Which of the following reactions of electron transport liberate enough free energy to be able to drive the phosphorylation of ATP? You may assume that all reactants and products are at standard state concentrations. (Select all that apply.) 1. Two electrons are passed from two cytochrome c1 proteins to two cytochrome b proteins. 2. Electrons are passed from a flavin-containing protein through an Fe-S cluster protein to coenzyme Q. 3. Electrons are passed from NADH to a flavin-contain...

Look at the structures of the following molecules, which one do you think can diffuse most rapidly through a phospholipid bilayer ? Which one most slowly? ANS Urea (Most Rapid) and Lysine (Slowest) Which of the following statements about the mechanism of the Na+/K+ pump is correct? ANS The Na+/K+ ATPase uses energy to pump 3 Na+ outside the cell and 2 K+ inside. During electron transport, protons are pumped out of the mitochondrion at each of the major sites except for: ANS Complex I...

All Life Obeys the Same Chemical and Physical Laws: What Are They? ANS 1) Life is complex and dynamic. 2) Life is organized and self-sustaining. 3) Life is cellular. 4) Life is information-based. 5) Life adapts and evolves. How is life organized? ANS Atom -> Molecule -> Organelle -> Cell -> Tissue -> Organ -> Organ System What are functional groups of organic biomolecules? ANS Most organic molecules are derived from hydrocarbons. Hydrocarbons are carbon and hy...
