Cellular Processes

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.

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

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

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

Diffusion is the tendency of molecules to spread into an available space. The diffusion of substances across a membrane is called passive transport.

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.
