19 Ιουλ 2024 · ATP can also be produced without oxygen (i.e., anaerobic), which is something plants, algae, and some bacteria do by converting the energy held in sunlight into energy that can be used by a cell via photosynthesis.
31 Οκτ 2023 · The electron transport chain, where the majority of ATP is formed, requires a large input of oxygen. However, many organisms have developed strategies to carry out metabolism without oxygen, or can switch from aerobic to anaerobic cell respiration when oxygen is scarce.
23 Οκτ 2020 · This is why air-breathing organisms die so quickly without a constant supply of oxygen: our cells cannot generate enough energy to stay alive without it. Instead of oxygen, anaerobic cells use substances such as sulfate, nitrate, sulfur, and fumarate to drive their cellular respiration.
Overview of oxidative phosphorylation. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.
In aerobic respiration, the final electron acceptor is an oxygen molecule, O 2. If aerobic respiration occurs, then ATP will be produced using the energy of high-energy electrons carried by NADH or FADH 2 to the electron transport chain.
If aerobic respiration occurs, then approximately 30 molecules of ATP will be produced during the electron transport chain and chemiosmosis using the energy of the high-energy electrons carried by NADH or FADH 2 to the electron transport chain.
