To determine which term is energetically favorable among the provided choices, let's analyze each option:

1. Energy Coupling: This refers to the use of energy released from one reaction to drive another reaction. While energy coupling is often favorable, it’s not a standalone term that indicates a favorable condition on its own.

2. Spontaneous Process: This term describes a process that occurs naturally without external input, often resulting in a decrease in free energy (negative Gibbs free energy change). Spontaneous processes are indeed energetically favorable.

3. Endergonic Reaction: This type of reaction requires energy input to proceed (positive Gibbs free energy change), making it non-favorable energetically.

4. Metabolism: This encompasses all chemical reactions in a biological system, and while certain metabolic processes are energetically favorable, this term itself does not specify whether they are favorable or not.

Conclusion

The most appropriate choice indicating something that is energetically favorable is Spontaneous Process. This is because spontaneous processes occur without the need for external energy input, making them energetically favorable overall.
