Question

Examples of endergonic reactions/processes are:

a. chemotaxis

b. transcription

c. H+ gradient generation

d. Calvin-Benson Cycle

e. all are endergonic

Answer 1

The above all Examples are endergonic reactions/processes. So option e is correct answer.

When a process or reaction required energy from outside and the process gain or absorb energy from outside, then the reaction is called endergonic reaction/ process. In this reaction, free energy is positive.

In the chemotaxis, outside energy is require for the process of moving organisms in to the nutrients or single. So, chemotaxis is a endergonic process.

In RNA synthesis or transcription process, the phosphate energy is required to complete the process.so transcription is a endergonic reaction and H+ gradient process also required outside energy to flow of H+ ions through gradient. In Calvin benson reaction, energy is required for carbohydrates biosynthesis and energy is gain by Calvin cycle as electron source. So here all examples are gain energy from outside source to complete the process or reaction and free energy is positive. So here option E is right answer.
