Monday 17 October

Topic: 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

Objective

By the end of this class, you will be able

to write the chemical equation for cell

respiration and identify its reactants and

products.

Agenda

Notes on cell respiration

Why do we need energy?

So we can reproduce

So we can move around

So we can interact with surroundings

So our cells can function

Thinking

In what form is energy available?

Glucose

Proteins, carbohydrates

Food

Solar

Electric, water, chemical

Wind, 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 + C6H12O6ATP + H2O + CO2 + heat

Tuesday 18 October

Topic: Exercise, Cell Respiration, and

your body

DO 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

Objective

Explain how the chemical equation for

cell respiration relates to breathing, and

why we breathe harder during exercise.

Agenda

Protocol for outdoor activity

How to measure a pulse

Outside 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 October

Topic: 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)

Objective

By 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 activity

Silent reading

Lab protocol

Lab PART II (as a demo)

Lab part I (in groups)

Review for quiz tomorrow

Outdoor activity recap

What are the key points to take away?

Exercises increase heart rate carries

oxygen to cells

Carbon dioxide from cells

Breathing rate increases to get more

oxygen to make more energy

Silent reading

In 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 Food

calorie – 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 grams

Starting temp of water: 22 celsius

Ending temp of water: 27 celsius

Change in temperature: 5 degrees

Lab Protocol

All bags, extra papers, etc must be off the lab table

Any hair long enough is to be tied back

IMPERATIVE that people stay in their seats

Steps:◦ 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 materialsFrito 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 oxygen

Burn glucose

Produce heat

Convert one form

of energy to

another

DIFFERENCES:

• Cell respiration

produces water

• Cell respiration

produces ATP

• Burning produces

carbon monoxide

Cell Respiration Review

With 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 October

Topic: 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!

Objective

By the end of this class, you will be able
