Electrochemical Gradient

governs the movement of ions into/out of a cell, based on chemical force (ion con gradient) + electrical force (cell’s membrane potential)

Non-Spontaneous Rxn

decrease entropy, requiring a dedicated input of energy

change in Gibbs free energy for a chemical reaction is zero or positive

Photosystem II

first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria.

Co-Transport

When active transport of a solute (uphill) is paired to the diffusion of another solute (downhill)

Ferredoxin

small, mostly acidic, soluble proteins - possess a highly negative redox potential and use their iron-sulfur cluster to act as electron distributors in various metabolic pathways.

Which of the following rxns would decrease the entropy of a system?

Anabolism
