Write this at the top of page

Would you rather

have 50 $1 bills or 1 $50 bill? Make a decision and provide 3 reasons why

.Slide5

Food for Thought…

2)

Your body needs energy but where do you get it from? Where did that energy source come from? Where did that energy come from? Why is energy able to be transferred like this? (Think about how much energy you are spending now to read and answer this question!)Slide6

Today’s Goals

By the end of today I will be able to: Describe the process of converting ATP to ADP and ADP to ATP

By the end of today I will be able to: Explain the movement of energy from the sun to all organisms

By the end of today I will be able to: Explain the purpose of ATP in organismsSlide7

Essential Question

Why do organisms need to break down sugar and food into ATP?Slide8

Question

Why do organisms need energy?

NOTES

The cells of all organisms need chemical energy in order to do work.Slide9

Question

Does food give you energy?

NOTES

YES: Carbon based molecules (carbohydrates, lipids) found in food store energy in their

BONDS

.

($50)

NO: BUT this energy is ONLY useable AFTER these molecules are BROKEN DOWN

. ($1 bills) Slide10

Question

How can I get energy from these

‘

bonds

’

?

NOTES

Break them

!

Slide11

What is the main energy molecule in living things?

ATP

: Adenosine

Triphosphate

is

used

to

store

and

release

energy.

What do we use in every day life that stores and releases energy?Slide12

ATP

ADP

Energy!Slide13

What is ATP made of?

Adenine (A)

Ribose (sugar)

3 phosphates (Tri Phosphate or TP)

Energy is stored in between the

phosphate bonds.Slide14

How is energy released from ATP?

When the last phosphate is broken off energy is

released

and becomes ADP.Slide15

How is energy stored in ATP?

Energy is

stored

in the new phosphate bond. (Becoming ATP)Slide16

Molecule:

Energy

Chemical energy is stored

between the phosphate bonds.

(Charged Battery)

Energy has been released and the

ADP must gain a Phosphate.

(Battery needs to rechargeSlide17

Copy below your table

1) Explain how energy is stored and released and what happens in the ATP Cycle

2

) Where

do these molecules come from?

3

)What

is the difference between ATP and ADP?Slide18

Check for Understanding

Short Answer-

1)Describe how you do not get energy directly from the food you eat. (must include the vocabulary: ATP, ADP, Food Molecule, Phosphate bond)

SRE format: Statement, Reason, Explanation /evidence. Slide19

PHOTOSYNTHESIS & CELLULAR RESPIRATIONSlide20

Think about it…

What materials does an acorn need to grow in size into a large tree? Select

and explain

all that apply:

Sunlight

Soil

Carbon Dioxide

Oxygen

WaterSlide21

SWBAT describe which organelle/type of organism photosynthesis occurs in.

SWBAT recite the (unbalanced) formula for photosynthesis

SWBAT predict what would happen to the plant

’

s ability to create glucose in different situations.

SWABT analyze scientific theory as applied to plant based experiments.

ObjectivesSlide22

All organisms need

energy to do work

!

There are two main ways they approach this issue:

Some make their own (autotrophs)

Others eat other organisms to get food (heterotrophs)

Fuel for LifeSlide23

Autotroph

(self-feeders)

Auto

=

self

Troph

=

feed

Examples:

Plants

Algae

Green bacteria

Hetero

=

other

Examples:

Animals

Fungi

Most bacteria

Autotroph

vs

Heterotroph

Heterotroph

(other feeders)Slide24

1) What materials do plants need to in order to make their own food?

2) Once they make their own food, what materials do they get rid of as waste

?

Let’s label the reactants and products. Circle the reactants and box the products. Make a bean shape around the formula and label this ‘bean’ the chloroplast.

Reactants are what go in.

Products are what is produced.

Photosynthesis occurs in the chloroplast of plants cells.

Day 2Slide31

Bell Ringer

Two test tubes were filled with a solution of

bromthymol

blue. A student exhaled through a straw into each tube, and the

bromthymol

blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color?

Oxygen

was produced by photosynthesis.

Carbon

dioxide was removed by

photosynthesis.

Carbon

dioxide was produced by

respiration.

Oxygen

was removed by respiration.Slide32

How Do Organisms Get Energy From Food?

Animals cannot make their

own food

like plants can. They are

heterotrophs

.

But, BOTH plants and animals must

break down

(digest) food in order to get

energy

from it (so they can live, grow, & develop)

Cells do this

by

: cellular respirationSlide33

Cellular Respiration

Cellular Respiration = chemical process that happens in

cells

In prokaryotes, it happens in the

cell membranes

In eukaryotes, it happens mostly in the

mitochondriaSlide34

Process of Cellular Respiration

Food (glucose) is broken down into CO

(ATP)

This energy can be used for:

Keeping a constant

body temperature

Storage

(ATP) - to be used later for things like growthSlide35

Who performs respiration?

EVERY LIVING THING!!

Animals, plants, fungi, your dog that ate your homework, weird Uncle Bob…anything that is living.

Every living thing needs to convert sugars into energy so they all perform

RESPIRATION

.Slide36

Check It Out!

Did you notice that cellular respiration is just the

opposite

of photosynthesis?Slide37

Fermentation

If something is in the absence of oxygen it is called

Anaerobic



“not in air”; no oxygen.

If something requires oxygen it is called

Aerobic

needing

oxygen

Fermentation

– process by which cells release energy (ATP) from food molecules in the

absence

of oxygen.

2 types of fermentation:

Alcoholic

and

Lactic Acid

FermentationSlide38
Slide39

Alcoholic Fermentation

Yeast and a few other microorganisms use alcoholic fermentation.

Forms

alcohol

and

CO

2

as wastes.Slide40

We see alcoholic fermentation when bread rises and the production of alcohol.Slide41

Lactic Acid Fermentation

Have you ever had your muscles be stiff and sore when you exercised?

Your muscles run out of oxygen so cells begin rapidly producing ATP by lactic acid fermentation.

The build up of acid causes a burning sensation.

You breath heavily after exercise to repay the

oxygen dept

.Slide42

Imagine if someone wanted to cut down all of the trees on Earth. How would this impact your life and the lives of other animals on the planet?

(2-3 Sentences)Slide50

Key Point #1



Photosynthesis and Cellular Respiration are Interrelated.

Photosynthesis and cellular respiration are completely connected to each other. One can not operate with out the other. Slide51

Key Point #2

-Photosynthesis and Cellular Respiration are

OPPOSITES

of each other.Slide52

How are the reactants and products for photosynthesis related?Slide53

The

products

of

photosynthesis

are the reactants for cellular respiration

and the

products

of

cellular respiration

are the

reactants

for

photosynthesis.Slide54

Reactants or ProductsSlide57

What is the difference between what happens to energy during photosynthesis vs. during cellular respiration?Slide58

Key Point #3-Photosynthesis Captures Energy and Cellular Respiration Releases Energy

Photosynthesis

Captures

energy and

Cellular Respiration

Releases

EnergySlide59

What types of organisms do photosynthesis?

What types do cellular respiration?Slide60

Key Point #4 Plant

use both CR and Photo,

Animals

only do CR

Plants and algae use

BOTH

processes

Animals and mushrooms only use

ONE

process; cellular respiration.Slide61

Key Point- Recap

Photosynthesis and cellular respiration are interrelated.

Photosynthesis and cellular respiration are opposites of each other. The products of photosynthesis are the reactants for cellular respiration and the products of cellular respiration are the reactants for photosynthesis

Photosynthesis captures energy and cellular respiration releases energy.

Plants and animals can use both processes, Animals and mushrooms use only cellular respiration. Slide62
