Chapter 5 A. The Movement of Substances Across Cell Membranes Learning Objectives: 1. Principles of membrane transport 2. Passive transport and active transport 3. Two main classes of membrane transport proteins: Carriers and Channels; 4. The ion transport systems; 5. Endocytosis and Phagocytosis: cellular uptake of macromolecules and particles
Similarity of regulation between eukaryotes and prokaryote 1. Principles are the same: signals, activators and repressors, recruitment and allostery, cooperative binding 2. Expression of a gene can be regulated at the similar steps, and the initiation of transcription is the most pervasively regulated step
