Question

carbon, hydrogen, and oxygen atoms make up glucose and oxygen gas, which are the reactants of cellular respiration. carbon, hydrogen, and oxygen atoms also make up carbon dioxide gas and water, which are the products of cellular respiration.
for every molecule of glucose (c6h12o6) that goes into cellular respiration, the process requires 6 molecules of oxygen gas (o2).
complete the table.

type of atom	number of atoms in 1 molecule of glucose	number of atoms in 6 molecules of oxygen	total number of atoms in reactants
c	6	0
o		12

Explanation:

Step1: Determine H atoms in glucose

The formula of glucose is $C_{6}H_{12}O_{6}$, so there are 12 H atoms in 1 molecule of glucose.

Step2: Calculate total H atoms in reactants

Since there are no H atoms in oxygen, the total number of H atoms in reactants is 12.

Step3: Calculate total C atoms in reactants

There are 6 C atoms in 1 molecule of glucose and no C atoms in oxygen, so the total number of C atoms in reactants is 6.

Step4: Calculate O atoms in glucose

In 1 molecule of glucose $C_{6}H_{12}O_{6}$, there are 6 O atoms.

Step5: Calculate total O atoms in reactants

There are 6 O atoms in glucose and 12 O atoms in 6 molecules of oxygen. So the total number of O atoms in reactants is $6 + 12=18$.

Answer:

Type of atom	Number of atoms in 1 molecule of glucose	Number of atoms in 6 molecules of oxygen	Total number of atoms in reactants
C	6	0	6
O	6	12	18
