Which molecule is formed when the protein ferrodoxin transfers electrons to an electron carrier? atp adp nadp+ nadph

NADPH

Explanation:

The formation of NADPH takes place in the following steps:

1. Electrons are transferred to the protein, ferrodoxin by the help of photosystem I in the presence of light. 

2. The electrons are shuttled by photosystem II to replace the electrons thus lost by photosystem I.

3. The electrons by ferredoxin are transferred to NADP+. 

4. NADP+ thus gets reduced and forms NADPH.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
