examples of cellular respiration grade 10

📚 Quick Study Guide

• 🍎 What it is: Cellular respiration is the process by which organisms convert glucose (sugar) into energy (ATP) that cells can use.
• 💨 Reactants: The main reactants are glucose ($C_6H_{12}O_6$) and oxygen ($O_2$).
• ⚡️ Products: The main products are carbon dioxide ($CO_2$), water ($H_2O$), and ATP (energy).
• 🔄 Equation: The overall equation is: $C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + ATP$
• ☀️ Stages: There are four main stages: glycolysis, pyruvate oxidation, the Krebs cycle (also called the citric acid cycle), and oxidative phosphorylation (electron transport chain and chemiosmosis).
• 📍 Location: Glycolysis occurs in the cytoplasm, while the other stages occur in the mitochondria (in eukaryotes).
• 💡 ATP Production: Oxidative phosphorylation produces the most ATP.
