ملخص الدرس

This lesson explores the biochemical operations of living cells, focusing on aerobic cellular respiration in mitochondria and the mechanisms of cellular homeostasis. It explains the chemical reaction converting glucose and oxygen into ATP energy, water, and carbon dioxide, and details membrane transport mechanisms: diffusion, osmosis, and selective permeability.

هتتعلم إيه فى الدرس ده

• Cellular respiration in mitochondria breaks down glucose with oxygen to yield ATP energy.
• The respiration equation: $\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{ATP}$.
• Homeostasis is the maintenance of stable internal conditions within the cell.
• Passive transport occurs via diffusion (solutes) and osmosis (water) across the selectively permeable membrane.
