• Total Fat

• Sodium

• Total Carb (carbohydrates)

• Protein

Which table correctly identifies the function of each type of RNA?

• Type of RNA: Transfer RNA - Brings amino acids to growing polypeptides in ribosomes

• Type of RNA: Ribosomal RNA - A component of ribosomes that helps catalyze protein synthesis

• Type of RNA: Messenger RNA - Carries genetic information from DNA to ribosomes

Which pair of statements best compares the primary functions of the carbohydrate chitin and the protein chitinase?

• The chitin in the exoskeleton breaks down for energy to be used by insects.

• The chitin in the exoskeleton provides support and protection for insects.

• The chitinase provides insulation for insectivorous bats.

• The chitin in the exoskeleton provides insulation for insects.

• The chitinase stores genetic material for insectivorous bats.

Which statements best compare a function of proteins and lipids in a human cell?

• Proteins provide energy for cellular processes. Lipids catalyze chemical reactions inside the cell.

• Proteins catalyze chemical reactions inside the cell. Lipids allow for the transport of certain molecules into and out of the cell.

• Proteins allow for the transport of certain molecules into and out of the cell. Lipids store genetic information for cells.

• Proteins store genetic information for cells. Lipids provide energy for cellular processes.

Which statements best compare the function of an ATP molecule to a DNA molecule?

• ATP carries and transmits the genetic information of organisms.

• DNA carries and transmits the genetic information of organisms.

• DNA serves as a biological catalyst that speeds up the rate of chemical reactions.

• ATP serves as a biological catalyst that speeds up the rate of chemical reactions.

• ATP provides energy for chemical reactions in the cell.

A student makes a Venn diagram to compare the functions of carbohydrates and lipids.

• Hormone production

• Structural support of cell walls

• Energy storage

• Catalyst for chemical reactions

Which list correctly matches the functions to the types of carbohydrates?

• Energy: cellulose and chitin

• Structure: cellulose and chitin

• Energy: glycogen and starch

• Structure: glycogen and starch

• Energy: chitin and glycogen

Transmembrane proteins span the width of cell membranes. Four types of transmembrane proteins are shown in a section of cell membrane. Although these proteins have different specific functions, they all —

• stop chemical reactions within the cell

• synthesize molecules that signal other cells

• help the cell interact with its external environment

• remove large waste particles from the cytoplasm of the cell

What do monomers do?

• Bond to make a polymer
• Create essential proteins
• Stores energy
• Splits to make more cells
