Chapter 5: How Cells Work Cellular Respiration SCB 101 Prof. Calkins Cellular Respiration Cellular respiration: process through which cells extract energy from food A series of controlled chemical reactions Each step produces both ATP and a molecule that release energy from food and store needed for the next step it as a usable energy source called ATP These molecules are like the cell’s batteries, supporting all the functions of the cell The Chemistry of Cellular Respiration What is the name of the process that transforms energy from food molecules into a form that can be used by the body? a. Cell digestion Recap: b. Electron transport c. Enzymatic breakdown d. Cell respiration What are the three parts of cellular respiration, and which part yields the most ATP? a. Glycolysis, Krebs Cycle, Electron transport; electron transport b. Glycolysis, Krebs Cycle, Electron transport; Recap: Krebs Cycle c. Glycolysis, ATP Cycle, Enzymatic transport; Glycolysis d. Glutamine, Krebs Cycle, Enzymatic transport; Krebs Cycle Where does the majority of cellular respiration occur in the cell? a. The nucleus Recap: b. The golgi apparatus c. The mitochondria d. The RER What do we use ATP for? Muscle contractions Maintaining homeostasis (organ function) Movement! Cellular activities Moving Muscles Muscle fibers are controlled by neurons, which send signals to contract The sliding action is powered by ATP
