Enzyme Structure & Function A FIGURE 1 INTRODUCTORY QUESTIONS A. 650 m B. 1400 m 1. If you're going hiking this weekend and you have the option of hiking a mountain that is 1400 meters in height and a mountain that is 650 meters in height, BUT you know that you have limited time because of other plans - which mountain would you choose to hike, A or B? EXPLAIN WHY. 2. If you're hiking at the same pace, which of these mountains would require MORE energy to hike up (A or B)? Explain.

Stored Energy ATP + water + ATPase = a. ADP + Pi + energy b. ADP + ATPase + heat C. ADP + Pi + Pi d. ADP + heat + water OO00

14-2. Explain whether the following statements are true or false. Justify the false ones.A. Many, but not all, of the electron transfer reactions involve metal ions.B. The electron transport chain generates an electrical potential across the membrane because it moves electrons from the intermembrane space into the mitochondrial matrix.C. The proton electrochemical gradient consists of two components: a difference in pH and an electrical potential.D. Ubiquinone and cytochrome c are both electron carriers that are easily diffused.E. Plants have chloroplasts and therefore can live without mitochondria.F. Both chlorophyll and the heme group consist of a system of double bonds that allow it to absorb visible light.G. The role of chlorophyll in photosynthesis is equivalent to that of the heme group in the mitochondrial electron transport chain.H. Much of the dry weight of a tree comes from the minerals it takes from the ground at its root.
