The maximum yield of ATP per molecule of glucose in eukaryotic cells is 36 or 38 ATP. In prokaryotic cells, the maximum yield is 38 ATP.

a. From what you know about prokaryotes and eukaryotes, suggest why there is a difference in maximum ATP production.
b. The yield of ATP varies in eukaryotes from 36 to 38 ATP. Why is there a variation?
c. Why is ATP yield clarified with "maximum"?

Final Answer:

a. The difference in maximum ATP production between prokaryotic and eukaryotic cells can be attributed to variations in cellular structures, such as the presence of membrane-bound organelles like mitochondria in eukaryotes.

b. The variation in ATP yield in eukaryotes, ranging from 36 to 38 ATP, is influenced by factors like the efficiency of electron transport chain components and the transport of protons across mitochondrial membranes.

c. "Maximum" is clarified in ATP yield to account for the fact that cellular conditions and efficiency can influence the actual production, and variations may occur due to factors such as the efficiency of cellular respiration components.

Step-by-step explanation:

a. Difference in ATP Production: The distinction in maximum ATP production arises from the structural disparities between prokaryotic and eukaryotic cells. Eukaryotes possess membrane-bound organelles like mitochondria, which play a crucial role in ATP synthesis through cellular respiration. Prokaryotes lack these organelles and produce ATP in the cell membrane.

b. Variation in ATP Yield in Eukaryotes: The ATP yield in eukaryotes varies due to factors influencing cellular respiration. Variations in the efficiency of components of the electron transport chain and the transport of protons across mitochondrial membranes can impact the final ATP production.

c. Clarification of "Maximum": The term "maximum" is specified in ATP yield to acknowledge that actual ATP production may vary under different cellular conditions. Factors like the efficiency of cellular respiration components, substrate availability, and environmental conditions can influence the actual ATP output. The range (36 to 38 ATP) accounts for these variables.
