BIOLOGY RULE COPIED!

Cell Respiration

C6H12O6 + 6O2
→ 6CO2 + 6H2O + ATP
Concept: Glucose and Oxygen break down to create Carbon Dioxide, Water, and Energy.

Cellular Respiration Guide 🌿

C₆H₁₂O₆
Glucose

The primary fuel source. A high-energy sugar molecule broken down for energy.

O₂
Oxygen

The essential electron acceptor required for aerobic respiration to occur.

CO₂
Carbon Dioxide

A waste product released during the Krebs cycle as carbon atoms are stripped.

H₂O
Water

Formed at the end of the electron transport chain when oxygen picks up protons.

ATP
Energy (ATP)

Adenosine Triphosphate: The "energy currency" of the cell used for work.

G
Glycolysis

The first step in the cytoplasm where glucose is split into two pyruvate molecules.

M
Mitochondria

The "powerhouse" organelle where the Krebs cycle and ETC take place.

e⁻
Electrons

Carried by NADH and FADH₂ to power the production of ATP.

Σ
Enzymes

Biological catalysts that speed up the complex reactions in the respiration pathway.

The 3 Stages of Energy Production

⚡

STAGE 01 | GLYCOLYSIS

Happens in the Cytosol. One Glucose molecule is broken down into two Pyruvate molecules. This step doesn't need oxygen and produces a small amount of ATP.

STAGE 02 | KREBS CYCLE

Takes place inside the Mitochondrial Matrix. Pyruvate is further processed to release CO2 and high-energy electrons for the final stage.

STAGE 03 | ETC

The grand finale on the Inner Membrane. Oxygen combines with electrons and hydrogen to make water, releasing a massive burst of ATP energy!

"Did you know? From one single molecule of Glucose, your body can generate up to 36-38 molecules of ATP!"
