Respiration
Bayani Gaba-gaba
Everything a living thing does, from a heartbeat to a growing root, costs energy. That energy does not come from nowhere: it is released inside cells by a process called respiration, which happens in every living cell every second of your life.
In this lesson you will learn the many jobs that energy is used for in living organisms, and you will investigate how temperature changes the rate of respiration using yeast. By the end you should be able to list what energy powers and explain why warming a cell speeds respiration up, but only up to a point.
Manufura
- [Core] State the uses of energy in living organisms, including: muscle contraction, protein synthesis, cell division, growth and the maintenance of a constant body temperature
- [Core] Describe aerobic respiration as the chemical reactions in cells that use oxygen to break down nutrient molecules to release energy
- [Core] State the word equation for aerobic respiration as: glucose + oxygen → carbon dioxide + water
- [Supplement] State the balanced symbol equation for aerobic respiration as: C H O + 6O → 6CO + 6H O 6 12 6 2 2 2
