Which of the following particles can pass through the ATP synthase channel?
ATP synthase is a key enzyme complex involved in the production of ATP (Adenosine Triphosphate), the cellular energy currency in organisms
ATP synthase is a key enzyme complex involved in the production of ATP (Adenosine Triphosphate), the cellular energy currency in organisms. It is located in the inner mitochondrial membrane in eukaryotic cells and the plasma membrane of prokaryotic cells.
The ATP synthase channel is divided into two main subunits: F0 and F1. The F0 unit spans the membrane and consists of a ring of c-subunits. It functions as a channel through which ions can flow. The F1 unit is located on the matrix side of the membrane and contains the enzymatic sites for ATP synthesis.
For the ATP synthase channel, only ions are able to pass through. Specifically, protons (H+) are the ions that pass through the channel in most organisms. The passage of protons through the ATP synthase allows for the synthesis of ATP from ADP (Adenosine Diphosphate) and inorganic phosphate.
Other particles, such as larger molecules or ions with different charges (e.g., sodium, potassium), are unable to pass through the ATP synthase channel due to its specific structure and the requirement for proton flow in the process of ATP synthesis.
In summary, only protons (H+) can pass through the ATP synthase channel, allowing for the generation of ATP.
