TEKS 7.9 A TEKS 9B Cellular Respiration TAKS Objective 2 – The student will demonstrate an understanding of living systems and the environment. TEKS Science Concepts 9 B The student knows metabolic processes and energy transfers that occur in organisms. The student is expected to: (B) compare the energy flow in photosynthesis to the energy flow in cellular respiration TAKS Objective 2 page 1

TEKS 7.9 A For Teacher’s Eyes Only Teacher Background: Cellular respiration is a complex concept that must be taught. In these activities, we will introduce cellular respiration and its components to students. In later activities, students will be able to compare the energy flow of cellular respiration to photosynthesis. A brief description of cellular respiration follows: Cellular Respiration – . Student Prior Knowledge Students should be familiar with the components associated with body systems TEKS 6.10 (C) identify how structure complements function at different levels of organization including organs, organ systems, organisms, and populations and the functions of these systems.

TEKS 7.9 A 5 E’s ENGAGE Obtain small Nerf Toys that shoot soft darts. As students are waiting to begin class, shoot the soft darts around the room. This toy is a great representation of the molecule ATP. Tell students that our body obtains energy by making a molecule called ATP from the foods we eat. Show students the picture of the molecule and describe which parts represent Adenine (handle), Ribose (barrel) and Phosphates (dart). Later on during the lesson, students will see that when ATP looses a phosphate it give off energy, which is represented in the shooting of the dart. h EXPLORE Exploration 1 Cellular Respiration Simulation Activity Activity Overview: This is a role-playing simulation where the students act as the enzymes of cellular respiration to break down a glucose "molecule." The purpose of the activity is to review the "big picture" of metabolism, aiding students in understanding the relationship among glycolysis, the Kreb's cycle, and the ETC. See Blackline Masters for the simulation layout and detailed directions. TAKS Objective 2 page 3 ATP, ENERGY!

TEKS 7.9 A Exploration 2 Muscle Fatigue Students work in pairs to complete the following experiment to investigate the relationship between oxygen and muscle fatigue. Use the following procedure to explore lactic acid buildup in muscles. 1. Each pair of students is given a tennis ball. 2. Partner A holds the ball in his or her hand. Either hand is OK. 3. Partner B monitors the time for two minutes. 4. When Partner A says begin, Partner B squeezes the tennis ball with his or her hand as many times as possible until time is called at the end of two minutes. Simultaneously, Partner A will count aloud the number of times the tennis ball is squeezed. 5.
