BI1.1 | Introduction to Basic Biochemistry
This Self-Directed Learning guide introduces the molecular architecture of the living cell — the fundamental unit of life. By the end of this guide, you will be able to describe how a cell is organised at the molecular level, identify its sub-cellular components, and explain the composition and key functions of biological membranes.
Learning Objectives
- Describe the molecular and functional organisation of a typical cell (BI1.1)
- Identify the major sub-cellular components (organelles) and their functions
- Explain the composition of the biological membrane (fluid mosaic model)
- Describe the key functions of biological membranes including selective transport, communication, and compartmentalisation
INSTRUCTIONS
Read each section in order. Bold terms (like this) are key vocabulary — each is defined the first time it appears. Attempt the self-check questions before revealing the answer. Complete the reflection at the end.
