Question

Examples of endergonic reactions/ processes is/ are

1. chemotaxis
2. Transcription
3. H+ gradient generation
4. Calvin- Benson cycle
5. All proposed answers are endergonic

Answer 1

Examples of endergonic reactions/ processes are All proposed answers are endergonic ( option E is correct).

Endergonic reaction is called when a reaction or process gain energy from outside of the reaction or process. In the other hand, we can says, endergonic reaction is a process or a reaction where energy is absorbed from outside.

Chemotaxis is a endergonic process because chemotaxis can get energy from out site. In chemotaxis, organisms can run through the nutrient or signal. DNA and RNA synthesis is a endergonic reaction and we also knows that RNA synthesis is called transcription. In transcription, phosphate energy are gain from outside of the process. H+ gradient concentration is also a endergonic reaction because here the gradient move through the energy come from out side of the process. Calvin benson cycle is a biogeochemical cycle of carbohydrates biosynthesis cycle and we know it is a endergonic reaction or cycle.

So here, option E is correct.
