Respiration
• What do you know about respiration?
• What is needed to live?
• Do all organisms require the same thing?
• In pairs, discuss any facts you know in the next two minutes

Respiration“Respiration is breathing in and out”
“Plants photosynthesise but animals respire”
“During respiration, oxygen is produced”
“During respiration, energy is produced”
• Although these comments may sound correct, every single one is wrong
• These are common misconceptions, ‘banana skins’ of the SATs
![Page 5: Respiration L/O ;- To know the equation for respiration](https://reader035.vdocuments.us/reader035/viewer/2022070418/5697c0201a28abf838cd20f8/html5/thumbnails/5.jpg)
Respiration• Respiration takes place in the cells (it is not “breathing in
and out”)
• Respiration is the release of energy (from glucose) in our cells
• Animals and plants respire
• In the light plants respire, but produce the oxygen for this to occur by photosynthesis - the carbon dioxide they produce via respiration is used for photosynthesis
• In the dark plants respire, producing carbon dioxide

Equation
• Remember, in a reaction: reactants products
glucose + oxygen carbon dioxide + water + (energy)
C6H12O6 + 6O2 6CO2 + 6H2O + (energy)
• Respiration is the process of converting glucose to energy, occurring in every cell

• During respiration the gas carbon dioxide is produced - testing for this would show if respiration occurred, and at what rate- The test for carbon dioxide is to use limewater (it goes cloudy)
• Water is also produced
• Energy is also released during respiration. This may be in the form of heat
How could you test for respiration?
HINT – a reaction is usually tested for by measuring how quickly the
reactants are used up or how quickly the products are produced

• You could measure the heat of both the live and dead cultures, and see if carbon dioxide is produced (look for the limewater going cloudy / see if any carbon dioxide bubbles are released)
So how would you test if these dead cells respire?
