Why do eukaryotes generate only about 36 ATP per glucose in aerobic respiration but prokaryotes may generate about 38 ATP?
A)eukaryotes have a less efficient electron transport system.
B)eukaryotes do not transport as much hydrogen across the mitochondrial membrane as prokaryotes do across the cytoplasmic membrane.
C)eukaryotes must shuttle pyruvate across the mitochondrial membrane by active transport.
D)eukaryotes do not completely oxidize glucose in their respiration reactions.
E)prokaryotes possess an alternate to the Krebs cycle that generates more reduced electron.carriers.

Question

Quizplus · Accepted Answer

Eukaryotes must use energy to transport pyruvate into mitochondria for aerobic respiration, which slightly reduces the total ATP yield compared to prokaryotes, which perform respiration in the cytoplasm and do not require this transport step.
