Respiration
Overview
Every living cell needs a continuous supply of energy, and respiration is the process that provides it. Whether you are sprinting or sleeping, your cells are breaking down glucose to release the ATP that powers everything from muscle contraction to nerve impulses.
In this lesson you will compare aerobic and anaerobic respiration, learn their equations, understand why ATP matters, and explore a classic practical for detecting the products of respiration in living organisms.
Objectives
- Understand how the process of respiration produces ATP in living organisms
- Know that ATP provides energy for cells
- Describe the differences between aerobic and anaerobic respiration
- Know the word equation and the balanced chemical symbol equation for aerobic respiration in living organisms
- Know the word equation for anaerobic respiration in plants and in animals
- Investigate the evolution of carbon dioxide and heat from respiring seeds or other suitable living organisms
