Cellular Respiration and Energy Production
This section details the relationship between photosynthesis vs cellular respiration in plants and the locations where these processes occur within cells.
Definition: Cellular respiration is the process of breaking down glucose to produce ATP, occurring in all living cells.
Highlight: While photosynthesis occurs only in plant chloroplasts, cellular respiration takes place in all cells' mitochondria (except bacteria, where it occurs in the cytoplasm).
Example: The cellular respiration equation is: C6H₁₂O6 + 6O₂ → 6CO₂ + 6H₂O + 36ATP
Vocabulary: Mitochondria are the cellular organelles responsible for energy production through cellular respiration.

Fermentation and Anaerobic Respiration
This page explores what is fermentation and its role in cellular energy production when oxygen is unavailable.
Definition: Anaerobic respiration, or fermentation, is cellular respiration without oxygen, producing only 2 ATP compared to 36 ATP in aerobic respiration.
Highlight: Fermentation occurs in two main types: lactic acid fermentation in muscle cells and alcohol fermentation in bacteria and yeast.
Example: Lactic acid fermentation equation: Glucose → 2 lactic acid + 2 ATP Alcohol fermentation equation: Glucose → 2 ethyl alcohol + 2CO₂ + 2ATP
Vocabulary: Glycolysis is the first step of cellular respiration that doesn't require oxygen and occurs before fermentation or the Krebs cycle.

ATP and Photosynthesis
The foundation of cell energy revolves around ATP (Adenosine Triphosphate) production and utilization. This page explores the fundamental processes of cellular energy production and photosynthesis.
Definition: ATP (Adenosine Triphosphate) is the primary energy currency of cells, consisting of adenosine and three phosphate groups.
Vocabulary: Photosynthesis is the process where plants convert sunlight into chemical energy, producing glucose and oxygen from carbon dioxide and water.
Example: The photosynthesis equation can be written as: 6CO₂ + 6H₂O → C6H₁₂O6 + 6O₂
Highlight: The conversion from solar energy to chemical energy during photosynthesis is a crucial process that sustains life on Earth.
