ECU BIO 1050 BUNNELL EXAM 2
QUESTIONS AND ANSWERS
what is the by-product of photosynthesis is important in altering the atmosphere of the
earth so that aerobic organisms could evolve? - Correct Answers -oxygen
a green plant can carry our photosynthesis if given nothing more than: - Correct
Answers -water, light and air
potenital energy - Correct Answers -is contained in matter placed in certain positions or
arrangements
when ATP is hydrolyzed to ADP, what happens? - Correct Answers -one phosphate is
removed
a pigment that reflects all wavelengths of visible light appears - Correct Answers -white
when someone puts their contact lenses into their eyes they use saline solution. this
doesn't burn because the solution is - Correct Answers -isotonic
every time a source of energy is converted from one form to another - Correct Answers
-some of the energy is converted to heat, which is one of the least usable forms of
kinetic energy
the net movement of molecules from locally concentrated regions to uniform
distributions is the best described as - Correct Answers -diffusion
when electrons transfer their energy to help pump protons across the membrane
against their concentration gradient in the mitochondria is called - Correct Answers -
active transport
the statement that best describes the relationship between respiration and
photosynthesis - Correct Answers -photosynthesis stores energy in complex organic
molecules, while respiration releases it
Around campus there are purple and gold pansies (flowering plants) representing ECU's
colors. What is occurring in the petals of the purple flowers? - Correct Answers -yellow
light is being absorbed the purple light is being reflected
, Photosynthesis is the process by which plants, some bacteria, and some protistans use
the energy from sunlight to produce sugar, which________ converts to ATP, the "fuel"
used by all living things - Correct Answers -cellular respiration
what is NOT a form of kinetic energy - Correct Answers -a covalent bond linking
phosphate molecules
Life gains most of its energy from: - Correct Answers -sunlight
what is NOT a product of photosynthesis - Correct Answers -carbon dioxide
the movement of H+ into the stomach is accomplished through - Correct Answers -
active transport
a unique characteristic of mitochondria is that they are inherited from the female parent
only. what is the correct explanation for this phenomenon? - Correct Answers -male
sperm cells have mitochondria, but because the sperm contributes DNA but no
cytoplasm, no mitochondria are passed to the egg at fertilization
what is NOT correct about fermentation - Correct Answers -all of the above are correct
the primary function of molecular membranes is the transport of ions and molecules in
and out of cell-transport is directional and selective. the moving of molecules from the
areas of high concentration to low concentration to gain energy is described as - Correct
Answers -passive transport
what role does O2 play in aerobic respiration - Correct Answers -it is the final electron
acceptor at the end of the electron transport chain
Animal cells have "counters" that keep track of how many times a cell has divided.
These counters are called: - Correct Answers -telomeres
Sex cells having the ___________ number of chromosomes are called ____________.
- Correct Answers -haploid; gametes
In any DNA molecule, the number of guanine bases will: - Correct Answers -always be
equal to the number of cytosine bases
eukaryotic cells can divide by - Correct Answers -both mitosis and meiosis
the division of cytoplasm during cell division is referred to as - Correct Answers -
cytokinesis
prokaryotic cells generally have a single circular chromosome attached to - Correct
Answers -the cell membrane
