Assemblies of Molecules, Cells, and Groups of Cells

Assemblies of Molecules, Cells, and Groups of Cells

by Kevin Ahern, PhD, Georgina Cornwall, PhD

This course covers the material of content category 2A of the official MCAT exam content outline.

From the smallest to the largest order, biological systems organize themselves into collections of molecules that together make up the structures that form cells. These cells continue to organize themselves into tissues and later organs, making up entire multicellular and multisystemic organisms. These arrangements of nigh unfathomable complexity represent a continuous challenge to those dedicated to the study of molecular and cellular biology.

In this course, the student will be given an overview of the assemblies of different molecules, cells, and tissues. For optimal comprehension, the student should be familiar with the basic concepts of college-grade biology and chemistry.

Great lecture.
By Mariana . on 15. January 2024 for Passive Transport – Transport Across Cell Membranes

Easy to understand.I like how she uses examples to illustrate passive vs. active transport.

By Mariana . on 15. January 2024 for Lysosomes

Amazing lecture, Dr. Georgina lessons are by far the best I've had in citology. Very clear and straight forward, perfect for the Mcat. Thank you!

Excellent lecture.
By Mariana . on 14. December 2023 for Endoplasmic Reticulum and Golgi Apparatus

The most important part of this lecture in my opinion is the analogies that Dr. Georgina offers. It really help us to understand for example when she associated the Golgi Complex with a Fedex facility, or when she connects the fact that liver cells have more SER since one of its important functions is detoxification.

good lecture

she is doing very well in explaining the topics and precise.
