Food Molecules

We said that glucose (sugar) is broken down during cellular respiration to make energy. Sugar is called a carbohydrate, but there are other food molecules, such as proteins and lipids, that can give us energy during cellular repiration.

Carbohydrates

• Commonly referred to as "sugars"

• Include things like breads, pastas, fruits.

• Sugars are easily broken down during cellular respiration

• Lots of energy is produced from carbs. That's why we feel a lot of energy after eating things like cookies and chocolate.

Multiple Choice

Which of the following is not primarily a carbohydrate?

• Banana

• Bread

• Ground Beef

• Macaroni Noodles

Proteins

• Proteins include meats, nuts, and legumes.

• Proteins are made of amino acids.

• During cellular respiration, the protein is broken back down into amino acids, which releases energy.

Multiple Choice

Proteins are made from...

• nucleic acids

• nitric acid

• citric acid

• amino acids

Lipids

• Lipids are also known as fats

• A lipid called the triglyceride is the lipid we use for energy during cellular repiration.

Multiple Choice

What form of lipids does our body use during cellular respiration to make energy

• oil

• wax

• triglycerides
