1. Human cell organization and protoplasm

Key Concepts & Definitions

  • Cell membrane : A cell membrane is a selectively permeable boundary that controls what enters and leaves the cell and helps maintain internal conditions.
  • Cell membrane proteins : Cell membrane proteins are specialized molecules embedded in the membrane that enable transport, signaling, and cell-to-cell interactions.
  • Endoplasmic reticulum : The endoplasmic reticulum is an internal membrane network that supports synthesis and processing of proteins and lipids.
  • Golgi apparatus : The Golgi apparatus is a membrane organelle that modifies, sorts, and packages proteins and lipids for their final destinations.
  • Mitochondria : Mitochondria are organelles that generate chemical energy by producing ATP through cellular respiration.
