Endergonic

 Endergonic means a reaction that requires energy to happen.

In simple terms:

• "Endo-" means in

• "Ergon" means energy or work

• So, endergonic = energy goes in

Example:

• Photosynthesis is an endergonic process. Plants absorb sunlight energy to make glucose from carbon dioxide and water.

• You have to put energy in for the reaction to work.

Key point:

• Endergonic reactions are not spontaneous.

• They have a positive ΔG (change in free energy), meaning the products have more energy than the reactants.

✅ So, if a reaction needs energy to happen = endergonic
