Biochemistry Notes: Membrane Energetics

Membrane Energetics: Transport & Gradients (Complete Notes)

Master the thermodynamics of how cells build barriers and power the movement of molecules against gradients.

📂 Topics Covered:

1. Membrane Assembly: How the Hydrophobic Effect drives spontaneous bilayer formation ($\Delta G < 0$ due to entropy).
2. Passive vs. Active Transport: The thermodynamic difference between "downhill" diffusion and "uphill" work.
3. Energy Coupling: How ATP hydrolysis powers Primary Active Transport (e.g., Na-K Pump).
4. Secondary Active Transport: Harnessing electrochemical gradients (e.g., Lactose Permease).
5. Proton-Motive Force: The "Interconvertible Currency" used for ATP synthesis and motility.

✅ Perfect for: NEET/CSIR-NET aspirants needing clarity on membrane physiology and bioenergetics.
