8.1 READING GUIDE: Energy & Life – ATP!
Use your textbook (pages 226-228) and your lecture notes to answer the following questions.
1) What is ENERGY?
2) What are the three molecular building blocks of ATP? Label the diagram below.
3) Which organelle produces most of the ATP needed by a cell?
4) How is the ATP molecule like a rechargeable battery?
5) How is a molecule of ATP formed from a molecule of ADP?
6) How is ATP different from ADP? Which molecule has more energy?
7) What processes in the CELL need energy from ATP? (list at least 4).
8) List 4 ways in which YOU (your body, not just individual cells) make use of the energy stored in ATP.
(HINT: this is not in the textbook…just think about simple activities that you do that require energy!)
9) Do cells store large amounts of ATP? Why or why not?
10) Compare the energy storing capability of ATP to that of glucose.
For Questions 11-14, complete each statement by writing the correct word or words.
11)

14) Most cells only store enough ATP for
of activity.
15) Define AUTOTROPH:
16) Define HETEROTROPH:
17) What is PHOTOSYNTHESIS?
18) In the table below, place an “X” in the box next to the characteristics that are true of an
autotroph and a heterotrophy.
AUTOTROPH
Directly uses sunlight for energy
An oak tree is an example
A mushroom is an example
Makes its own food
Consumes other living things to get energy
Is capable of photosynthesis
A cheetah is an example
HETEROTROPH
