BIO 150 CELLULAR RESPIRATION QUESTIONS AND VERIFIED ANSWERS

How can cells still produce ATP if there is no oxygen available?

Cells can still produce ATP via glycolysis is they can keep regenerating
NAD+




Describe the preparatory phase of glycolysis.


Give this one a try later!


Glycolysis begins with the addition of 2 ATP molecules. 2 high energy
phosphates (one from each ATP) are added the 6-carbon molecule
glucose, producing a 6-carbon molecule with 2 phosphates.

, How are fats catabolized?


Give this one a try later!


Fatty acids are converted to acetyl CoA by beta oxidation. This requires
oxygen.




What are the 2 different ways in which ATP is produced?


Give this one a try later!


Substrate-level phosphorylation: an enzyme transfers a P from an organic
substrate molecule to ADP (happens early in cellular respiration)
Oxidative phosphorylation: energy from transferring electrons is used to
create a proton gradient. Kinetic energy from proton diffusion down the
gradient is converted to the chemical energy of ATP.




What is the theoretical yield of ATP in aerobic respiration?
