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?So we can reproduceSo we can move aroundSo we can interact with

surroundingsSo our cells can functionThinking

In what form is energy available?GlucoseProteins, carbohydratesFood SolarElectric, water, chemicalWind, lithium ,nuclear, maltose

How does our body convert this energy?ENERGY MUST BE IN CHEMICAL

FORM FOR US TO USE IT!!!!!!!!ATP (adenosine tri phosphate),Mitochondria makes ATP (through

metabolism)Oxygen and glucose are

converted into energy and waste

Where do the waste products go?2 waste products Carbon dioxide (exhale)Water (urinate, sweating, exhale)

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

heat

Tuesday 18 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.• Jhon will come around and collect the 8-1 reading hw quickly and quietly

HW:• Reflections and conclusions questions

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!

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

Now…Take a seat, chill, start quietly

writing your answers

Thursday 20 OctoberTopic: Burning food compared to cellular respiration

DO NOW:• Take a copy of today’s activity and complete the 3 pre-lab questions• Have your hw out for collection

HW:• Complete any lab questions that were not done during class • Study for tomorrow’s quiz (shorter)

ObjectiveBy the end of this class, you will

be able to identify 3 similarities and 3 differences between burning food and cell respiration by igniting a Frito chip.Agenda

Recap of outdoor activitySilent readingLab protocolLab PART II (as a demo)Lab part I (in groups)Review for quiz tomorrow

Outdoor activity recapWhat are the key points to take

away?Exercises increase heart rate

carries oxygen to cells Carbon dioxide from cellsBreathing rate increases to get

more oxygen to make more energy

Silent readingIn order to best understand

today’s lab and to answer all the questions properly, you will need additional information.

The last page of your lab packet was copied from the text

Turn to it and read silently for 5 minutes

Part II – Measuring the Calories in Foodcalorie – amount of energy needed to

raise the temp of one gram of water by one degree celsius

Calorie (aka kilocalorie) – 1000 calories

Quantitative Data:Volume of water 100 mL = 100

gramsStarting temp of water: 22 celsiusEnding temp of water: 27 celsiusChange in temperature: 5 degrees

Lab ProtocolAll bags, extra papers, etc must be off the

lab tableAny hair long enough is to be tied backIMPERATIVE that people stay in their seatsSteps:

◦Secure the frito into the holder apparatus◦Have a cup of water ready to drop match into◦Once I see that all groups are ready, I will

distribute a match to each group◦Light the frito FROM THE BOTTOM, drop the

match into the water, observe the reaction and then fill in the table accordingly.

Burning Food Cell Respiration

General Observations

Chip becomes black/burnt DO NOT ANSWER

Starting materials

Frito chip, match, cup of water, paper clip

Glucose and oxygen

Source of fuel (energy source)

Carbs and lipids (fat) Glucose

End productsBurnt chip/ charcoal Carbon dioxide, water,

heat and ATP

Type(s) of energy released

Heat energy ATP

Catalyst (what triggers the reaction to start)

Match Enzymes in the mitchondria

Number of separate steps of the process

Three steps: prepare, light ,extinguish

Three

SIMILARITIES:Require oxygenBurn glucoseProduce heatConvert one

form of energy to another

DIFFERENCES:• Cell respiration

produces water• Cell respiration

produces ATP• Burning

produces carbon monoxide

Cell Respiration ReviewWith a partner, spend 15 minutes

filling in the study guide questions

1. What is ATP and how is it used in cells?ATP is chemical energy and is

used to power everything in the cell and the body.

2. What is the purpose of cell respiration?The purpose of cell respiration is

to make usable energy.

3. Where does cell respiration happen?It happens in the mitochondria.

4. What are the starting materials and end products for cell respiration?

The starting materials are as follows:

Oxygen and Glucose

The products are:Water, ATP, energy, carbon dioxide, and heat.

5. How is cell respiration similar to and different from actually burning food?

6. What is a calorie?A calorie is one gram of water

heated by one degree Celsius.

7. How does exercise influence cell respiration? Why?It makes you need more glucose

and oxygen, and the rate of cell respiration will increase.

Friday 21 OctoberTopic: Cell Respiration Review & Quiz

DO NOW:• Get a clicker from the kidney table• 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
