While eukaryotic cells are generally larger than prokaryotic cells, metabolic requirements place upper limits on how large eukaryotic cells can become. Which of the following statements does not accurately describe this? As multicellular organisms grow in size, they do not have larger cells; rather, they have a larger number of cells. As a cell increases in size, the surface area grows faster than volume. If a cell is too large, there will not be enough surface area for the exchange or elimination of oxygen, nutrients, and wastes. The surface area to volume ratio must remain as large as possible

Which of the following provides the most likely explanation for the limiting factor of a cell's size? A B с D As the cell size increases, its volume increases while its surface area does not.

Describe the general functions of the following in a eukaryotic cell: the plasma membrane, cytoplasm, DNA, ribosomes, organelles, and cytoskeleton.
The plasma membrane __________. a. surrounds the cytoplasm b. separates the nucleus from the cytoplasm c. separates the cell interior from the environment d. both a and c
It is believed that one of the earliest steps needed in the creation of the first cells was the creation of a membrane. Over time, membranes evolved to perform several vital metabolic processes. Identify and explain how specific membrane components are necessary for one important cellular process, metabolic process, or homeostatic process.

Which of the following statements are correct about how the complex biological matrix of the cell may affect protein folding, stability and function (select all that appy)? A. ATP tends to "bounce" along the surfaces of many proteins without forming a stable complex B. Proteins make up approximately 30% of the total volume of the cytoplasm in a typical cell C. Compettition between drug molecules and metabolites in the cytoplasm may cause unexpected drug side effects not seen with individual proteins in solution. D. Large protein complexes move faster through the cytoplasm than small metabolites. E. Complex intercations between proteins in the cell may significantly destabilize a protein compared to the isolated protein in water
