Forms of stored energy in cells

Forms of stored energy in cells. Electrochemical gradients. Covalent bonds (ATP). Reducing power (NADH). During photosynthesis, respiration and glycolysis these forms of energy are converted from one to another. How is H+ EC gradient generated?.

Passive vs. active transport

Passive vs. active transport. Passive transport is simply transport down an electrochemical gradient until equilibrium is reached Active transport results in accumulation of solute beyond equilibrium, the unfavorable thermodynamics is driven by ATP hydrolysis. Passive vs. facilitated diffusion.
