a molecule made of carbon and oxygen atoms

the chemical reaction between oxygen and glucose that releases energy into cells

a process in which atoms rearrange to form new substances

the body system that transports molecules to and from all cells of the body

a proposed answer to a question about the natural world

the body system that takes in food and breaks it down

the ability to make things move or change

information about the natural world that is used to support or go against (refute) a claim

a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms

the body’s use of molecules for energy and growth

a group of atoms joined together in a particular way

a molecule that organisms get from the air or water around them and use to release energy

a category of large molecules that perform important functions inside living things

the process of making clear how your evidence supports your claim

the body system that takes in oxygen and releases carbon dioxide

a type of energy storage molecule made of many glucose molecules connected together

a set of interacting parts forming a complex whole

If a person is breathing normally, what could prevent him from using his body to exercise normally?

Not eating enough food, because cells need molecules from both food and air to work

What could happen if Rico's breathing gear broke during a dive and he could not breathe as much air as usual?

It would be difficult to swim, because his cells cannot work without molecules from air.

Raoul ate a meal of oats before seeing his doctor. Oats are made of mostly starch molecules. Raoul feels tired, so his doctor gave him a test and found that Raoul’s cells contained glucose molecules, but they did not contain enough oxygen molecules. Does this explain why Raoul feels tired?

Yes, his digestive system is breaking down starch molecules, but his respiratory system may not be working properly.

Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of amino acids, normal levels of oxygen molecules, and low levels of glucose molecules. Will this patient be able to exercise normally?

No, her cells need glucose to react with oxygen to release energy.

What are Chemical Reactions?

a process in which atoms rearrange to form new substances

The law of conservation of mass states that...

Matter can neither be made or destroyed

What happens to water molecules when you boil water in a pot and it escapes as steam?

The molecules speed up as the kinetic energy increases and the molecules move farther apart from one another.

What happens when heat is added to a substance?

Energy moves into the substance causing the molecules to speed up.
