ATP formation occurs through which of the following processes?

ATP formation occurs through which of the following processes?
  1. Photophosphorylation
  2. Substrate level phosphorylation
  3. Oxidative phosphorylation
  4. All of these

Solution

Adenosine triphosphate (ATP) is formed through the following processes: Photophosphorylation This process occurs during photosynthesis and uses light energy to convert ADP into ATP. Oxidative phosphorylation This process occurs in the mitochondria and involves transferring electrons through electron carriers to produce ATP. It's the main source of ATP in aerobic organisms. Substrate-level phosphorylation This process converts higher energy to lower energy to form ATP. It produces a smaller amount of ATP than other processes and doesn't involve mitochondria or electron carriers.
