Chapter 9, Problem 9TYU
MAKE CONNECTIONS The proton pump shown in Figures 7.17 and 7.18 is a type of ATP synthase (see Figure 9.14). Compare the processes shown in the two figures, and say whether they are involved in active or passive transport (see Concepts 7.3 and 7.4).

Discuss how the structure of the SERCA Ca ion pump allows for the passage of Ca across themembrane. Make sure you detail the mechanism of transfer, where does the energy storycome in, timing of shape shifts, etc.
MAKE CONNECTIONS Explain why the set of forces driving ionmovement across the plasma membrane of a cell is described as anelectrochemical (electrical and chemical) gradient (see Concept 7.4).
Q) Diagram in detail the oxidative phosphorylation stage of cellular respiration demonstrating how the bulk of the ATP is made during that stage. Accompanying your diagram should be a paragraph explaining the ATP production process.

- pH and in the Chloroplast Proton-Motive Force (Integrates with Chapter 20.) In mitochondria, the membrane potential () contributes relatively more to p (proton-motive force) than does the pH gradient (pH). The reverse is true in chloroplasts.
