Cellular Respiration
Cellular Respiration
The process by which cells break down glucose and other molecules from food in the presence of oxygen to release energy.
Adenosine Triphosphate (ATP)
Adenosine Triphosphate (ATP)
A small molecule (ADP) that gains a phosphate group, becoming ATP, to store energy.
Stage 1 of Cellular Respiration
Stage 1 of Cellular Respiration
The first stage of cellular respiration where glucose is broken down into smaller molecules in the cytoplasm, releasing a small amount of energy.

Study Notes
Photosynthesis Products - Not True
- Some sugar is converted to other compounds like cellulose
- Some sugar is stored in plant cells for later
- Carbon dioxide is released through stomata (This is the incorrect statement)
- Products are used by plants and animals for energy
Extremophiles
- Extremophiles are organisms that survive in harsh environments
- Tardigrades (water bears)- Almost impossible to kill
- Cryptobiotic State - Active State
- Red Flat Bark Beetle Larvae - survives at -150°C
- Thermophiles - thrive in high temperatures, in Yellowstone National Park
- Their vibrant colors help identify them in natural environments
Essential Questions
- What happens during cellular respiration?
- What happens during fermentation?
Cellular Respiration
- The process cells use to get energy from glucose
- Cells continuously break down glucose and other food molecules using oxygen
- Cells release energy in the presence of oxygen
- It is a two stage process
Stage 1 of Cellular Respiration
- Glucose breaks down into smaller molecules and a small amount of energy is released
- The released energy is used to combine ADP with another phosphate to form ATP molecules
- ADP - Adenosine Diphosphate
- ATP - Adenosine Triphosphate
Stage 2 of Cellular Respiration
- Smaller molecules are broken down further in the mitochondria
- Oxygen is required for this stage
- A large amount of energy is released, allowing the cell to function
Photosynthesis and Cellular Respiration
- Cellular respiration and photosynthesis are opposite processes
- Cellular respiration breaks down glucose using oxygen to create energy
- Photosynthesis uses sunlight to create glucose from carbon dioxide and water
- Cellular respiration occurs in the mitochondria of all cells
- Photosynthesis occurs in the chloroplasts of plant cells
- Both processes create energy, but cellular respiration releases carbon dioxide, while photosynthesis releases oxygen
Fermentation
- A process where cells release energy from food without oxygen
- Generates less energy compared to cellular respiration
- Alcohol fermentation occurs in yeast and single-celled organisms producing alcohol, CO2, and a small amount of energy
- Lactic acid fermentation breaks down sugar into energy without oxygen, producing lactic acid as a byproduct (used by bacteria and muscles)
