c. ATP and the chemistry of respiration
What have I learned?White boardsAnswer the following:1. What is respiration?2. What raw materials are required for
respiration to take place?3. How do these raw materials enter the cells?4. What are the products of respiration?5. Where in the body does respiration occur?6. Suggest a cell(s) that may have a lot of
mitochondria?
What are we learning today?We are learning to:State what ATP is?State what ATP is used for?Describe the processes involved in aerobic
respiration
Success criteria:ATP and how it supplies energyAerobic respiration in terms of glycolysis and
how many ATP are produced
Adenosine Triphosphate (ATP)ATP is an immediate stored source of energy found in
most cells
ATP has the following structure
Adenosine Pi Pi Pi
1 molecule of adenosine
3 molecules of inorganic phosphate
What is ATP? cont’d
For the energy stored in ATP to be released it has to be broken down to ADP and Pi
releasing energyATP ADP + Pi
high energy build up requiring energy low energy
When energy is stored ADP and Pi are converted back into ATP
Role of ATPATP makes energy available for energy requiring
processes: - muscular contraction - cell division - protein synthesis - transmission of nerve impulsesATP is the link between energy consuming, and
energy releasing reactions
Chemistry of RespirationRespiration is the re-generation of ATP
It is a complex series of biochemical reactions
Aerobic RespirationWhat is involved?
Occurs in presence of oxygenGlycolysis
Means glucose splittingGlucose is split into 2 molecules of pyruvic acidThe pyruvic acid goes through many more enzyme
controlled reactions releasing carbon dioxide and finally producing water
As the reactions proceed ATP is generated38 ATP molecules are produced for every molecule of
glucose
RecapWrite an exit summary to tell me the following:What is ATP?What is ATP used for?How does ATP supply energy?Describe the processes involved in aerobic
respiration:What is glycolysis?What is glucose split in to?How many ATP are produced per glucose
molecule?
