Which of the following is evidence that chemical digestion occurs when food is processed in the body?

• The food gets softer and breaks into smaller pieces when chewed.

• The food is stored in the stomach.

• New molecules are formed from digested molecules.

• The food is moved by muscles in the digestive system

A student claims that eating fats helps with muscle growth. Based on your understanding of macronutrient functions, how should the student revise their claim?

• Fats are directly turned into muscle tissue.

• Fats are used for cellular respiration, not growth

• Fats are not used at all by the body.

• Fats are used as insulation and to build cell membranes.

Explain how cellular respiration depends on digestion. Provide one piece of evidence from the reading to support your answer.

Which process is responsible for converting glucose and oxygen into usable cellular energy?

• Photosynthesis

• Digestion

• Circulation

• Cellular respiration

Compare what happens to proteins and carbohydrates once they are broken down. State how each are used in the body? Carbohydrates: Proteins:

Using the images above, select which statement best explains why fats provide longer-term energy than sugars?

• Fats are smaller than sugars.

• Fats are easier to digest.

• Fats are larger molecules and contain more stored energy in their bonds.

• Fats do not enter the bloodstream.

Identify the molecule that cannot pass through the membrane. ________________________
