Item 1 • Released Regents Exam Living Environment Examination
1. In all living organisms, simple sugars (monosaccharides) such as glucose serve as the basic structural subunits that make up
(1) complex carbohydrates like starch and cellulose
(2) cell membrane lipid layers and steroid hormones
(3) structural muscle proteins and catalytic enzymes
(4) nuclear chromosomes made of DNA nucleotides
Biological Model Stimulus Use the structural comparison chart below to answer Questions 2 and 3.

Item 2 • Regents-Style Multiple Choice Chemical Composition & Elements
2. A sample of the monosaccharide glucose (\(C_6H_{12}O_6\)) is examined. Which statement correctly describes this molecule?
(1) It is composed of carbon, hydrogen, and oxygen atoms in an approximate 1:2:1 ratio.
(2) It contains nitrogen and sulfur atoms linked together by polypeptide bonds.
(3) It consists of long hydrocarbon chains that do not dissolve in aqueous solutions.
(4) It is an inorganic compound lacking carbon atoms in its molecular framework.
Item 3 • Constructed Response Molecular Size & Availability
3. Explain why a cell can use a monosaccharide like glucose for immediate energy, whereas a polysaccharide like starch or glycogen serves as a long-term energy reserve. Refer to the difference in their molecular structure or size.
Item 4 • Constructed Response Diverse Cellular Functions
4. Carbohydrates perform varied and essential functions within living cells. Complete the chart below by describing the primary cellular function for each named carbohydrate:
Carbohydrate & Class Specific Function in Living Cells
