, driving ATP synthase to produce ATP.
