Transmembrane proteins span the width of cell membranes. Four types of transmembrane proteins are shown in the 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 cytosplasm of the cell

Energy storage
Select the rectangle that best answers the question.
Ethan is studying how animals, like bears, hedgehogs, and frogs, hibernate during the cold winter months to conserve energy. Hibernation allows them to survive for long periods of time without needing to eat. Their bodies get nutrients and energy during hibernation by burning stored fat. In order for hibernation to work, the animal would need to eat a lot of what biomolecule first?
Carbohydrates
Lipids
Nucleic acids
Proteins
Evelyn, a biology student, drew a simple illustration to show how a protein’s structure determines its function and how it relates to the structure and function in a cell. She indicated the protein structure with an arrow. What function would the protein shown in her illustration below play in a cell?
