Question

What is the difference between interspecies hydrogen transfer and direct electron transfer as syntrophic mechanism? What type of symbiosis between two organisms is syntrophy? Please briefly explain your answer.

Answer 1

Question

Interspecies hydrogen transfer is the process of hydrogen transfer from one organism to another in the anaerobic requirement. On the other hand, direct electon transfer involve movement of free electrons from one cell to another cell without the use of reduced molecules.

In syntrophy is a mutualistic relationship exist between two organism who have different metabolically. So, syntrophy is a mutualistic relationship , which is a form of symbiosis relationship. Therefore, in syntrophy relatiinship, hydrogen atom is transfer from one organism to another which are showing mutula relationship is a interspecies hydtogen transfer whereas transfer of electron within the body of each organism is direct electron transfer.
