Question

The hydrogen donor in bacterial photosynthesis is usually
A) Water
B) Hydrogen sulphide
C) Sulphurus acid
D) Ammonia

Answer 1

Answer:

The correct answer of this question is option B, hydrogen sulphide.

Explanation:

Bacterial photosynthesis is mostly similar to the normal plant synthesis.

Similarly, the bacterial photosynthesis also uses the hydrogen molecules for the photosynthesis reactions,just like the normal plant photosynthesis.

And the donor of hydrogen in the bacterial photosynthesis is the hydrogen sulphide.

Answer 2

Answer:

The hydrogen donor in bacterial photosynthesis is usually B) Hydrogen sulphide.  

Explanation:

The bacterial photosynthesis happens in sulphur bacteria by reducing hydrogen sulphide present in the material. This is similar to the oxygenic photosynthesis that takes place in terrestrial plants except for the place where the reductant or the hydrogen donor is hydrogen sulphide rather than water.  

These bacteria which utilized hydrogen sulphide are mostly anaerobic in nature and are found in hot springs or stagnant water.
