Monday 17 October Topic: Cellular Respiration DO NOW: Brainstorm everything that you can about energy. Think about things such as where it comes from, how it becomes available, how does it change into other forms, what is it used for, what types there are, etc. HW: 8-1 Reading for Understanding (complete classwork from Friday – you will get your sheet back and a copy of the reading)

Objective By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products. Agenda Quick announcements Notes on cell respiration

Why do we need energy? To do work To survive To power ourselves To make heat To maintain homeostasis OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products.

In what form is energy available? Kinetic Energy Solar Energy Potential Energy Chemical Energy Magnetic Energy OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products.

How does our body convert this energy? WE MUST USE CHEMICAL ENERGY(ATP) Adenosine tri-phopshate(we don’t eat ATP) We make it by breathing and eating Mitochondria converts reactants into usable ATP (breathing in oxygen and eating glucose) OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products.

Where do the waste products go? There are 2 waste products( carbon dioxide and water) To exhale Sweating, urination, and exhaling OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products.

THE FORMULA!!! O 2 + C 6 H 12 O 6  CO 2 + H 2 O + ATP + heat OBJECTIVE – By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products.

Tuesday 18 October Topic: Exercise, Cell Respiration, and your body DO NOW: Pick up a packet from the kidney table and complete the front page (“pre-lab”). You should fill in the blanks and write hypotheses for how exercise affects the body. Andre will come around and collect the 8-1 reading hw quickly and quietly HW: Reflections and conclusions questions

Objective Explain how the chemical equation for cell respiration relates to breathing, and why we breathe harder during exercise. Agenda Protocol for outdoor activity How to measure a pulse Outside activity!

Pulse & Breathing rate Everyone focus for a few seconds and note if your breathing is slow, medium, or fast (compared to how you normally breathe) Next, find your pulse on your neck or your wrist and we will measure it for 15 seconds ◦ Multiply this number by 4 to get beats/min (bpm)

Before going outside… You only need to bring your lab and a pencil and can leave everything else here We go out the back stairs, out the door, and around to the crosswalk Line up with your partner along the edge of the basketball court by the red stairs Once everyone completes the activity, listen for me to say “Now” and “End” which will be the timed minute for pulse Swap with your partner

Now… Take a seat, chill, start quietly writing your answers

Wednesday 19 October Topic: Measuring energy in food DO NOW: Pick up a lab packet from the kidney table and complete the pre-lab assignment HW: Post-lab analysis questions

Objective Identify 3 similarities and 2 differences between cell respiration and burning food. Calculate the number of calories in a Frito Agenda Lab protocol Demo of burning food Labs part 1 & II

Lab Protocol All bags/excess paper/etc must be off lab tables Any hair long enough is to be tied back During the burning portion, absolutely no getting up for anything (wait until after this portion of the lab is complete) Nothing is going near the flame! Identify 3 similarities and 2 differences between cell respiration and burning food. Calculate the number of calories in a Frito

Friday 21 October Topic: Cell Respiration Review & Quiz DO NOW: Get a clicker from the kidney table Take out your notes on cell respiration HW: Read 38-1 and take notes in your notebook Think of a food/meal that contains carbohydrates, lipids (fats), and proteins. Write it down after your reading notes!

Objective By the end of this class, you will be able to apply knowledge of cellular respiration to answer short-answer and open- response questions on the quiz Agenda Cell respiration review Lab review (exercise and burning food) Quiz

1. What do you call the starting materials in a chemical equation? A. Products B. Ingredients C. Reactants D. Starters

2. What are the reactants in cellular respiration? A. O 2 and CO 2 B. O 2 and Glucose C. Glucose and ATP D. CO 2, H 2 O, ATP, and heat

3. What are the products in cellular respiration? A. O 2 and CO 2 B. O 2 and Glucose C. Glucose and ATP D. CO 2, H 2 O, ATP, and heat

4. What is the purpose of cellular respiration? Why is it important? A. To help us breathe B. To make glucose for cells C. To make ATP for cells D. To take in oxygen and release carbon dioxide

5. The organelle where cell respiration takes place is the A. Nucleus B. Lysosome C. Chloroplast D. Vacuole E. Mitochondrion F. Ribosome

6. Why do some cells have more mitochondria than other cells? A. The cells use more energy B. The cells store more nutrients C. The cells degrade more proteins D. The cells divide more frequently

7. A poison that prevents cell respiration in mitochondria will affect the production of… A. ATP B. Glucose C. Oxygen D. RNA

8. Choose the correct statement about photosynthesis and cell respiration: A. Both in same organelle B. Both happen in all living things C. P produces carbon dioxide, and CR uses carbon dioxide D. P stores energy and CR releases energy

9. Which happens in the reaction on your paper? A. Energy from ATP is used to make glucose B. ADP adds a high-energy bond to its structure C. ADP is used to provide oxygen to a cell D. Energy is stored in ATP for future use

10. Which conclusion is best supported by the graph? A. ATP production is independent of sugar B. Amount of cell respiration is constant C. ATP is only produced when sugar is above 4 g/L D. Amount of cell resp. increases as sugar concentration increases

Question 10

Exercise Lab Review Why does breathing rate increase during exercise (2 reasons)? ◦ Necessity of oxygen ◦ Releasing carbon dioxide Why does heart rate increase during exercise? ◦ Blood carries the stuff for cell respiration (reactants & products) Does the amount of cell respiration increase during exercise? Why or why not? ◦ Yes! Cell respiration increases because you need more energy.

SIMILARITIES: both require oxygen both require glucose both contain heat both convert one form of energy to another DIFFERENCES: cell respiration also makes ATP energy also makes water Carbon monoxide Burning food lab

What was the source of energy in the Frito? (i.e. what fueled the fire) If the Frito was not consumed by fire, what would happen to it if it was eaten? How would you summarize the two reactions in terms of energy conversion?

IF you finish early: ◦ Take a text from the cabinet, go to the back, and start reading 38-1 (hw) and taking notes in your notebook
