Transcript of Chemical Energy and ATP Energy in glucose & lipids is converted into ATP –A–Adenosine...
Chemical Energy and ATP
• Energy in glucose & lipids is converted into ATP– Adenosine triphosphate– Energy for work is stored in ATP bonds
Energy and ATP
• Energy in glucose & lipids is converted into ATP– Adenosine triphosphate– Energy for work is stored in ATP bonds
• Energy released when 3rd phosphate is broken off– 3rd bond unstable…easily broken– ADP left over

Energy and ATP
• Energy in glucose & lipids is converted into ATP– Adenosine triphosphate– Energy for work is stored in ATP bonds
• Energy released when 3rd phosphate is broken off– 3rd bond unstable…easily broken– ADP left over
• ATP recreated with the addition of another phosphate group

Digestion• Purpose: Break food into useable molecules to create ATP
• High calorie foods will produce more ATP molecules

Digestion• Purpose: Break food into useable molecules to create ATP
• High calorie foods will produce more ATP molecules
• Carbohydrates commonly used to make ATP
– 1 glucose = 36 ATP
36 ATP
Digestion• Purpose: Break food into useable molecules to create ATP
• High calorie foods will produce more ATP molecules
• Carbohydrates commonly used to make ATP
– 1 glucose = 36 ATP
• Lipids
– 1 triglyceride = 146 ATP
146 ATP

• Proteins less likely to be broken into ATP
– Amino acids are needed for other processes
Energy on Earth• Most life relies on
sunlight directly or indirectly– Directly: Plants– Indirectly: Animals
• Exceptions: Chemotrophs– Hydrothermal vents
release chemicals called sulfides
– Unique bacteria feed on the sulfides to make ATP (chemosynthesis)
sulfidessulfides

1) Where is the energy of ATP stored?
2) How is ADP and ATP different?
3) Which process connects ADP and P to make ATP?
4) Which process breaks ATP to make ADP and P?
5) What’s the purpose of digestion?
6) How much ATP is created by a molecule of glucose?
7) How is chemosynthesis and photosynthesis similar? Different?
