12/11/2015 – ATP AND PHOTOSYNTHESIS
LEARNING TARGET/ESSENTIAL
QUESTION:
IDENTIFY THE REACTANTS
AND PRODUCTS OF
PHOTOSYNTHESIS
WHAT IS ATP AND HOW
DOES IT WORK?
• ET: GLUE IN YOUR NEW
OBJECTIVES AND COMPLETE THE
“BEFORE UNIT” SELF ASSESSMENT
* IN YOUR NOTEBOOK, PREREFLECTION: LIST EVERYTHING YOU
ALREADY KNOW ABOUT
PHOTOSYNTHESIS
ATP – WHAT DO THESE LETTERS STAND FOR?
• ADENOSINE TRI-PHOSPHATE
• STORED CHEMICAL ENERGY FOR THE CELL
• IT RELEASES THE ENERGY STORED IN IT’S BONDS BY BREAKING
INQUIRY: MAKING PREDICTIONS, OBSERVING, ASKING QUESTIONS
Q: WHICH CANDLE WILL BURN THE LONGEST?
WHAT IS YOUR PREDICTION AND WHY?
CANDLE IN A JAR: MINI LAB
• CREATE A DATA TABLE IN YOUR
NOTEBOOK TO RECORD THE TIME
AND OBSERVATIONS FROM THIS MINI
LAB
• MATERIALS
PLANT
2 TEA LIGHT CANDLES
MATCHES
2 GLASS COVERINGS
STOPWATCH
• PROCEDURE:
1. ONCE YOUR SET UP IS IN PLACE
LIGHT BOTH CANDLES ONE AT A
TIME KEEPING THE GLASS
COVERING OFF
2. ONCE THEY ARE BOTH LIT, PLACE
THE COVERS OVER THE CANDLES
AT THE SAME TIME (THIS MAY
REQUIRE TWO PEOPLE)
3. HAVE A TIMER START THE
STOPWATCH AS SOON AS THE
COVERINGS ARE OVER THE
CANDLES
4. RECORD THE TIME THAT WHEN
EACH CANDLE STOPS BURNING
CONCLUSIONS:
BASED ON OUR DATA/EVIDENCE, WHAT
CAN WE DAY ABOUT TWO JARS?
• WHICH CANDLE BURNED OUT FIRST? IDEAS WHY?
• WHAT IS THE SIGNIFICANCE OF THE PLANT?
• DID WE LEARN ANYTHING ABOUT PLANTS OR
PHOTOSYNTHESIS FROM THIS?
BE READY TO SHARE YOUR RESPONSES
CONCLUSIONS TO DRAW FROM THIS:
• WHAT IS THE PURPOSE OF THE PLANT?
WHAT IS IT SUPPOSED TO BE DOING?
• WHAT PROCESSES DO PLANTS DO? WHAT
DO THOSE PROCESSES MAKE?
PHOTOSYNTHESIS VS. CELLULAR RESPIRATION –
12/14/2015
• LT/EQ: TODAY I WILL…
Q: WHAT IS THE RELATIONSHIP
BETWEEN THESE TWO PROCESSES
• COMPARE THE REACTANTS AND
PRODUCTS OF PHOTOSYNTHESIS
WITH THE REACTANTS AND
PRODUCTS OF CELLULAR
RESPIRATION
• ET: DRAW THE DIAGRAM
PHOTOSYNTHESIS PG. 233
• WHERE ARE THE REACTANTS
GOING INTO THE
CHLOROPLAST?
• WHERE ARE THE PRODUCTS
COMING OUT OF THE
CHLOROPLAST?
POGIL
LETS IDENTIFY THE LEVEL OF QUESTIONING
GOING ON IN THIS ACTIVITY
• USING YOUR DOK (DEPTH OF KNOWLEDGE)
QUESTION STEMS GO THROUGH THE FIRST 12
QUESTIONS
• IDENTIFY AND LABEL THEM AS LEVEL 1, 2, 3, 4
STOP AFTER THE FIRST STOP SIGN
12/15/2015 – PHOTOSYNTHESIS AND CELLULAR
RESPIRATION
• LT: TODAY I WILL…
• ET: DEFINE/DESCRIBE THE
FOLLOWING TERMS (5 MIN.)
1. EXPLAIN THE PROCESS OF
PHOTOSYNTHESIS
• AUTOTROPH
2. MAKE PREDICTIONS
CELLULAR RESPIRATION AS
IT RELATES TO EXERCISE
• PIGMENT
• HETEROTROPH
• CHLOROPHYLL
• STROMA
• THYLAKOID
AUTOTROPHS VS. HETEROTROPHS
• WHAT ARE AUTOTROPHS? WHAT DO THEY MAKE?
• WHAT ARE HETEROTROPHS? WHAT DO THEY NEED?
ELECTRONS? CARRIER MOLECULES?
• NADP+ = NICOTINAMIDE ADENINE DINUCLEOTIDE PHOSPHATE
• WE CALL IT A “CARRIER” BECAUSE LIKE ATP, IT TRAPS A HIGH ENERGY ELECTRON
IN IT’S BONDS AND TAKES WHERE IT NEEDS TO GO IN THE CHLOROPLAST
WHAT IS PIGMENT AND WHAT DOES IT DO?
• A LIGHT ABSORBING MOLECULE
• CHLOROPHYLL IS THE PIGMENT IN THE CHLOROPLAST
ELECTRONS? FROM WHERE?
What happens
when chlorophyll
is struck by light?
PLANT LAB CONCLUSIONS
CELLULAR RESPIRATION MINI LAB
HOW WILL EXERCISE AFFECT THE RATE OF CELLULAR
RESPIRATION IN YOUR CELLS?
WRITE THE QUESTION AND YOUR HYPOTHESIS IN YOUR NOTEBOOK
WHAT ARE YOUR VARIABLES: READ THROUGH THE LAB

RESPONDING/DEPENDENT:______________________
12/16/2015 – CELLULAR RESPIRATION
• LT: TODAY I WILL…
• EXPLAIN THE PROCESS OF CELLULAR
RESPIRATIONS
• IDENTIFY ALTERNATIVE METHODS OF
ATP PRODUCTION FOR THE CELL WHEN
OXYGEN IS NOT AVAILABLE
ET: DEFINE THE FOLLOWING
1. AEROBIC
2. ANAEROBIC
CELLULAR RESPIRATION MINI-LAB
BACKGROUND INFORMATION
• CO2 IS A WEAK ACID
• BTB SOLUTION TURNS YELLOW IN THE PRESENCE OF ACID, SO….
*EACH PERSON GETS ONE STRAW AND USES IT FOR THE ENTIRE
EXPERIMENT. DO NOT THROW YOUR STRAW AWAY UNTIL YOU ARE
DONE
FINISH YOUR TRIALS FOR THE
MINI LAB
ONCE YOUR GROUP IS DONE – SIT TOGETHER AND WRITE YOUR
CONCLUSIONS. GUIDING QUESTIONS WILL BE ON THE BOARD
CONCLUSIONS
• WHAT HAPPENED IN THE LAB?
• DID IT SUPPORT YOUR PREDICTION? PROVIDE
ACTUAL DATA TO SUPPORT THIS
• YOUR REASONING ON WHY THIS HAPPENED –
SHOULD RELATE TO WHAT YOU KNOW ABOUT
CELLULAR RESPIRATION
CARD SORT
• CUT OUT ALL OF YOUR CARDS AND MITOCHONDRIA
• WHAT IS CELLULAR RESPIRATION? FIND THAT CARD AND
WRITE A SHORT DESCRIPTION ON THE BACK
• WHAT IS GLYCOLYSIS? FIND THAT CARD AND WRITE A
SHORT DESCRIPTION ON THE BACK
• WHAT IS LACTIC ACID FERMENTATION? FIND THAT CARD
AND WRITE A SHORT DESCRIPTION ON THE BACK
CARD SORT – YOUR DESK IS A CELL
• ARRANGE THE CARDS IN THE ORDER THAT CELLULAR
RESPIRATION OCCURS – YOU MAY USE SOME OR ALL OF
THE CARDS
LETS SHARE OUR RESULTS
Q: WHAT PROCESSES IN CR REQUIRE OXYGEN? – PLACE YOUR
OXYGEN NEAR THAT PROCESS
Q: WHAT TYPE OF PROCESS IS THIS
Q: WHAT IF OXYGEN IS NOT AVAILABLE?
WHAT IS CELLULAR RESPIRATION?
• WHEN YOUR CELLS USE GLUCOSE AND OXYGEN
TO MAKE ATP ENERGY
1ST - GLYCOLYSIS
• GLYCOLYSIS: THE SPLITTING OF
GLUCOSE HAPPENS IN THE
CYTOPLASM OF THE CELL
• RESULT: 2 PYRUVIC ACID OR
PYRUVATE MOLECULES
IF OXYGEN IS AVAILABLE…
2ND – THE KREB CYCLE (CITRIC ACID CYCLE)
3RD – ELECTRON TRANSPORT CHAIN (ETC)
IF OXYGEN IS NOT AVAILABLE…
• 2ND - FERMENTATION: 2
TYPES
• LACTIC ACID: 2
ATP’S, MAKES YOU
SORE
• ALCOHOL: 2 ATP’S,
MAKES ALCOHOL
AEROBIC VS. ANAEROBIC
LOOK UP THESE TERMS ON PG. 252
• WHAT DO THEY MEAN
• HOW CAN WE REMEMBER THE
DIFFERENCE BETWEEN THEM?
