1 INCORRECT What is the basic structural unit of the body? A) tissue B) organ C) organelle D) cell Feedback: Incorrect: An organ is comprised of two or more tissues. 2 INCORRECT Which of the following are the smallest cells? A) human ovum B) red blood cell C) white blood cell D) smooth muscle cell Feedback: Incorrect: Smooth muscle cells are larger than blood cells. 3 CORRECT Two major parts of a cell are the nucleus and _____. A) membrane B) organelle C) reticulum D) mitochondrion Feedback: Correct Answer: All cells (eukaryotic) consist of a nuclear area and the fluid and structures that surround it, the cytoplasm, enclosed by a plasma membrane. 4 INCORRECT A ribosome is an example of a _____. A) nuclear membrane B) organelle C) inclusion D) protein Feedback: Incorrect: An organelle is a structure within a cell with a known function; the ribosomes are associated with protein synthesis. 5 INCORRECT A cell membrane allows only needed substances to pass and is therefore called _____. A) permeable B) passive C) active D) selective Feedback: Incorrect: Passive membranes use no ATP and follow only physical laws. 6 INCORRECT A human cell membrane is comprised of the following except which one? A) lipids B) proteins C) carbohydrates D) nucleic acids Feedback: Incorrect: Membranes contain carbohydrate sections. 7 INCORRECT The following terms belong together except which one? A) protein B) phospholipid C) hydrophilic ends D) hydrophobic ends Feedback: Incorrect: The cell membrane has phospholipid molecules that have water soluble (hydrophilic) as well as water insoluble (hydrophobic) portions. 8 INCORRECT The following molecules freely pass through a cell membrane except which one? A) oxygen B) carbon dioxide C) amino acids D) certain lipids Feedback: Incorrect: Carbon dioxide gas diffuses freely. 9 CORRECT Hormones come in contact with the _____ molecules in a membrane. A) lipid B) rod-like protein C) globular protein D) integral protein Feedback: Correct Answer: Rod-like proteins are coiled and extend from the interior to exterior of a cell membrane and can serve as an attachment for hormones and other molecules, serving as receptor sites. 10 INCORRECT The selective movement of ions through a membrane occurs through areas called _____. A) pores B) peripheral protein regions C) channels D) receptors Feedback: Incorrect: Peripheral proteins do not usually function as channels. 11 INCORRECT The _____ proteins in a membrane function as enzymes. A) peripheral B) structural C) integral D) rod-like Feedback: Incorrect: The peripheral proteins line the inner surface of the cell membrane and act as enzymes that increase certain reaction rates. 12 INCORRECT The cells in heart muscle are often held together by areas called _____. A) desmosomes B) tight junctions C) gap junctions D) intercellular fluid Feedback: Incorrect: Gap junctions are areas of tubular channels that interconnect cardiac muscle as well as muscle in the digestive tract. 13 INCORRECT The inside lining of the digestive tract is lined with cells that are held together by _____. A) gap junctions B) tight junctions C) connective tissue D) desmosomes Feedback: Incorrect: Tight junctions are a type of intercellular junction that hold together certain cells; there is no connective tissue in the inner lining of the digestive tube. 14 INCORRECT The _____ contains enzymes that are associated with protein synthesis. A) mitochondrion B) ribosome C) lysosome D) Golgi body Feedback: Incorrect: Lysosomes contain catabolic enzymes.
