11) 11) The smallest cell structure that would most likely be visible with a standard (not super-resolution) research-grade light microscope is A) a ribosome. B) a microfilament. C) a microtubule. D) a mitochondrion. E) a nuclear pore. 12)_ 12) What do the cell walls of plants and the extracellular matrix of animal cells have in common? A) Their proteins are made by free cytoplasmic ribosomes. B) They have functional connections with the cytoskeleton inside the cell. C) They are largely composed of phospholipids and glycoproteins. D) They form rigid structures that provide structural support for cells but limit their expansion. E) They limit the passage of small molecules 13) 13) ECM proteins are made by ribosomes in which part of a eukaryotic cell? A) cytoplasm B) nuclear envelope C) rough ER D) Golgi apparatus E) mitochondria 14) Cyanide binds with at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the cyanide will be found within the A) mitochondria. B) lysosomes E) endoplasmic reticulum. 15) Which of the following types of molecules are the major structural components of the cell membrane? A) nucleic acids and proteins B) glycoproteins and cholesterol C) proteins and cellulose D) phospholipids and proteins E) phospholipids and cellulose 16) A protein that spans the phospholipid bilayer one or more times is 16) A) a transmembrane protein. B) a peripheral protein. C) a glycoprotein. D) an integral protein. E) an integrin.Explanation / Answer
Answer.
11). D. a mitochondrion
12). B) They have functional connections with the cytoskeleton inside the cell.
13). C. Rough ER
14). A. Mitochondria
Explanation. Cyanide arrest the cellular respiration by binding with mitochondria.
15). D) phospholipids and proteins
Explanation. Cell membrane consists of lipid Bayer, in which proteins are embedded.
16). D. An integral protein.
Explanation. All transmembrane proteins are IMPs, but not all IMPs are transmembrane proteins
