Eukaryotic cells consist of several organelles, including Golgi complex, mitochondria, endoplasmic reticulum, flagella and cilia, chloroplast, microfilaments and microtubules, and lysosomes. The key reaction happening in the mitochondrion is cellular respiration and the key product formed is ATP. The key reaction happening in chloroplast (chlorophyll-containing organelle) is photosynthesis and the key product formed is glucose (organic compound). By photosynthesis, this organelle also results in the production of oxygen. Eukaryotic microorganisms with hydrogenosomes perform an obligate fermentative metabolism . The major reaction occurring is pyruvate oxidation, which results in the production of H 2 , acetate, and carbon dioxide (CO 2 ).

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

If a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source. Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.

If a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make? Assume no other carbon source is available. Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.

How much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA. (pathways will be provided on the exam) Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
