Cellular Processes
Information on cellular processes of the body including cellular respiration and DNA transcription.
Diffusion and Passive Transport
Diffusion is the tendency of molecules to spread into an available space. The diffusion of substances across a membrane is called passive transport.

Cellular Respiration
Cellular respiration is a process by which cells harvest the energy stored in food. Glycolysis, the citric acid cycle, and electron transport are the three main processes of cellular respiration.
