Let’s see what you learned from yesterday!!

Homework Quiz tomorrow over this information… You will be allowed to use your homework only!!

You must have this sheet with you! You can only answer questions that you have completed!

BIOLOGY: PLEASE GET OUT YOUR HOMEWORK!

Today Nov 14:Homework QuizDescribe the structure of ATPDescribe 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 1. ATP consists of:

a. adenine

b. ribose (a 5-carbon sugar)

c. 3 phosphate groups

Draw an 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)

a. ADP then gets another P added to it (recharged) and is ready to be used again

Energy

Partiallycharged battery

Fullycharged 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!

C. How ATP is used1. During Active transport2. 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 RespirationA. Cellular Respiration is the process that

releases energy by breaking down glucose1. Use oxygen to get energy from

glucose and form ATP molecules2. C6H12O6 + 6O2 --> 6CO2 + 6H2O+ ATP

Glucose + oxygen →carbon dioxide + water + energy

3. EVERY living thing does cellular respiration4. Aerobic- process that requires oxygen5. Anaerobic- process that does not require

oxygen

II.Breaking down glucose A. Glycolysis- in cytoplasm

1. One molecule of glucose is used and 2 ATP are created2. One glucose goes in a 2 pyruvic acids are made3. Small yield but happens so fast, thousands of ATP per ms-Can happen w/o oxygen4. NAD+ →NADH , carries high energy electrons

IN OUT1 glucose 2 pyruvic acid2 ATP (investment) 4 ATP (net gain 2 ATP)NAD+ NADH

B. Kreb’s Cycle-in mitochondria1. Aerobic-need oxygen to do2. Makes CO2 , and ATP3. electron carriers- FADH and NADH, made to use during ETC

IN OUTFAD FADHNAD NADH

2 Pyruvic acid ATP(now the energy source)

4. pyruvic acid is broken apart and energy is used to make ATP, make and release CO2 and transfer high e electrons to FAD and NAD

C. Electron Transport Chain -uses high energy electrons from Krebs cycle to make ATP out of ADP1. Aerobic-takes in O2 and releases water2. Lots of ATP made by ATP synthase- attaches a phosphate group to ADP using hydrogen ions H+3. in mitochondria

IN OUTFADH FADNADH NADO2 H2OADP lots of ATP

D. Totals: With oxygen present Cellular Respiration forms about 38 molecules of ATP per molecule of glucose

III. Breaking down glucose in the absence of OxygenA. Fermentation – releases energy from food molecules in the absence of oxygen

1. Anaerobic- not using oxygen2. Cells convert NADH back into

NAD+3. Glycolysis repeats itself (a lot)

B. 2 types of fermentation: 1. Lactic Acid fermentation-

a. Pyruvic acid that accumulates as a result of glycolysis is converted to lactic acidb. Produced by muscles during exercise

when the body cannot supply enough oxygen1.) Build up of lactic acid causes painful burning

in muscles

2. Alcoholic- Yeasts use; produce small amount of ATPpyruvic 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 ExerciseA.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

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 FatigueAnalyze Data

Fermentation Quiz Next Week Wednesday!! NO Homework!!

Have a safe and fun Thanksgiving Weekend!!

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.
