How is ATP made in the cellular respiration process?

Answer 1

It is a very long and detailed process. Generally one glucose molecule gives 38 or 36 ATPs during aerobic respiration. While during anaerobic respiration only 2 ATPs are formed from single glucose molecule.

The ATP formation in respiration starts with glycolysis, in which one glucose molecule breaks into 2 pyruvic acid molecule. Then the pyruvic acid is converted to acetyl coA. This acetyl coA enters the Krebs cycle. Finally the NADH2 and FADH2 obtained during Krebs cycle go to electron transfer chain in which maximum ATPs are generated. This is applicable to aerobic respiration. In anaerobic respiration the pyruvic acid is reduced to alcohol and carbondioxide.

Answer 2

ATP is produced in a few different pathways in living systems. The major pathway is the electron transport chain, which produces 28-32 ATP. Electrons move down their gradient to pump hydrogens up their concentration gradient. As a result hydrogen then moves back down the gradient cause ATPsynthase to produce ATP compounds. ATP is also produced in glycolosis, which produces 2 net ATP (4 at the start but it uses 2), as well as the Krebs cycle, which produces 2). Between the biochemical respiratory pathways a net of 36 ATP is produced from one glucose molecule.

Pathway

Glucose enters glycolosis, glycolosis sends pyruvate to pyruvate processing produsing Acytel-CoA, Acytel-CoA enters the Krebs cycle producing electron carriers that lead to the electron transport chain with a final production of ATP.

Answer 3

Glycolysis:

1 Glucose molecule breaks down into 2 Pyruvate molecules

The process creates 4 ATP from 4 ADP, but used 2 ATP in the conversion (net gain 2 ATP).

The process also produces 2 NADH (from NAD+) which will later be oxidized in the electron transport chain.

Transient Reaction:

2 molecules of Pyruvate are converted to 2 molecules of Acetyl CoA and 2 CO2.

No ATP are produced in this step, but 2 NADH (from NAD+) are produced.

Kreb's Cycle:

1 molecule of Acetyl CoA produces 2 CO2. (The Kreb's Cycle turns twice for every molecule of glucose)

2 ATP are produced from ADP, as is 6 NADH (from NAD+) and 2 FADH2 (from FAD+). (1 ATP, 3 NADH and 1 FADH2 from one molecule of glucose)

Electron Transport Chain:

The 10 NADH and 2 FADH2 produced in the earlier reactions are oxidized back into NAD+ and FAD+. Through this process, every NADH oxidized produces 3 ATP, and every FADH2 oxides produces 2 ATP. Therefore the ATP gain in this process is 34. (10x3 + 2x2).

With 2 ATP netted in Glycolysis, 2 produced in the Kreb's cycle, and 34 produced through the Electron Transport Chain, the net production of ATP in cellular respiration is 38.

Answer 5

ATP is the energy for a cell and through the process of cellular respiration, 36 molecules of ATP are produced, therefore giving energy to carry out the functions of that particular cell.

Answer 6

ATP is the byproduct of cellular respiration, so is used by the cells as cellular energy.

Answer 7

The ATP is converted in to ADP and the energy released is utilized in various metabolic reactions of life supporting system.
