What is the best description of the role of NADH in a cell? Select one: a. A waste product b. A carbohydrate, which stores energy in its many C-C bonds c. A protein that spins allowing hydrogen ions to pass through d. An electron carrier e. A molecule used to directly "power" most of a cell's work, for example active transport and myosin to make muscles to contract. What does the Krebs cycle accomplish? Select one: a. Breaks down larger carbon into smaller carbon molecules b. Generates ATP c. Reduces electron carriers (think of the specific ones you know) d. All of the above

Select the statement regarding the plasma membrane that is FALSE
(if any).
Select one:
O a. All living organisms have cells with plasma membranes
O b. The phospholipid bilayer has a hydrophobic region and a
hydrophilic region.
c. Because of the plasma membrane's selectivity permeability,
a cell's interior is chemically very different from the
surroundings outside.
O d. None of the above (meaning all statements are true).
