BIO 1108 GEORGIA SOUTHERN TEST 2 QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) |ALREADY GRADED A+||BRAND NEW
simplest definition of life - (ANSWER)-ability to replicate (utilize and pass on genetic info)
-ability to carry out metabolism (acquire and transform energy)
Types of metabolism - (ANSWER)-energy source + carbon source (photoautotroph vs.
chemoheterotroph)
-role of oxygen in metabolism (obligate, facultative , obligate)
Photoautotrophs - (ANSWER)organisms that carry out photosynthesis. Using energy from sunlight,
carbon dioxide and water are converted into organic materials to be used in cellular functions such as
biosynthesis and respiration.
Chemoheterotrophs - (ANSWER)An organism that must consume organic molecules for both energy and
carbon.
obligate vs facultative - (ANSWER)facultative anaerobe is an organism that makes ATP by aerobic
respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if
oxygen is absent.
An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die
in the presence of oxygen.
characteristics of life - (ANSWER)metabolism/homeostasis, organization (cell structure), reproduction,
growth, reponse, adaptation.
metabolic activity only occurs... - (ANSWER)after taking over process of another organism
Function of glycoproteins - (ANSWER)cell-cell interactions
signal transduction
cell proliferation
cell differentiation

apoptosis
prions - (ANSWER)misfolded proteins, contain no nucleic acid
domain bacteria-kingdom Eubacteria - (ANSWER)-chlamydias
-spirochetes
-cyanobacteria
-proteobacteria
-gram positive bacteria
Proteobacteria - (ANSWER)Most diverse bacterial lineage, gram negative, earliest branch, (E. Coli)
Chlamydias - (ANSWER)-low peptidoglycan
-lacks enzymes
-STDs/Blindness
Spirochetes - (ANSWER)-helical heterotrophs
-endocellular flagella
-syphilis and lyme disease
cyanobacteria - (ANSWER)-photoautotrophs (phytoplankton/ O2)
-antiviral, antibacterial, antifungal and anticancer activities
Gram-positive bacteria - (ANSWER)Bacteria that have simple cell walls with much peptidoglycan.
endospores
(staph/strep)
