National 5 Biology Respiration 2 What is ATP

National 5 Biology Respiration 2. What is ATP?

What have I learned? �White boards �Answer 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? Success criteria: �ATP and how it supplies energy

Adenosine Triphosphate (ATP) �ATP is an immediate stored source of energy found in most cells �ATP has the following structure Adenosine 1 molecule of adenosine Pi Pi Pi 3 molecules of inorganic phosphate

What is ATP? �For the energy stored in ATP to be released it has to be broken down to ADP and Pi releasing energy ATP high energy build up requiring energy ADP + Pi low energy �When energy is stored ADP and Pi are converted back into ATP

Role of ATP �ATP makes energy available for energy requiring processes: � - muscular contraction � - cell division � - protein synthesis � - transmission of nerve impulses �ATP is the link between energy consuming, and energy releasing reactions

Chemistry of Respiration �Respiration is the re-generation of ATP �It is a complex series of biochemical reactions

Role of ATP Summary Carbon dioxide + water RESPIRATION Glucose + oxygen Amino acids ATP energy ENERGY TRANSFER ADP + Pi energy WORK Protein

Experiment �Follow the instructions on the experiment card

Experiment conclusions �Which solution supplied the most energy to the muscle? �Is ATP a protein? �Explain your answer to the above

Recap Write an exit summary to tell me the following: �What is ATP? �What is ATP used for? �How does ATP supply energy?
