Cellular Respiration Chapter 2: Lesson 2 Page 50

What Happens During Cellular Respiration? You eat Your body breaks food down Sugar in food is released in the form of glucose (Glucose = C6H12O6) CELLULAR RESPIRATION is the process by which cells obtain energy from glucose.

Find the key!!! During cellular respiration, cells break down glucose and other molecules from food in the presence of oxygen, releasing energy.

Storing and Releasing Energy Your body stores and uses energy When you eat, you add to your body’s energy savings account When cells need energy, they “withdraw” it by breaking down glucose through cellular respiration. See Figure 1, Page 51

Cellular Respiration – color the last three energy scales to show how the hiker’s energy changes. Getting Energy How does the hiker's energy and breathing rate change as she climbs?

Cellular Respiration Getting Energy How does the hiker's energy and breathing rate change as she climbs?

Breathing and Respiration What is the difference? Breathing: moving air in and out of your lungs Breathing: brings oxygen into your lungs. Breathing: removes waste products of cellular respiration. WRITE THIS: RESPIRATION is using the oxygen to create energy.

#2. Challenge: How do you think the hiker’s breathing rate changes as she climbs? The hiker would breathe faster and deeper in order to get more oxygen needed to make more energy in cells. http://www.bing.com/images/search?q=hiker+breathing+cartoon&view=detailv2&&id=81FC903B57E1DC219151148C25BE7E94B49C3995&selectedIndex=17&ccid=LNxf%2bnT1&simid=608041119329357025&thid=OIP.M2cdc5ffa74f5884fce447501f6570889o0&ajaxhist=0

The Two Stages of Cellular Respiration - Page 52 The first stage takes place in the cytoplasm Molecules of glucose are broken down into smaller molecules Small amount of energy released The second stage takes place in the mitochondria Molecules of glucose are broken down even smaller Requires oxygen and releases LOTS of energy

Cellular Respiration - fill in the missing terms in the spaces provided. Releasing Energy Cellular respiration takes place in two stages. What terms will complete the sentences?

Cellular Respiration Releasing Energy Cellular respiration takes place in two stages. What terms will complete the sentences? Mitochondria Glucose carbon dioxide Energy energy

The Cellular Respiration Equation C6H12O6 + 6O2 6CO2 + 6H2O + ENERGY Raw materials: glucose and oxygen You get glucose from food & oxygen from air. Products: Carbon dioxide, water and energy

Comparing Two Energy Processes Photosynthesis and cellular respiration can be thought of as opposite processes. See Figure 3. Try to figure out what goes in the blanks. Words in the word bank can be used more than once.

Comparing Two Energy Processes Opposite Processes Producers carry out photosynthesis, but producers and consumers both carry out cellular respiration. Use the word bank to complete the blank boxes.
