Considering the frequency of non-polar bonds in each type of molecule, which type of molecule
should store the most energy (assuming you have the same mass of each)? - Answer Lipids
If energy levels are HIGH in a cell (there is lots of ATP), which of the following can occur?
(Choose ALL correct answers) Hint - see Fig. 9.3. - Answer acetyl CoA can be used in pathways
that produce fatty acids
some of the intermediates of the Krebs cycle can be used in pathways that produce amino acids

answers) (Refer to Fig. 27.7 and text on pages 546-547) - Answer mitochondria have their own
DNA which is circular
mitochondria have ribosomes which are different in structure than those in the cytoplasm
It is advantageous for glycolysis to slow when cellular energy levels are ________. It therefore
makes sense that the glycolysis enzyme, phosphofructokinase, is allosterically ________ by ATP.
- Answer High;inhibited
What is the main goal of the process called "fermentation"? - Answer It allows a cell to oxidize
cytoplasmic NADH to NAD+ so that glycolysis can proceed
Which is true about fermentation how much ATP/glucose can be made? - Answer
fermentation produces much LESS ATP than aerobic cellular respiration
