Question

cellular respiration in total can produce up to atp molecules per glucose molecule.

Explanation:

Step1: Recall cellular respiration facts

Cellular respiration has multiple stages. Glycolysis, the citric - acid cycle, and oxidative phosphorylation all contribute to ATP production.

Step2: Know ATP yield

Through these processes, up to 38 ATP molecules can be produced per glucose molecule in prokaryotes and about 30 - 32 ATP in eukaryotes. Considering the general upper - limit statement in the question, we take the higher value for prokaryotes.

Answer:

38
