Study Notes
Respiration Overview
- All living organisms depend on energy obtained from food for biological activities.
- Respiration is the process that converts sugars into biochemical energy using oxygen.
- Occurs in diverse organisms: animals, plants, fungi, and bacteria.
- During respiration, energy is released, essential for life-supporting processes.
- Waste products of respiration include carbon dioxide and water.
- Involves gas exchange: oxygen is consumed, and carbon dioxide is expelled.
Plant Respiration
- Plants engage in both respiration and photosynthesis simultaneously during daylight.
- Oxygen and carbon dioxide are utilized in each respective process.
- Photosynthesis requires light, while respiration occurs continuously.
- At night, only respiration takes place, resulting in oxygen intake and carbon dioxide release.
Types of Respiration
- Aerobic Respiration:
- Requires oxygen.
- Predominantly used by most living organisms for energy production.
