Warm-UP – 1. ________ is the process in plants by which water is

taken up (absorbed) by the roots and released as water vapor through stomata in the leaves

2. _______ is a natural cycle in which carbon compounds, mainly carbon dioxide, are made part of plants through photosynthesis and RETURNED to the atmosphere by respiration, decay of dead organisms and the burning of fossil fuels3.  ________ is where a plant takes in carbon dioxide from the air and water from the soil and turns these things into a sugar called glucose, releasing oxygen and water as by-products.4. _____ is the process of taking in the oxygen produced by plants and releasing carbon dioxide from the body

The reason you eat and breathe is because your cells need nutrients so they can make energy.

In this lesson, you will learn how your body uses cellular respiration to make energy.

Cellular Respiration

All organisms require the input of energy to complete their life cycles.

Energy in organisms is the ability to do work or cause change;

Energy can be stored in chemicals found in food and released to the organism to do work

When you run and jump, your body is using energy.

Why Is Cellular Respiration Important?    

Where does that energy come from?

It comes from the food you eat. Energy for your body is stored as chemicals in the food.

When your body digests the food, it takes in the energy and stores it in your muscles and other cells until you need it.

Cellular respiration supports all of the functions happening in your body by converting the energy in food to a form of energy that your cells can use to perform their functions.

Glucose and oxygen enter cells through the cell membrane.      

Take in a deep breath. Your lungs fill with the many different types of gases that make up the air around you. The most important gas for humans is oxygen. Our bodies need oxygen to live. Plants give off oxygen during photosynthesis.

Cell membrane is the boundary that surrounds a cell and controls which substances can enter or leave the cell

The cell membrane is the outer covering of a cell. It keeps all cell materials inside.

Video 1 - Cellular Respiration Cellular respiration is the complex series of

steps that take place in our cells which release energy from food.

Video 2* - Cellular Respiration Glucose and oxygen enter cells through the cell

membrane. Cellular respiration releases energy stored in food. It also produces carbon dioxide and water as waste products that exit the cell through the cell membrane.

During respiration, glucose and oxygen react to form the products carbon dioxide, water, and ATP. (Adenosine triphosphate)

Cellular respiration releases energy stored in food.

Cellular respiration also produces carbon dioxide and water as waste products that exit the cell through the cell membrane. 

What Are the Reactants and Products of Cellular Respiration?

5/28 Warm-UP Class resumes!!

Respiration

glucose + oxygen carbon dioxide + water + energy (ATP)

reactants products

ATP is Adenosine triphosphate (ENERGY)

Occurs in the MITOCHONDRIA of a cell

  Animals and plants both need to convert food

energy into usable forms this occurs during cellular respiration.

Energy is stored in all chemical bonds, including those of foods.

The body converts foods into glucose, and glucose and oxygen pass into the body's cells.

Then processes in the cytoplasm extract the energy from the atomic bonds in glucose.

Enzymes break up the glucose molecules, releasing the energy.

What Is Cellular Respiration? 

This energy is later transferred into another kind of molecule called ATP

ATP supplies direct energy to cells. The process of cellular respiration also

produces carbon dioxide and water. (by products)

Cellular Respiration

PhotosynthesisCarbon dioxide + water glucose + oxygen + water

sunlight

glucose + oxygen carbon dioxide + water + energy (ATP)

Cellular Respiration: Releasing Stored Energy By Breaking Down Glucose

During cellular respiration, the chemical bonds of glucose are broken down in the presence of oxygen to produce energy.

How these atoms stick together to form substances is called chemical bonding. 

Video 3 -

Only animals perform cellular respiration.

Plants get their energy from photosynthesis. Actually, the food energy made from photosynthesis must still be transformed into a usable form by cellular respiration.    

Interact (DE) – Cellular respiration

Misconception

Digestion converts food to glucose; enzymes in our bodies break down the food into glucose

Glucose goes to the mitochondria

Mitochondria’s purpose is to convert glucose into ATP

Reading (DE)– The process of respiration

1. GLYCOLYSIS – occurs in the cytoplasm of the cell; glucose is broken down into a PYRUVATE molecule

2. Krebs Cycle –occurs in the mitochondria of the cell; PYRUVATE molecule enters the mitochondria; chemical reactions take place and 2 ATP are created. (carbon dioxide – waste product; we breath it out)

3. Electron Transport Chain – occurs on an inner membrane in the mitochondria. A series of chemical reactions take place –oxygen is used; 34 ATP are created

STEPS of Cellular RESPIRATION

1. Summarize your plant observations and experiences. (put it all together – days watered vs. not watered, growth, repotted, staked, death)

2. What did you discover regarding plants and plant growth during this process. What surprised you???

3. If you were to do this over, what would you do differently?
