Mississippi Science FB.2.6
The Standard
- FB.2
- Students will demonstrate an understanding of the structure and interactions of matter and how the organization of matter supports living organisms.
Explain the role of the major biomolecules (carbohydrates, proteins -including enzymes, lipids, and nucleic acids) to the survival of living organisms.

What This Standard Means
What Students Need to Do
- Students explain how carbohydrates supply energy, lipids build membranes and store energy, proteins build cell parts and act as enzymes, and nucleic acids hold instructions. They connect each job to a cell's survival.
What Mastery Looks Like
- Given four cell needs, students match sugar to quick energy, a lipid to a membrane, DNA to protein instructions, and an enzyme to a reaction. They explain that an enzyme can help with another reaction because it is not used up.
Common Misconceptions
- Students may think enzymes are used up in reactions or that every protein is an enzyme. Some think DNA supplies energy, or that fats have no useful role in cells.
How to Assess It
- On an exit ticket, list four cell needs: quick energy, a faster reaction, a membrane, and instructions for making proteins. Ask students to name the biomolecule for each and explain one match.

Ways to Teach It
Give pairs paper cutouts of a sugar chain, enzyme, membrane lipid, and DNA strand; have them build a chart showing each cell job.
Ask, 'Why might a cell with plenty of food still struggle if its enzymes stopped working?' Have students write two sentences.
Label four corners with biomolecule names; read job cards such as 'speeds digestion' and 'stores genetic instructions' for students to sort.
Compare a sports drink label with a peanut butter label; have students identify carbohydrates and fats, then explain each nutrient's energy role.
