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.
