All animals, such as these elephants, require A LOT of energy to live, grow, and move!

Animals _________ in order to get the energy they need for life.

eat food

undergo photosynthesis

go to the gas station

go to a restaurant

That's right. Animals get the energy they need to live by eating food.

Grass, roots, and bark provide these elephants the energy they need to live, grow, and move.

Click on the elephants' food to continue.

What else must animals do in order to live?

Do The Dishes

Fight the Ender Dragon

Absorb Sunlight

Breathe

Energy released from breaking the bond.

That's right! Animals must eat food and breathe to live.

Glucose Molecule

When animals breathe, their bodies absorb oxygen gas.

Click on the molecule animals absorb from the air.

Animals that live in the water also absorb this molecule!

We use gills to breathe.

I breathe through my skin.

This dog's lungs absorb oxygen from air and then his circulatory system delivers the oxygen to his cells.

Scroll over the dog for an important message.

Click on the dog's lungs to continue.

Yes! Elephants eat rots, grass, bark as sources of energy.

How does this...

I get that we need to eat and breathe to live...but....

...enable this???

and we will answer this dog's excellent question!

Animals eat food and breathe in oxygen. The food molecules and oxygen chemically react and release the energy needed to power the cells of the body. What is the scientific name for this process?

Photosynthesis

Cellular Respiration

Energy Releasation

WitherSpawning

Yes! During cellular respiration, the energy in food is changed into energy that can be used by the body's cells. Food is made from many larger molecules.

Starch

glucose

glucose

glucose

glucose

glucose

The starch molecule above is made from many _____ molecules bonded together.

glucose

pillager

carbon dioxide

During digestion, starches break down into smaller glucose molecules.

Starch

Click on the system of the dog's body that breaks food down into smaller molecules.

Yes! The digestive system breaks down larger molecules (like starches) into smaller molecules (like glucose).

Next, the circulatory system delivers the glucose molecules to all the cells of the body.

Scroll over the dog for an important message.

Click on one of the glucose molecules getting delivered to cells .

Yes! The digestive system breaks down larger molecules (like starches) into smaller molecules (like glucose).

We can't forget about the very important oxygen molecules! They also get a ride to cells from the circulatory system.

Scroll over the dog for an important message.

Click on one of the oxygen molecules getting delivered to cells .

Energy released from breaking the bond.

Glucose and oxygen molecules get delivered to the many cells that make up the body.

Click on the part of the cell diagram that shows where energy is released.

Once in the cytoplasm of a cell, glucose begins the process of breaking down into smaller molecules.These molecules move into the mitochondria (the powerhouses of the cell) where they react with oxygen and release ATP energy, a form of energy that the cell can use.

Energy released from breaking the bond.

Now that both oxygen and glucose are in the cell, they can react and release energy!

Energy (ATP)

Oxygen Gas

Energy in the form of ATP is released during cellular respiration. What are the two waste products of cellular respiration?

Oxygen Gas

Nitrogen Gas

Eyes of Ender

Carbon Dioxide Gas

Water

Energy released from breaking the bond.

You got it! Carbon dioxide and water are waste products of cellular respiration.

Breathe Out

Breathe In Oxygen Gas

Note: Animals get rid of excess water in many ways; breathing is just one of them.

Animals breathe in oxygen gas and breathe out _______.

potatoes and mutton

nitrogen and ATP

glucose and oxygen

carbon dioxide and water

Yes! The body breathes out the carbon dioxide and some of the water made during cellular respiration and USES the released ATP energy to perform cellular work, such as moving muscles.

Animals eat, breathe, and use cellular respiration to convert the energy stored in ______ into ______energy that cells can use.

DNA, kinetic

silverfish, blaze

food, ATP

carbon dioxide, nuclear

Now that both oxygen and glucose are in the cell, they can be reactions that release energy!

Energy released from breaking the bond.

That's right! Animals use cellular respiration to convert food energy to ATP energy their cells can use. Now check your understanding of cellular respiration by completing a couple of quick activities.

Cellular Respiration

First correctly sort the cards. Then, click on the blue checkbox and follow the directions that appear.
