Monday 17 OctoberTopic: Cellular Respiration

DO NOW:• Brainstorm everything that you can about energy. Think about things such as where it comes from, how it becomes available, how does it change into other forms, what is it used for, what types there are, etc.HW:• 8-1 Reading for Understanding

ObjectiveBy the end of this class, you will

be able to write the chemical equation for cell respiration and identify its reactants and products.

AgendaNotes on cell respiration

Why do we need energy?Heterotrophs and AutotrophsThe ability to do workTo liveTo power functions in the cellTo do your homework (muscle

fiber, thinking) To move

In what form is energy available?Solar energyElectric energyKineticChemicalPotential Nuclear

How does our body convert this energy?ENERGY MUST BE AS ATPAdenosine Tri-phosphateWe do not eat ATPThe mitochondria makes it with

metabolism What it takes in is called

reactants Products come out of a reaction

Where do the waste products go?There are two waste products#1- Carbon dioxide-exhaling#2- Water-urinating, sweating,

and exhaling

THE FORMULA!!!O2+ C6H12O6 CO2 + H2O + ATP

Tuesday 18 OctoberTopic: Measuring energy in food

DO NOW:• Pick up a lab packet from the kidney table and complete the pre-lab assignment

HW:• Post-lab analysis questions

ObjectiveIdentify 3 similarities and 2 differences

between cell respiration and burning food.

Calculate the number of calories in a Frito

AgendaLab protocolDemo of burning foodLabs part 1 & II

Lab ProtocolAll bags/excess paper/etc must

be off the lab tablesAny hair long enough is to be tied

backDuring the burning portion,

absolutely no getting up for anything (wait until after this portion of the lab is complete)

Identify 3 similarities and 2 differences between cell respiration and burning food.Calculate the number of calories in a Frito

If you’ve finished…Part I (burning food) of the lab

◦Complete the table on pg 1◦Write the analysis comparing and contrasting

burning food to cell respiration

Part II (measuring calories)◦Make sure all your data is filled in

Both parts of the lab◦Make sure all lab pieces are in the metal tray◦Start on the remainder of the analysis questions

Identify 3 similarities and 2 differences between cell respiration and burning food.Calculate the number of calories in a Frito

Thursday 20 OctoberTopic: Exercise, Cell Respiration, and your bodyDO NOW:• Pick up a packet from the kidney table and complete the front page (“pre-lab”). You should fill in the blanks and write hypotheses for how exercise affects the body.

HW:• Reflections and conclusions questions• Study for quiz

ObjectiveExplain how the chemical

equation for cell respiration relates to breathing, and why we breathe harder during exercise.

AgendaProtocol for outdoor activityHow to measure a pulseOutside activity!

Pulse & Breathing rateEveryone focus for a few seconds

and note if your breathing is slow, medium, or fast (compared to how you normally breathe)

Next, find your pulse on your neck or your wrist and we will measure it for 15 seconds◦Multiply this number by 4 to get

beats/min (bpm)

Before going outside…You only need to bring your lab and a

pencil and can leave everything else here

We go out the back stairs, out the door, and around to the crosswalk

Line up with your partner along the edge of the basketball court by the red stairs

Once everyone completes the activity, listen for me to say “Now” and “End” which will be the timed minute for pulse

Swap with your partner

Friday 21 OctoberTopic: Cell Respiration Review & Quiz

DO NOW:• Get a clicker from the kidney table and review sheet• Take out your notes on cell respiration

HW:• Read 38-1 and take notes in your notebook• Think of a food/meal that contains carbohydrates, lipids (fats), and proteins. Write it down after your reading notes!

ObjectiveBy the end of this class, you will

be able to apply knowledge of cellular respiration to answer short-answer and open-response questions on the quiz
