Honors Packet 4: Cell Energy
Bio.4.2 Analyze the relationships between biochemical processes and energy use in the
cell.
 Bio.4.2.1 Analyze photosynthesis and cellular respiration in terms of how energy is stored,
released, and transferred within and between these systems.

Bio 4.2.2 Explain ways that organisms use released energy for maintaining homeostasis
(active transport).
Bio.1.1 Understand the relationship between the structures and functions of cells and their
organelles.
 Bio.1.1.1 Summarize the structure and function of organelles in eukaryotic cells (including
the nucleus, plasma membrane, cell wall, mitochondria, vacuoles, chloroplasts, and
ribosomes) and ways that these organelles interact with each other to perform the function
of the cell.

Photosynthesis Notes
1. Definition/Goal – _______________________________________________________
2. Equation –
(carbon dioxide)
(water)
(glucose)
(oxygen)

3. Photosynthesis consists of 2 steps: a light dependent reaction and light independent
reaction or Calvin cycle:
sunlight
Light
Dependent
Reaction
ATP
Light
Independent
Reaction
(Calvin or
Dark cycle)
C6H12O6
a. Goal of the Light Dependent reaction: ______________________________________
b. Goal of the Light Independent reaction: _____________________________________
4. Location - _______________________________________
5. Chloroplast Structure:
6. How do plants absorb light?
Notice the stacks inside of the chloroplast. These stacks absorb sunlight. This
arrangement increases the amount of _____________________________________ to
absorb as much sunlight as possible.
Plants contain _________________________ that _______________ some wavelengths
of light and ________________ others. For example, if a plant appears red, the plant
________________ this color. ______________________ is one of the most abundant
pigments in a plant which absorbs the red and blue colors of the spectrum and reflects
________________ which is what makes plants appear green. The light plants absorb is
used to undergo __________________________.

Cellular Respiration Notes
1. Definition/Goal – _________________________________________________________
Analogy:
glucose is like a _____________, ATP is like _________
2. Location: _______________________________
Notice the highly folded inner membrane. These folds increase the
amount of __________________________ so lots of ATP can be
made.
3. 2 Types Cellular Respiration:
a.
(Best Option) ____________________________ Respiration

If ___________________ is present, the cell may continue ATP production by going
through aerobic respiration. Aerobic Respiration is most commonly used and preferred
because much more ATP can be produced.
The equation for aerobic respiration is:
_____________ + ______________  ___________ + ___________ + _________ATP
Cellular Respiration has 3 steps: Glycolysis, Kreb’s Cycle and the Electron Transport Chain (ETC)
Can occur with
or without
oxygen
C6H12O6
Glycolysis
Must have oxygen present in
last 2 steps
Kreb’s
Cycle
ETC

b.
(Other option) _____________________________ Respiration

When __________ is NOT present, also called ___________________________.

2 Types of Fermentation:
1. ________________________ Fermentation occurs in yeast.

Equation: ____________ ____________ + ________ + ____ ATP

These ingredients are used to make many foods:
o
In _______________, yeast releases _____________________ - which is
what adds holes or air bubbles to your bread
o
The alcohol produced by yeast is utilized in ________________.
2. Lactic Acid Fermentation - occurs in ______________________ cells when they
run out of _______________.

Equation: ______________ ____________________ + _____ ATP

When you are exercising really hard your muscles use up their ATP and oxygen
sot the muscle cells begin to produce ATP through lactic acid fermentation.

_________________ ___________________ is the product, which builds up in
your muscles. This can create a painful burning sensation which you may feel
during intense exercise.
Structure of ATP & ADP:
Energy is stored in the bond between the ___________________________, when the bonds break
energy is ________________________ to power chemical reactions, your cells and ultimately your body.
The goal of cellular respiration is to take ADP and create ATP by adding on a _______________.
