Question
the cell wall d. c. Actually, the function of the rough endoplasmic reticulum is not performed in bacterial cells 8. If you had a compound light microscope with two 10X oculars and a single 50X objective, and used it to look at a cell that was 4 m long, the cell would appear to be: a. 4um long b. 1 mm long c. 2 mm long d. 200 m long 9. Scanning electron microscopy (SEM) is better than transmission electron microscopy (TEM) because: a. the resolving power of SEM is greater b. only thin sections of specimens may be examined in SEM. c. SEM uses fluorescent lenses instead of electromagnetic lenses. d. the magnified images in SEM appear three dimensional. 10. Acid-fast staining is a useful method of preparing clinical specimens for microscopy because a. the acid kills all the bacteria on the slide b. "acid-fast" means the same as "Gram positive" c. only a few species are acid-fast, but this small group includes important species d. it is not a differential staining method, so it requires only one staining reagent 11. Cells use each of the following mechanisms for generating ATP from ADP +P except a. autophosphorylation b. photophosphorylation c. substrate level phosphorylation d. oxidative phosphorylation 12. The electrochemical proton gradient made by the electron transport system is used to make ATP and to drive:Explanation / Answer
Answer:
1) If you had a compound light microscope with two 10X oculars and a single 50X objective, and used it to look at a cell that was 4um long, the cell would appear to be: 2mm long (magnification = 50*10 = 500X, so size will be 4uM * 500 = 2000uM = 2mm)
2) Scanning electron microscopy (SEM) is better than transmission electron microscopy (TEM) because: the magnified images in SEM appear three dimensional
3) Acid-fast staining is useful method of preparing clinical specimens for microscopy because only a few species are acid-fast, but this small group includes important species.
4) Cells use each of the following mechanism for generating ATP from ADP + P except: autophosphorylation
