Our bodies can burn both Glucose (sugars) and Lipids (fats) to get energy ATP. Use the chemical equations for both using Glucose and using Lipids to answer the following question.


a. Choose all the true responses about the cellular respiration of Glucose vs Fat. Hint: there are 6.
Both glucose and fat contain, Carbon, Hydrogen and Oxygen in their chemical structure
Both equations require 6O2 to make energy
Both equations have 16H2O molecules as a product
Both equations give off CO2 (Carbon Dioxide)
Both molecules can be metabolized to produce ATP
Both equations produce 16CO2(Carbon Dioxide)
Burning Glucose only uses 6O2 gas molecules as a reactant
Burning Fat only uses 6O2 gas molecules as a reactant
In both equations, the number of Carbon going in equals the number of Carbon coming out.
Burning Fat requires more O2 (Oxygen gas) molecules to breakdown because it has so many more bonds to break in it's structure
Glucose and Fats have the same number of C, H and O in their chemical structure.
Glucose has more bonds to break to get ATP than fat does.

True statements (6):

1. Both glucose and fat contain Carbon, Hydrogen and Oxygen in their chemical structure.
2. Both equations give off CO2 (Carbon Dioxide).
3. Both molecules can be metabolized to produce ATP.
4. Burning Glucose only uses 6 O2 gas molecules as a reactant. (per one C6H12O6 molecule)
5. In both equations, the number of Carbon going in equals the number of Carbon coming out. (atoms are conserved)
6. Burning Fat requires more O2 molecules to break down because it has many more bonds (more H and C) to oxidize.

Quick rationale and equations used:
- Glucose respiration: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O (+ ATP).
- A common fat example (palmitic acid) oxidation: C16H32O2 + 23 O2 → 16 CO2 + 16 H2O (+ ATP).

From these, carbons are conserved (in = out), both give CO2 and can yield ATP, glucose uses 6 O2 per molecule while a long fatty acid requires many more O2 (e.g., 23 for C16), and fats contain the same element types but different counts of C, H, O than glucose.
