PPT-Cell Structures, Functions and Transport

Types of Cells Prokaryotic cells Eukaryotic cells Prokaryotic cells Simplest cells No membranes around their nuclear material DNA and RNA genetic material Prokaryotes include bacteria and some pond scum.

Active Transport Driven by ATP Hydrolysis. The net flow of molecules by facilitated diffusion, through either carrier proteins or channel proteins, is always energetically downhill in the direction determined by electrochemical gradients across the membrane. .
