New Video Posted: Organelles and Membranes - how much membrane is in a cell?

This is an interesting question: "How much membrane is in a cell?".

In this video, I use a football and some sheets of material to explore how much membrane we have in a cell and which organelles have the most membrane.

This was a fun video to make, and I got some very odd looks from passing dog walkers.

New Video Posted: Organelles - Understanding Vesicular Transport

Cells have organelles, and they need to transport the correct molecules to those organelles — if they don't, the cell will not function correctly and will die. 

The cell has three ways of moving molecules around:

  1. Vesicular transport
  2. Gated transport
  3. Transmembrane transport
This video also looks at vesicular transport, which uses small membrane-bound sacs to move proteins, lipids, and other molecules throughout the cell.

The video introduces the concepts of Endocytosis and Exocytosis - including Phagocytosis, Pinocytosis and Receptor-Mediated Endocytosis, along with Constitutive and Regulated Pathways.

New Video Posted: An introduction to cell organelles - why do cells have organelles?

In this video, I look at why cells have organelles - my answer might surprise you.

I also examine the different organelles, discuss how proteins are targeted to these organelles, and describe the mechanisms used to get proteins across membranes.

New Video Posted: Understanding Microscopy: Debunking Misconceptions in Cellular Biology

This was a fun video to make!

In this video, I use bagels to explain how some common misconceptions about the function and shape of organelles came about. I also explore, using images of horses, how we have not fully appreciated the dynamic structure of the cell and vesicle trafficking.
