Molecule Structure Function Carbohydrates Polymers of glucose rings Protoins Polymers of amino acids Liplds Glycerol + fatty acids A student is comparing the different macromolecule types for a biology class. The student described the structure of the molecules but then must complete the table for the functions of these molecules. Which description accurately compares the functions of carbohydrates and proteins and can be used to complete the table? A) Carbohydrates and proteins can both be used for energy by the cell. Carbohydrates and proteins can both be used as enzymes by the cell. C) Carbohydrates and proteins can both be used for signaling by the cell. Carbohydrates and proteins share no common functions since their structures are different. D) B)
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
