ATP, cellular, and chemical enery

Question 1

energy overview

Answer 1

• Food = chemical energy found in bonds of carbs/proteins/fats
• Cellular Energy = ATP which comes from breakdown of chemical energy (glucose)
• Why do our cells need energy?
  
  • To build complex molecules
  • Active transport in nerve cells
  • Contract+relax muscles in body
  • Move things around cells
  • Secrete out molecules
• Consists of adenine, ribose, three phosphate groups
• Lots of energy released when broken
• High energy bond between 2nd + last phosphate group broken → energy released + ADP formed
• Energy from food used to add phosphate group back to ADP, forming ATP and storing energy again
