1)NADH is made from NAD+ by a)An oxidation-reduction reaction b)Oxidative phosphorylation c)A proton gradient d)A dehydration reaction e)Substrate-level phosphorylation 2. The energy used to make ATP via substrate-level phosphorylation is from a(n) a)Electron gradient b)Reduction reaction c)Phosphorylated molecule d)ADP molecule e) Protein gradient 3. Which of the following molecules, as written, is in its reduced form? a)NADH b)O2 c)NAD+ d)FAD e)CO2 4. Cellulose is a good structural molecule because a)The molecule is amphipathic, allow it to interact with water and nonpolar substances b)The bonds between the monomers are difficult to break, increasing its stability c)It is a mix of carbohydrate and protein, allowing it to form multiple types of bonds

What is (are) the product(s) that are transferred into the electron transport chain from the citric acid cycle? A) NAD' and FAD B) NADH, FADH,, and H C) NADH, FADH,, H*, and ATP D) ATP E) NAD', FAD, and ATP

During oxidatative phosphorylation, the role of oxygen is to: a) run through the turbine to spin it so that the energy can be used to make ATP b) keep glycolysis running so that fermentation can continue c) bind with the carbons from glucose to make carbon dioxide to be expelled from the body d)  form a gradient to provide energy to run the electron transport chain e) accept low energy electrons from the bottom of the electron transport chain so that it can continue to run

When NAD+ accepts electrons during a glycolysis reaction, this is an example of a _____ reaction. A)protonation B)phosphorylation C)dehydration D)redox
