Summary Introduction

To determine: How the “second law of thermodynamics” explains the diffusion of a substance across a membrane?

Introduction: The second law of thermodynamics states that “Total energy cannot decrease over time in an isolated system”. An isolated system is a system where there is no exchange of matter or energy. Diffusion of a substance across a membrane occurs based on the concentration gradient.

MAKE CONNECTIONS Explain why the set of forces driving ionmovement across the plasma membrane of a cell is described as anelectrochemical (electrical and chemical) gradient (see Concept 7.4).
WHAT IF? Some membrane proteins diffuse faster in the plasma membrane when the cytoskeleton or the extracellular matrix is artificially removed than when cells are unperturbed. Explain why.
