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.
