Homework Quiz
Describe the structure of ATP
Describe the ATP cycle
Homework Quiz:
Write the answers down that you have on your homework
for the specific questions.
When you finish please turn it into the tray.
If you do not have some answers on homework you
CANNOT answer on quiz!!
I. Energy and living organisms
A. Photosynthesis- light energy (sunlight) is converted
to chemical energy (glucose)
1. Autotrophs- use sunlight to make own energy-food
2. Heterotrophs- organisms that must get energy from food
instead of directly from sunlight (must eat)
B. Living things store energy in compounds
such as ATP and ADP
Draw an
1. ATP consists of:
a. adenine
b. ribose (a 5-carbon sugar)
c. 3 phosphate groups
ATP
molecule
on your
notesheet!
2. Energy stored in bonds between phosphate groups,
break bonds release energy
* The phosphate “tails” are unstable due to their
negative charges
* Negative phosphate groups want to repel each
other
a. ATP breaks off a P, releases energy, becomes
ADP
3. ATP – P -----→ ADP (adenosine diphosphate)
Released
ENERGY
After the ATP loses its phosphate group,
its becomes ADP, then it gets a new
phosphate group and is ATP again!
a. ADP then gets another P added to it
(recharged) and is ready to be used again
Adenosine
Diphosphate
Partially
charged
battery
Energy
Adenosine Triphosphate
Fully
charged
battery
C. How ATP is used
1. During Active transport
2. move organelles inside the cell along microtubules
(like a train track)
3. Storing and transferring small amounts of energy
a. One molecule of glucose can store 90 X the
amount of energy of one ATP
**energy currency example**

I. Cellular Respiration
A. Cellular Respiration is the process that
releases energy by breaking down glucose
1. Use oxygen to get energy from glucose
and form ATP molecules
2. C6H12O6 + 6O2 --> 6CO2 + 6H2O+ ATP
Glucose + oxygen →carbon dioxide + water +
energy
3. EVERY living thing does cellular respiration

III. Breaking down glucose in the absence of
Oxygen
A. Fermentation – releases energy from
food molecules in the absence of oxygen
1. Anaerobic- not using oxygen
2. Cells convert NADH back into NAD+
3. Glycolysis repeats itself (a lot)
B. 2 types of fermentation:
1. Lactic Acid fermentationa. Pyruvic acid that accumulates as a result of
glycolysis is converted to lactic acid
b. Produced by muscles during exercise
when the body cannot supply enough oxygen
1.) Build up of lactic acid causes painful burning in
muscles
2. Alcoholic- Yeasts use; produce small amount
of ATP
pyruvic acid + NADH→ alcohol +CO2+ NAD+
a. Yeast in dough runs out of oxygen, does
fermentation, CO2 causes bubbles in bread
• History: Louis Pasteur studied fermentation
to help the French wine industry. He
discovered “the Pasteur Effect” – When
yeast and grape juice are sealed into a
fermentation vessel, the yeast grows until all
the oxygen is used up. At this point the
yeast switches to fermentation and alcohol is
produced. Sugar is used up very quickly by
the yeast during fermentation since little
energy can be released from each glucose
molecule without O2 (2ATP).
IV. Energy and Exercise
A.To obtain energy the body uses energy already in muscles,
ATP made by lactic acid fermentation, and ATP made by
cellular respiration
B. Quick Energy- lots of energy fast. Your body will first use
the energy stored in muscles, but then have to switch to
lactic acid fermentation (90 seconds or less)
1. Oxygen Debt- the only way to get rid of lactic acid is to
get extra oxygen into your body-deep breaths
C. Long term energy- Over 90 seconds requires cellular
respiration to generate a continuous supply of ATP.
1. For 15-20 minutes your body breaks down glycogen
(carbohydrates), after this your body starts to breakdown
fats

Today 11/27/2013:
Investigate Muscle Fatigue
Analyze Data
Fermentation Quiz Next Week Wednesday!!
NO Homework!!
Have a safe and fun Thanksgiving
Muscle Fatigue:
Muscle cells often need a very large
supply of ATP for rapid bursts of activity.
For short, quick bursts of energy, the body
uses ATP already in muscles as well as
ATP made by lactic acid fermentation
When lactic acid fermentation happens the
lactic acid builds up in muscle cells and
causes painful burning.
Investigating muscle fatigue:

•
Hold clothespin in hand you write with
(dominant hand). Squeeze as hard as you can
and as many times as you can in 30 sec. (Hold
clothespin between thumb and index finger, all
other fingers straight out! )
Record this number in the chart below.
(Squeeze as quickly and as completely as
possible)
Repeat this process 9 more times for a total of
10. Do not rest your hand between trials.
Repeat steps 1 and 2 for non-dominant hand.
