Review: 1) What do carbohydrates provide? 2) Which foods have a lot of carbohydrates in them? 3) What does your body use energy for? 4) True or False: Energy can be created. 5) What happens to macromolecules like carbohydrates after you eat them? 6) What are the monomers of carbohydrates? When you eat pasta, your body breaks down the carbohydrates in each noodle into _________________________________________ like glucose. However, your body can’t use _________________ as energy directly! Everything you do (move, talk, think, etc.) needs a special form of energy called __________!! How do we get ATP? A process called ________________ ________________________________takes food molecules and changes them into ATP, which your body can use as energy. In other words, cellular respiration is ________________________ one form of energy (glucose) into a useable form of energy (ATP). Think-­‐Pair-­‐Share: Why is cellular respiration important to humans? What I say: What my partner says: What the class says: True or False: All living things need to perform cellular respiration. Be Critical: Where do you think cellular respiration occurs in your body? A) In your stomach B) In your brain C) In your muscles D) All of the above Cellular respiration happens in every __________ of your body because each cell needs energy (ATP) to do what it needs to do (see, hear, move, speak, etc.)! Where (in what organelle) do you think cellular respiration take place? (Hint: Think about the purpose of cellular respiration) Did you get it? (Circle one after Mrs. Reigel tells you the answers): YES NO 1. Cellular respiration produces _____________, a form of energy used by the cell. 2. Why must all organisms perform cellular respiration? 3. Why are mitochondria considered the “battery” for a cell? But how does cellular respiration work? Like any chemical process, cellular respiration begins with __________________. There are two reactants in cellular respiration. One comes from the _________ you eat and the other comes from the _________ you breathe. Based on that information, what are the two reactants of cellular respiration? 1) _______________________________________ 2) _______________________________________ In the ___________________________, these two reactants are changed into three products: one your body uses as _______________, one you _________or sweat out, and one you _____________ out. What are the three products? 1) _________________ 2) ______________________________ 3) _____________________________________________________ Therefore, the overall chemical reaction for cellular respiration is (you need to memorize this!!): In Symbols: In words: Think-­‐Pair-­‐Share: Why does your body need oxygen to survive? What I say: What my partner says: What the class says: Think-­‐Pair-­‐Share: When would your body need to perform more cellular respiration than usual? What I say: What my partner says: What the class says: Be critical: What type of molecules control the reaction rate of cellular respiration (speed it up or slow it down)? _______________________________ Practice Problems 3. _______________________ and
1. What kind of gas is produced by cellular
respiration?
_________________________ are
a. Water vapor
consumed in cellular respiration
b. Oxygen
a. Water and oxygen
c. Carbon dioxide
b. Glucose and water
d. Carbon monoxide

result, the mitochondria cannot produce:
c. ATP
a. Water
d. Water

When you eat pasta, your body breaks down the carbohydrates in each noodle into monosaccharides like glucose. However, your body can’t use glucose as energy directly! Everything you do (move, talk, think, etc.) needs a special form of energy called ATP. How do we get ATP? A process called cellular respiration takes food molecules and changes them into ATP, which your body can use as energy.

But how does cellular respiration work? Like any chemical process, cellular respiration begins with reactants. There are two reactants in cellular respiration. One comes from the food you eat and the other comes from the air you breathe. Based on that information, what are the two reactants of cellular respiration? 1) _______________________________________ 2) _______________________________________ In the mitochondria, these two reactants are changed into three products: one your body uses as energy, one you pee or sweat out, and one you breathe out. What are the three products? 1) _________________ 2) ______________________________ 3) _____________________________________________________ Therefore, the overall chemical reaction for cellular respiration is (you need to memorize this!!): In Symbols: In words: Think-­‐Pair-­‐Share: Why does your body need oxygen to survive?
