Final answer:
The statement regarding cytosol being full of various substances is true. It consists mostly of water but also contains enzymes, nutrients, ions, and other molecules that support cellular function and structure.
Step-by-step explanation:
The statement that cytosol is brimming with stuff is true. Cytosol is a complex mixture that forms the matrix of the cell's cytoplasm and is crucial for cellular function. It consists of water, enzymes, nutrients, ions, and various other molecules. The enzymes in cytosol are integral for catalyzing cellular chemical reactions, while dissolved ions like K+ and Na+ help maintain the cell's internal environment. The cytosol contains a semi-solid consistency due to its protein content, which can be up to 70 to 80 percent water, yet has structure provided by the cytoskeletal proteins. Moreover, it is a site for various metabolic processes including glycolysis, where glucose is broken down to release energy. Cellular components such as vacuoles, ribosomes, and other organelles are suspended within the cytosol, where they perform their respective roles in the cell's metabolism.
