SCIENTIFIC INQUIRY In the 1930s, some physiciansprescribed low doses of a compound called dinitrophenol(DNP) to help patients lose weight. This unsafe method wasabandoned after some patients died. DNP uncouples thechemiosmotic machinery by making the lipid bilayer of theinner mitochondrial membrane leaky to H+. Explain howthis could cause weight loss and death.
the concentrated charge in the intermembrane space leaves through a. the H+ pumps b. ATP synthasec. the outer membraned. the Krebs cyclee. membrane pores

Imagine that you are working with isolated mitochondria and you manage to double the ratio of protons outside to protons inside. In order to maintain the overall Gat its original value (whatever it is), how would you have to change the mitochondria membrane potential?
Which of the following is not produced by an animal muscle cell operating under anaerobic conditions? a. heat b. pyruvate c. PGAL d. ATP e. lactate f. oxygen
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. Why do you suppose that the proton-motive force in chloroplasts can depend more on pH than mitochondria can? Why is () less in chloroplasts than in mitochondria?
A molecule that donates electrons becomes ________, and the one that accepts the electrons becomes ________. a. reduced; oxidized b. ionic; electrified. c. oxidized; reduced d. electrified; ionic
Electronegativity is the ability for an atom or molecule to attract electrons (see chapter 2). Considering the components of theelectron-transport chain, with protein I being the beginning of the chain and protein IV the end of the chain, which end has thehigher electronegativity?

What chemical property of phospholipids is key to the formation ofthe cell membrane?a. The positively charged nitrogen atomb. The covalent bond between the phosphate and the glycerolc. The kink in the fatty acid taild. The hydrophilic head and hydrophobic tails
A 75 kg person doing light work requires about 3000 kcal of food energy perday, 40% of which is actually used by the body’s cells. (The other 60% is lostas heat and in waste products.) Before being used by the cells, effectively allof this energy is stored in ATP, which is then cleaved into ADP and PO3−2 , with the release of 12.5 kcal per mole of ATP.(a) How many moles of ATP are turned over per day in this fashion? Whatmass of ATP does this correspond to? (The molecular weight of ATP is507 g/mol.)(b) The body actually contains approximately 5 g ATP. Estimate the averagerecycle time for an ATP molecule. You see that it is much more efficientto reuse ADP rather than to synthesize it de novo (from scratch).
