1 molecule of glucose makes _ atp (anaerobic)
1 molecule of glucose makes _ atp (aerobic)
1 molecule of creatine phosphate makes _ atp
adp + p --> atp _ energy
atp --> adp + p _ energy

options:
38
2
1
releases
requires

Explanation:

Analyze anaerobic glucose metabolism

Using the Muscle Contraction Energetics knowledge point
Anaerobic glycolysis breaks down one glucose molecule into lactic acid, yielding a net of 2 ATP molecules.
Therefore, the correct label is "2".

Analyze aerobic glucose metabolism

Aerobic respiration completely oxidizes one glucose molecule via glycolysis, the citric acid cycle, and the electron transport chain, yielding approximately 36 to 38 ATP molecules.
Therefore, the correct label is "38".

Analyze creatine phosphate metabolism

Creatine phosphate transfers its high-energy phosphate group directly to ADP to regenerate ATP in a single-step reaction.

$$ \text{Creatine Phosphate} + \text{ADP} ightarrow \text{Creatine} + \text{ATP} $$

This pathway yields 1 ATP molecule per molecule of creatine phosphate.
Therefore, the correct label is "1".

Analyze ATP synthesis energetics

The synthesis of ATP from ADP and inorganic phosphate (\(\text{P}_i\)) is an endergonic reaction.

$$ \text{ADP} + \text{P}_i ightarrow \text{ATP} $$

This process stores energy and thus requires energy input.
Therefore, the correct label is "requires".

Analyze ATP hydrolysis energetics

The breakdown of ATP into ADP and inorganic phosphate (\(\text{P}_i\)) is an exergonic reaction.

$$ \text{ATP} ightarrow \text{ADP} + \text{P}_i $$

This process releases stored chemical energy to power cellular work.
Therefore, the correct label is "releases".
