Cell Biology
- Overall Cell anatomy/physiology and mechanisms
- The Cell - A good basic introduction into membrane, ER, et cetera. (good printable pictures-in color) (Internet link) (01)
- Cell Biology Animations - This Internet site shows excellent animations on all aspects of a living cell's mechanisms. A definite place to visit. (Internet Link) (02)
- Cell membrane
- Fluid mosiac cell membrane. The bilipid layer cell membrane with its proteins is moving but so slightly. This animation shows the related structures.(01)
- ATPase ATP driven active transport pumps are important to move solutes against their concentration gradients. This animation illustrates how this may occur. (02)
- Structure
- Channels regulate. Protein based channels regulate the movements of specific solutes through a membrane. Two types, gated and non gated channels are shown in this animation. (03)
- Structure of a cell membrane showing why it is only two layers of a lipid. (04)
- Vesicular transport
- Endocytosis (15)
- Endocytosis and exocyotosis (16)
- Phagocytosis
- This old animation was found somewhere on the Internet. It does show how a wbc will engulf a foreign substance if stimulated or activated. (09)
- Active Transport
- Sodium-Potassium pump. This good visual shows the basic details of the mechanism. [turn DOWN your speakers before you open this] (04)
- The sodium-potassium pump is the most studied of all active ransport mechanisms. This shows one artist's view of the channel protein involved (11)
- This explanation of the Na-K pump includes audio to explain the concentration gradient this pump creates and maintains as a trait of life. (13)
- Membrane depolarization. All living membranes have channels to regulate. This animation shows how Sodium and Potassium are allowed to move through these gates producing concentration gradients and thus charges membranes. (05)
- Diffusion
- Simple diffusion. Simple diffusion is the reason for all types of passive transport exist such as osmosis. (06)
- This animation shows diffusion through a membrane. (12)
- Osmosis
- Cellular transport. A good animation showing diffusion/osmosis, passive transport and active transport mechanisms. (14)
- Electrolytes - Intracellular and Extracellular
- Visualizing the different electrolytes between the intracellular and extracellular can be difficult. This link shows the differences.
- Protein Synthesis
- Protein synthesis - All on one sheet is a general summary of the entire process. (02)
- Protein synthesis. This animation requires you to interact with it as a protein is constructed. (03)
- Protein synthesis. An animation with some printable photos are used to explain the process. This shows the amino acids that combine with each triplet anticodon of a t-RNA (transfer RNA) (04)
- Transcription Animation (05)
- Transcription Animation (06)
- Translation. Animation (07)
- Translation. A detailed animation (08)
- Translation Animation (09)
- Translation Animation (10)
- Translation A detailed view of the mRNA is included in this animation. (11)
- Printable Sketches of Protein Synthesis This page will have links to printable colorful images that explain the basics of protein synthesis. (12)
- Cell Metabolism
- Mitochondral metabolism. This animation shows all three reaction sequences. A good place to start. (01)
- The citric acid cycle. (Kreb's cycle) (03)
- The electron transport chain. Basic animations with explanative text summarizes this process. (04)
- The electron transport chain or hydrogren transport system uses hydrogen from glucose as the energy source. (05)
- The electron transport chain. This process uses oxidative phophorlation to store energy into ATP. Animation without audio. (06)
- Cancer
- Cancer is an ailment with many different causes and thus many different treatments. This animation is from the PBS series - NOVA.
- Cancer can be shown in many sequences. The following are two variations by the same artist or animator:
- Cancer within a tissue
- Breast cancer within the same tissue (above)
- Organelles
- Golgi body.
- Lysosome and phagocytosis
- DNA / RNA
- The duplication of DNA allows for identical copies of cells as a tissue grows and repairs.
