Study Notes
Respiration in Organisms
- Organisms respire to obtain energy from food
- Breathing involves taking in oxygen-rich air and releasing carbon dioxide-rich air
- Cellular respiration is the process of breaking down food in cells to release energy
- Aerobic respiration uses oxygen to break down glucose, releasing carbon dioxide and water
- Anaerobic respiration occurs without oxygen, and breaks down glucose into other substances
- Yeast respires anaerobically, producing alcohol and carbon dioxide
- Muscle cells can respire anaerobically during intense exercise, producing lactic acid
- Breathing rate varies depending on activity level and oxygen demand
Breathing Rate
- Breathing rate is the number of breaths per minute
- Breathing rate increases with physical activity
- Breathing rate slows down at rest
- Individuals have different normal breathing rates
Breathing Mechanism
- Breathing involves inhalation (taking in air) and exhalation (releasing air)
- Inhalation: Diaphragm contracts and ribs move upward and outward, expanding chest cavity
- Exhalation: Diaphragm relaxes and ribs move downward and inward, reducing chest cavity
- Air moves in and out because of changing size of the chest cavity
Structures and Processes in Different Organisms
- Different organisms have different structures for gas exchange:
- Insects have tracheae (tubes) for gas exchange
- Fish use gills to absorb dissolved oxygen from water
- Earthworms exchange gases through their skin
- Plants exchange gases through stomata
Respiration in Water
- Organisms in water have adaptations for respiration in aquatic environments
- Fish use gills to extract dissolved oxygen from water
- Some organisms can breathe air and water
- Whales and dolphins surface to breathe air.
Respiration in Plants
- Plants also respire to release energy from food using oxygen
- Plants take in CO2 and release O2 during the day
- Photosynthesis occurs during the day and helps plants produce foods
- Respiration occurs at night or when there is no sunlight
