| Cellular Respiration Chapter 4
ACT #1: Energy 1) What is ENERGY? 2) There are two forms of energy: KINETIC and POTENTIAL. What is kinetic energy and what is potential energy? 3) Chemical bonds (like the ones we �created� using the ball and stick model) are considered what kind of energy? 4) Draw this picture: (Mr. Stick Figure man pushing a boulder up a hill) a. There are two objects containing potential energy. Which two? b. What�s happening at position �C�? c. If Mr. Stick Figure Man exerts 1,000 Kcal to move the boulder to the apex, how much potential energy is stored in the boulder at the top? d. What is the potential energy of the boulder at the bottom of the hill? Where did it go? 5) What is CHEMICAL ENERGY? How do we measure chemical energy? 6) What do cells use energy for? What is this called? Activity #2: Glucose, the Cell�s Source of Energy 1) Is glucose a fat, carbohydrate, or a protein? 2) Please draw the structural formula for me once again. 3) You�ll notice most of the chemical energy in glucose is found in the carbon-to-hydrogen and the carbon-to-carbon bonds. Use arrows to point out each of these two main types of energy-containing bonds in your sketch of the glucose molecule. 4) When glucose is broken down, these bonds are broken down. This is known as chemical bond energy. |
