Cellular Processes

Information on cellular processes of the body including cellular respiration and DNA transcription.

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.

Citric Acid Cycle
The citric acid cycle is a stage in cellular respiration that helps to harvest the energy stored in carbohydrates, proteins, and fats.

Cellular Respiration Quiz
Take the Cellular Respiration Quiz and find out how much you know about cellular respiration.

10 Steps of Glycolysis
In glycolysis, glucose is split into two molecules of a three-carbon sugar.

DNA Transcription
DNA transcription is a process that involves the transcribing of genetic information from DNA to RNA.

Protein Synthesis - Translation
Protein synthesis is accomplished through a process called translation. In translation, RNA and ribosomes work together to produce proteins.

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.

How Steroid Hormones Work
Become familiar with how steroid hormones work in the body to produce proteins.

Apoptosis, or programmed cell death, involves a controlled sequence of steps in which cells signal self termination.
