Which of the following is not a product of cellular respiration? a. CO2
b. Energy
c. C6H1206
d. H20

The only molecule in the group that is not a product of cellular respiration is C₆H₁₂O₆ (option c).

Explanation:

C₆H₁₂O₆ is the glucose molecule, which is an energetic substrate and not a product of cellular respiration.

Cellular respiration is the process by which, through the oxidation of glucose and in the presence of oxygen, energy is obtained in the form of ATP. The reaction that summarizes this process is:

                     C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)↑

As can be seen in the diagram, while glucose and oxygen are substrates of the reaction, the resulting products are CO₂, H₂O and energy.

the major parts of the digestive system:

salivary glands.

pharynx.

esophagus.

stomach.

small intestine.

large intestine.

rectum.

accessory digestive organs: liver, gallbladder, pancreas.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
