Biological Membranes

Biological Membranes

Watch this webinar to learn about the foundations of biological membranes, which is a key area of MCAT cell biology. You will learn about the components of biological membranes, how to predict membrane fluidity and permeability, and how to differentiate between gram-negative and gram-positive bacteria based on their membranes.

At a glance


Essential skills

  • Predict membrane fluidity and permeability

  • Differentiate between gram-positive and gram-negative bacteria based on membrane


Knowledge Fundamentals

  • The components of biological membranes for eukaryotes and prokaryotes

  • How certain biomolecules can affect membrane fluidity and movement


On the MCAT

  • A basic understanding of biological membranes starts with memorizing biomolecules like phospholipids

  • A deeper understanding of membranes requires some organic chemistry and microbiology


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
