In summary, indirect atp formation refers to the process of generating ATP through oxidative phosphorylation in the electron transport chain, using the H+ gradient to attach inorganic phosphate to ADP. This is in contrast to direct atp synthesis, which involves substrate level phosphorylation where a molecule directly donates a phosphate to ADP. In indirect atp synthesis, the phosphate does not have to come from the molecule itself, but the energy released during the conversion aids in adding the phosphate group. This process is facilitated by PMF (proton motive force) and oxysomes (FoF1 particle).

I came across a term "indirect atp formation"I am not sure what it is ?
What is the difference between direct and indirect atp synthesis?I think substrate level phosphorylation (where a molecule directly donates a phosphate to ADP) is direct atp synthesis.Indirect atp synthesis is oxidative phosphorylation (in the electron transport chain; using the H+ gradient to attach inorganic phosphate to ADP).
Right?

The phosphate need not come from the molecule, the energy liberated during the conversion might just help in adding that Pi to ADP/GDP, eg:succinyl CoA to succinic acid in kreb's cycle.

Yes, by PMF(proton motive force) and oxysomes(FoF1 particle)
 

1. What is Indirect ATP Formation?

Indirect ATP formation is a process by which ATP (adenosine triphosphate) is produced through the breakdown of other molecules, such as glucose, in a series of chemical reactions.

2. How does Indirect ATP Formation contribute to cellular energy production?

Indirect ATP formation is a vital part of cellular energy production as it allows cells to efficiently convert the energy stored in molecules like glucose into usable energy in the form of ATP.

3. What are the main pathways involved in Indirect ATP Formation?

The main pathways involved in Indirect ATP formation are glycolysis, the Krebs cycle, and oxidative phosphorylation. These processes occur in the cytoplasm and mitochondria of cells.

4. What are the key molecules and enzymes involved in Indirect ATP Formation?

The key molecules involved in Indirect ATP formation are glucose, pyruvate, NADH, and FADH2. The key enzymes involved in this process include hexokinase, phosphofructokinase, and ATP synthase.

5. How is Indirect ATP Formation regulated in cells?

Indirect ATP formation is regulated by various factors, including the availability of substrates and enzymes, as well as feedback inhibition. Hormones and other signaling molecules can also influence the rate of Indirect ATP formation in cells.
