When a single glucose molecule undergoes glycolysis, 2 molecules of pyruvic acid are produced. The correct response is:

**2**

In cellular respiration, the most prevalent atom is hydrogen (H), followed by carbon (C), and finally oxygen (O). Therefore, the correct order from most prevalent to least prevalent is:

**H, C, O**

In cellular respiration, each glucose molecule produces 6 molecules of carbon dioxide (CO2). Therefore, when three glucose molecules undergo cellular respiration, the total number of CO2 molecules produced is:

3 glucose × 6 CO2/glucose = 18 CO2 molecules.

The correct response is:

**18**
Answered by GPT-4o mini
During cellular respiration, glucose and oxygen are converted into carbon dioxide, water, and energy. While gases like carbon dioxide and water are produced, the overall mass of the system remains constant due to the law of conservation of mass. Therefore, the weight of the insulated, sealed container will:

The correct response is:

**A 3D model shows how the different atoms are arranged, but the formula model does not.**

A 3D model provides a visual representation of the spatial arrangement of atoms in a molecule, while a formula model (like a chemical formula) indicates the types and quantities of atoms but does not convey their arrangement in three-dimensional space.
