• CELL RESPIRATION is a process in living cells. During respiration, sugar molecules are broken down with oxygen. The sugar is broken into carbon dioxide molecules and water molecules… ENERGY is released from the sugar during this process.

•CELL RESPIRATION is a process in living cells. During respiration, sugar molecules are broken down with oxygen. The sugar is broken into carbon dioxide molecules and water molecules… ENERGY is released from the sugar during this process.
• This energy from sugar is used to form
ATP. ATP stores the energy released by the sugar. Burning 1 molecule of glucose sugar can give enough energy to make 38 molecules of
ATP
Why do cells burn Glucose?To make ATP
Gills allow oxygen to enter blood. Why?
TO BURN SUGAR.C6 H12 O6 + O2 CO2 + H2O + ENERGY
Gills also release Carbon Dioxide from the burned sugar back to the water
This prevents a build-up of CO2 in the body. CO2 is the waste product of respiration
LUNGS allow OXYGEN to enter the blood. WHY??
To burn Glucose sugar
BUT… why burn sugar anyways?
• In a living cell… The energy from the burning of glucose sugar is used to force ADP to combine with a third phosphate.
• The energy released by the sugar is now
stored in the molecule of ATP. Formed by combining ADP and P
ATP is THE MOLECULE which cells use for energy
ENERGY FLOW GOES LIKE THIS
• Sun Glucose sugar ATP -
• ENERGY From ATP is released to the cell as heat or movement etc…

•ALL LIVING CELLS USE ATP for energy
DO PLANTS BURN SUGAR ?
•YES !!
Plants make sugar so they can burn that sugar later on
Do animals respirate sugar?( burn sugar with oxygen ? )
•YES
