BSCI330 Exam #1 Questions With
Correct Answers
Light Microscopy - CORRECT ANSWER✔✔-can see large scale structures
| | | | | | | | |
such as mitochondria and bacteria (being the smallest it goes)
| | | | | | | | |
adv. cheaper, do not have to wet mount
| | | | | | |
disadv. resolution is not as good as it could be, magnification also not
| | | | | | | | | | | | |
great
Electron Microscopy - CORRECT ANSWER✔✔-electrons replace light in
| | | | | | | |
microscopy
adv. better resolution due to wavelength, higher magnification
| | | | | | |
disadv. not as cheap, fix the cells rather than examine living
| | | | | | | | | |
Scanning Electron Microscopy - CORRECT ANSWER✔✔-images the
| | | | | | |
things on the outside of the cell
| | | | | |
,Transmission Electron Microscopy - CORRECT ANSWER✔✔-internal
| | | | | |
structures of the cells | | |
Flow Cytometry - CORRECT ANSWER✔✔-adds fluorescent labels to
| | | | | | | |
measure specific biomolecules and ions
| | | |
can sort molecules based on size, shape and internal features and
| | | | | | | | | | |
architecture
Four Building Blocks of the Cell - CORRECT ANSWER✔✔-carbs/sugar
| | | | | | | |
lipid/fatty acids |
nucleotides
amino acids |
Subunit of each of the building blocks - CORRECT ANSWER✔✔-
| | | | | | | | |
sugar....polysaccharides
lipids/fatty acids....lipids, fats
| |
amino acids...proteins
|
nucleotides...nucleic acids |
Glycosidic Bonds - CORRECT ANSWER✔✔-link between two sugar
| | | | | | | |
molecules
, Phosphodiester Bonds - CORRECT ANSWER✔✔-bonds between | | | | | |
nucleotides in DNA | |
Peptide Bonds - CORRECT ANSWER✔✔-bonds between protein and
| | | | | | | |
amino acids |
Carbohydrates |
- function
|
-structure
-linkages - CORRECT ANSWER✔✔-function: main energy source
| | | | | |
structure: sugars, long chain usually but can be made into rings
| | | | | | | | | |
linkages: in rings | |
up --> beta, down --> alpha, labeled clockwise starting with the O in the
| | | | | | | | | | | | | |
ring
we cannot digest beta linkages of cellulose, but can digest alpha linkages
| | | | | | | | | | |
of starch
| |
Lipids
