Class 1: Respiration

​

​

Have you ever wondered how a cell 

creates the energy it needs to function?

​

This energy is obtained thanks to the combination

of the products of two essential processes our 

body has: nutrition and breathing!

​

It is basically the opposite process of photosynthesis,

our cells use the glucose we eat in the carbohydrates and

the oxygen we breathe in, to produce  energy molecules.

​

But here's the really cool part: as the energy is released from these reactions, it's stored in a special molecule called ATP. This molecule acts like a little battery that your cells can use to power all their different processes, from making new cells and to repair damaged tissue.

​

So there you have it - cellular respiration is the process by which your cells break down glucose and oxygen to release energy, this energy is stored in ATP and used to power all the amazing things your body can do!

​

Today we will learn about this interesting process, what is it? where does it happen? how is it related to cellular transport? ... Our purpose is to know the basics of cellular respiration.

​

​

​

​

​

1) Visit the Kids.Kiddle website and write the chemical formula and the word equation for the respiration process. Explain the process with your own words.

​

​

2) Each organelle has a specific function in the cell, which is the organelle responsible for cellular respiration? Which human body parts contain more of these organelles?(Britannicawebsite)

​

3) Draw the image below,  and based on it, explain how photosynthesis in plants and respiration in humans complement each other, and what would happen if there is an unbalance in one of these 2 processes?

​

​

4) Read the definition of respiration on the KidsBritannica website and answer: what is the difference between respiration and breathing? You can also check these two images to understand their difference:

Class 3: Types of Cellular

Respiration

​

Using oxygen is not the only way our cells can produce

energy. Cells are also equipped with an "emergency"

path for those moments in which oxygen is not as

available as usual. For example, when you are late

and you must run 2 blocks all of the sudden, your

lungs don't breathe fast enough to produce all the

energy you need in that moment, that's when the

activate the emergency path called "Anaerobic respiration"

​

Today we will learn about anaerobic respiration, how does it happen?, what part of the cell does this? and we'll also learn how have we taken advantage of the organisms that perform anaerobic respiration to create delicious products like bread, yogurt, cheese, wine, and beer.

​

Let's start by learning a little more about the types of respiration:

​

​

​

​

​

​

Now, we will solve the following activities:

​

​

​

​

​

​

1) How many molecules of ATP are produced in aerobic respiration?

Is it an efficient process? What about anaerobic respiration?

(From the youtube video)

​

2) Mention 4 processes in the human body that require

aerobic energy (From the youtube video)

​

​

3) Go to the BBC website read the main aspects about the types of respiration and write the formula for anaerobic respiration in humans and the formula for anaerobic respiration in bacteria and fungi. BEFORE YOU LEAVE THE WEBSITE SOLVE THE QUIZ THAT APPEARS AT THE BOTTOM.

​

4) In the groups you were assigned, Investigate how fermentation or anaerobic respiration is used by a microorganism to produce food. Create a little presentation or infographic where you include: name of the organism, the product they create, and the process to do it.

​

Group 1: Yogurt                             Group 2: Cheese

​

Group 3: Beer                            Group 4: Wine

​

Group 5: Bread

​

At the end of the class the groups will present their product
