Textbook Question
Chapter 9.4, Problem 3CC
MAKE CONNECTIONS Ø Membranes must be fluid to function properly (as you learned in Concept 7.1) How does the operation of the electron transport chain support that assertion?

Can you explain why when the pH level was changed from 0 to 5, the ATP production was affected despite the supply of glucose being constant at just 1 mol for both treatments (At 0 pH and 5 pH). What is the reason on why this could have happened?
Protons move across the thylakoid membrane in both directions during the light reactions of photosynthesis......
1. When protons move in to the thylakoid, are they moving up or down their concentration gradient? (From low to high concentration or from high to low concentration?)
2. Since protons are charged, they cannot freely diffuse across a plasma membrane. What protein(s) facilitate the transport of protons in to the thylakoid?
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease? What effect would cyanide have on ATP synthesis?

- Figure 7.12 Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease? What effect would cyanide have on ATP synthesis?arrow_forwardDescribe the role of each of the membrane proteins shown in the picture below. Think about what is happening to the electrons and describe how energy is transformed as electrons move along the chain. Part of this involves the formation of the proton gradient. The other part is the explanation of the energetics of electron transport that you investigated above. In other words, the reason that electrons always flow from complex I to complex III to complex IV to oxygen.arrow_forwarda) At the organelle/molecular level inside a mitochondrion, wWhy do cells engaged in aerobic cellular respiration need O2? At what points during aerobic cellular resp is CO2 released? b) O2 and CO2 do not dissolve in water easily but cells must be moist to have functional phospholipid bilayers. For air breathers, moist lungs might collapse and stick together so what prevents this? c) Aquatic animals contend with the relatively lower O2 levels in water, but at least they don’t have to deal with ventilating lung. Complex gills like in fish maximize O2 exchange with a counter-current system ensuring there is always a gradient between the water and the blood. How does this ensure there is always a gradient between the water and the blood? (many people mix this up so think carefully)arrow_forward
