SCIENCE – THE CELL
What are the processes of photosynthesis and respiration and how are they related to one another?
(i.e. The WHO, WHAT, HOW, WHY, WHERE, and WHEN of CELLS “CAPTURING”, “STORING”
AND “USING” ENERGY?)
Cell Energy Notes
INTRODUCTION: The cell is the building block of _________________. Hence, the cell is ALIVE and, since, it’s
alive, it must perform certain processes in order for it to meet the criteria for being alive. It’s got to
_____________, _____________________, ________________________, ________________ _____ ________________,
________________, and _____________________ (i.e. the processes of living things!). AND, in order to meet this
criteria and be able to do the aforementioned processes, it' gotta “capture”, “store”, and “use”
____________________ through the main life process of _______________________! HOW does it do all this…well,
this note-taking organizational chart will be your guide in finding out the answers to this problem…this
problem of HOW DO CELLS “CAPTURE”, “STORE” AND “USE” ENERGY?
IT ALL STARTS WITH WHAT TYPE OF “EATER” YOU ARE AND WHAT KINGDOM YOU

1) ______________ is broken down into ________________, _______________ _______________,
__________ and other substances (e.g. _______________ _______________ – see below!).
2) Not as efficient as _____________________ respiration (i.e. less __________ - ______ less ATP) is
released per glucose molecule).
3) Who does it? ___________ (Fungi) and ______ (Animalia). The _____________ ______________ gas
released in this process causes bread to rise when _____________ is added to bread. It is also the
process that humans go through when they are working out really hard and not enough

____________________________ (OBTAIN energy) is converted from a stored to a useable form (i.e.
burned!) in the MIGHTY ________________________!
Stored energy ( _____________ ) is broken down into the usable
energy molecule ( ________ – adenosine triphosphate ). To get
energy from ATP, the cell removes a __________________ group.
With each removal of a __________________ group, the cell gets
a unit of energy. Therefore, each molecule of ____________ has
_______ energy units in it!
