Question

two key reactants of cellular respiration, glucose and oxygen gas, are represented by the chemical models below. the models show the types of atoms in the molecules and the way the atoms are arranged.

complete the table to show the types of atoms found in each reactant.

type of atom	glucose	oxygen
carbon (c)
oxygen (o)

Explanation:

1. For glucose: The chemical model shows gray (H), black (C), and red (O) atoms, so all three atom types are present.
2. For oxygen: The chemical model only shows red (O) atoms, so only oxygen is present.

Answer:

Type of atom	Glucose	Oxygen
carbon (C)	✅	❌
oxygen (O)	✅	✅
