Study Notes

Cellular Respiration

All organisms are composed of cells, the smallest structural and functional units.
Cells perform various functions, including nutrition, transport, excretion, and reproduction, all requiring energy.
Food stores energy released during respiration.
Organisms respire to obtain energy from food.
During respiration, organisms breathe in oxygen-rich air and breathe out carbon dioxide-rich air.
Air is transported to cells where oxygen helps break down food.
Cellular respiration is the process of food breakdown in cells, releasing energy.
This process occurs in all cells.
Aerobic respiration uses oxygen; glucose is broken down into carbon dioxide, water, and energy.
Anaerobic respiration occurs without oxygen; glucose is broken down into alcohol, carbon dioxide, and energy.
Some organisms, like yeast, are anaerobes and survive without oxygen through anaerobic respiration.
