Which statement below regarding ionic compounds is FALSE? Question 5 options: Ions are held together by shared pairs of electrons. Oppositely charged ions collect together in part because isolated ions are not stable. Oppositely charged ions arrange themselves to minimize repulsions and maximize attractions. The energy associated with an ionic bond is a form of electrostatic potential energy. The net charge of an ionic compound is zero. Which statement regarding a pi-bond between two carbon atoms is correct? Question 6...

Which of the following statements about free radicals is incorrect? They are a by-product of oxygen-consuming redox reactions. They can disrupt covalent bonds in biomolecules. Superoxide catalase is one of the specific enzymes that can provide protection from their harmful effects. Their unpaired electron makes them extremely reactive. OB vitamins provide protection from their harmful effects.

Which statement is FALSE regarding flavoproteins? A) They may contain either FMN or FAD. B) The reduction potential of the flavin will depend on the amino acids in the polypeptide chain. C) They will need at least two substrates in order to function as enzymes. D) They are always integral membrane proteins. E) Most flavoproteins in electron transport have a lower reduction potential than coenzyme Q. Please explain why C is correct and D is incorrect. Thanks!

Which statement among A-D is false regarding animal viral infections? A. Uncoating refers to the process of viral exit from the host cell. B. Depending on the virus type, assembly of viruses may occur in the nucleus or cytoplasm. C. Budding is a mechanism of virus exit that leads to acquisition of the envelope around the viral particles. D. Endosome formation is a mechanism that allows for the viral genome to be freed from the capsid. none of A-D are...

mestion Completion Status: Why did I suggest that the secret to life is electrons and protons? A. Because redox reactions are necessary for all of the reactions in live cells and these redox reactions require both H+ and electrons B. Because electrons carry a negative charge and protons have a positive charge C. Because most (not all) cells need electron transport and H+ gradients to make ATP D. Because electrons are necessary for the electrical responses of the cell (like...
