Question

in a chemical process such as cellular respiration, the reactants and the products have the same number and types of atoms. but the arrangement of these atoms changes. this process can release energy.
look at the models of molecules involved in cellular respiration. focus on the chemical bonds, or connections between atoms, in each reactant and each product.
which types of bonds are in each molecule? complete the table to describe the reactants and the products.

Explanation:

• Glucose:
• It has carbon - carbon bonds (as it is a chain of carbon atoms).
• It has carbon - oxygen bonds (as part of its structure).
• It has oxygen - hydrogen bonds (in the hydroxyl groups).
• Oxygen:
• It has oxygen - oxygen bonds (as \(O_2\) molecule).
• Carbon dioxide:
• It has carbon - oxygen bonds (in \(CO_2\) molecule).
• Water:
• It has oxygen - hydrogen bonds (in \(H_2O\) molecule).

Answer:

Chemical bonds	Glucose	Oxygen	Carbon dioxide	Water
an oxygen atom connected to another oxygen atom		✔
a carbon atom connected to an oxygen atom	✔		✔
an oxygen atom connected to a hydrogen atom	✔			✔
