Biomolecules in the real world

Relate the structure of carbohydrates, lipids, proteins, and nucleic acids to their functions in cells.

Transfer evidence, not just familiar practice

Correctly solve different fresh variations at least 24 hours after your first correct transfer response. Reviewing the same challenge again does not count as fresh retention evidence.

Biotechnology product lab

A biotechnology team develops emergency nutrition and evaluates a new medicine. Its decisions depend on how molecular building blocks determine energy storage, membrane structure, and receptor shape.

Why this TEKS matters

Biomolecule structure explains why a ration releases energy quickly and why changing a protein's amino acid sequence can change how a medicine binds.

Challenge 1

Compare emergency rations

Recommend which ration supplies accessible short-term energy and which provides compact long-term storage.

Challenge 2

Evaluate a receptor medicine

Predict how a change to the receptor's amino acid sequence could affect the medicine's binding pocket.

Everyday life · Cleaning and health information

Health and safety at home

A detergent label warns that it can damage cell membranes, while a news report describes a virus with a nucleic-acid genome and a protein coat. Both stories require identifying molecules from their structures.

Why this TEKS matters

Recognizing monomers and molecular structures helps you interpret cleaning products, nutrition labels, and reliable health information.

Challenge 3

Interpret a detergent warning

Use the water-attracting heads and water-repelling tails to identify the membrane molecules being disrupted.

Challenge 4

Read a virus report

Distinguish the virus's genetic material from its protein coat using the described building blocks.
