Slide 5
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!!
Slide 6
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)
Slide 7
B. Living things store energy in compounds such as ATP and ADP
1. ATP consists of: a. adenine b. ribose (a 5-carbon sugar) c. 3
phosphate groups Draw an ATP molecule on your notesheet!
Slide 8
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)
Slide 9
a. ADP then gets another P added to it (recharged) and is ready
to be used again Energy Partially charged battery Fully charged
battery Adenosine Diphosphate Adenosine Triphosphate Released
ENERGY After the ATP loses its phosphate group, its becomes ADP,
then it gets a new phosphate group and is ATP again!
Slide 10
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**

Slide 44
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)
Slide 45
B. 2 types of fermentation: 1. Lactic Acid fermentation- a.
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
Slide 46
2. Alcoholic- Yeasts use; produce small amount of ATP pyruvic
acid + NADH alcohol +CO 2 + NAD+ a. Yeast in dough runs out of
oxygen, does fermentation, CO 2 causes bubbles in bread
Slide 47
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 O 2 (2ATP).
Slide 48
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
Slide 49
Biology: Grab the lab sheet from the front of the room Read
through it and answer the PRE-LAB Questions! Today 11/27/2013:
Investigate Muscle Fatigue Analyze Data Fermentation Quiz Next Week
Wednesday!! NO Homework!! Have a safe and fun Thanksgiving
Weekend!!
Slide 50
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.
Slide 51
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.
