Final answer:
The location described as 'interior to the cell membrane' is topologically equivalent to the cytosol (C), and the 'exterior to the cell membrane' is equivalent to the extracellular space (E). The cytoplasm, consisting of the cytosol and cytoskeleton, has roles in cellular support and transport.
Step-by-step explanation:
The cytoplasm refers to the entire content within the cell membrane, excluding the nucleus, consisting of organelles suspended in the gel-like cytosol, the cytoskeleton, and various other molecules. The cytosol is the aqueous component of the cytoplasm where cell structures such as ribosomes are dispersed. Interior to the cell membrane indicates the location is topologically equivalent to the cytosol (C), whereas exterior to the cell membrane indicates a location equivalent to the extracellular space (E).
Two primary roles of the cytoplasm include protecting and supporting the cellular components. The cytoplasm contains the cytoskeleton, which is made up of three main types of fibers: actin filaments, microtubules, and intermediate filaments. These fibers maintain the cell's shape, allow movement within the cell, and anchor organelles in place.
The location of each of the following can be determined based on whether they are inside the cell or outside the cell:
Cytosol (C) is located inside the cell, specifically in the cytoplasm. It is a watery substance that contains organelles and other cell structures.
Extracellular space (E) is located outside the cell, beyond the plasma membrane. It refers to the area between cells or outside of multicellular organisms.
Therefore, the answers to the locations are:
Cytosol (C)
Extracellular space (E)
