2.1 Energy and ATP

HideShow resource information
Name 8 froms of energy...
1) Light, 2) Heat 3) Sound 4) Electrical 5) Magnetic 6) Mechanical 7) Chemical 8) Atomic Energy
1 of 5
What are the 3 stages in which energy flows through living systems?
1) Light energy from sun converted by plants into chemical energy during photosynthesis 2) Chemical energy in the form of organic molecules is converted to ATP during respiration in cells. 3) ATP is used by cells to perform useful work.
2 of 5
How many phosphate groups does ATP have?
3
3 of 5
Are the bonds between the phosphate groups in ATP stable or unstable and why is this good?
They are unstable, this is good as they have low activation energy, so are easily broken.
4 of 5
What is used to convert ATP to ADP? What is this reaction called?
Water, and Hydrolysis.
