Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.15 Carbohydrates. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Carbohydrates: Students connect carbohydrate structure to short-term energy storage, structural support, and cell recognition, including monosaccharides, disaccharides, and polysaccharides. Rigor range: standard concept checks through honors/Pre-AP/AP-ready structure-function and biochemical data interpretation. Aligned to FreeK12Practice High School Biology Curriculum Crosswalk (NGSS/NRC Framework; CCSS Literacy and Mathematics; AP Biology enrichment; Texas TEKS Biology; Florida NGSSS/CPALMS Biology; Virginia SOL Biology; California NGSS and New York State Science Learning Standards) BIO.10.15 - Carbohydrates: Corresponding standards copied from the curriculum for skill 10.15: National: NGSS HS-LS1-6; DCI LS1.C; CCSS RST.9-10.2; AP Biology ENE-1.

Below are sample questions representative of the exercises included on this worksheet and related 10.15 Carbohydrates skill assessments:

Problem 1Difficulty: Mastery

A chromatography result shows hydrolysis products from three samples. Sample 1 produces glucose only, Sample 2 produces glucose plus fructose, and Sample 3 produces glucose plus galactose. Which conclusion is most precise?

AAll three samples must be cellulose because every carbohydrate contains galactose.

BSample 2 must be glycogen because glycogen hydrolyzes to fructose.

CSample 3 must be starch because starch hydrolyzes to galactose.

DSample 1 could be a glucose polymer, Sample 2 could be sucrose, and Sample 3 could be lactose.

Solution & Explanation:Glucose-only products fit glucose polymers such as starch or glycogen; glucose plus fructose fits sucrose; glucose plus galactose fits lactose.

Problem 2Difficulty: Mastery

A class compares starch, glycogen, and cellulose. Which general principle best explains why these glucose polymers have different biological roles?

AA molecule's biological role depends only on its total mass.

BGlucose polymers all have identical shapes and functions.

CMolecular structure, including linkage and branching, shapes biological function.

DCarbohydrates cannot be used for both storage and structure.

Solution & Explanation:Starch, glycogen, and cellulose all use glucose units, but their linkages and branching differ. Those structural differences explain storage versus support functions.

Problem 3Difficulty: Mastery

A chemical inhibitor blocks cellulose synthase in growing plant cells. Which result would most directly follow from carbohydrate structure-function relationships?

ACells would make extra glycogen because cellulose synthase makes animal storage carbohydrate.

BNew cell walls would be weaker because fewer cellulose microfibrils form.

CDNA replication would stop because cellulose is a nucleotide polymer.

DAll starch granules would instantly become cell membranes.

Solution & Explanation:Cellulose synthase helps build cellulose chains for plant cell walls. Blocking it would reduce microfibril formation and weaken new walls.
