Concept explainers
Introduction:
Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane which surrounds the entire cell is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane and it possess the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).

- Isotonic, hypotonic, and hypertonic IV (intravenous) fluid solutions are widely used in the healthcare setting. As a possible health care professional, you must know how each of the solutions work on the body and why they are given. a) When does each type of solution must be applied to a patient? b) What does each type of solution do the cells? Isotonic IV fluid solution Hypotonic IV fluid solution Hypertonic IV fluid solution|arrow_forwardWhich of the following classes of compounds are biological surfactants and one of the main components of cell membranes?arrow_forwardDetermine whether or not two conditions can occur simultaneously. Answer either "Yes" or "No." Hypoosmotic and Hypotonic [Select] Hypoosmotic and Isotonic [Select] Hypoosmotic and Hypertonic [Select] > <arrow_forward
- An amino acid mixture consisting of phenylalanine, glycine, and glutamic acid is to be separated by HPLC. The stationary phase is aqueous and the mobile phase is a solvent less polar than water. Which of these amino acids will move the fastest? Which one will move the slowest?arrow_forwardThe distribution of water is determined by solute concentrations. A hypertonic solution would cause a body cell to shrink in size. Both statements are true. Both statements are false. The first statement is true and the second statement is false. The first statement is false and the second statement is true. Spaced practice question: Consider a membrane protein and its chemistry. Which of the following would describe a channel protein? It is an inorganic compound. It is an example of a globular (functional) protein. It is stable when exposed to an acidic environment. It is an example of a fibrous (structural) protein.arrow_forwardWhich of the following correctly represents the volume of the extracellular space ): and what type of molecule (when ingested) will only distribute (by simple diffusion) within the extracellular space? 43. 80% of total body-water : non-polar 1/3 of total body-water : polar 80% of intracellular fluid : electrolytes 2/3 of total body-water : polar А.
