BIO 212 Distance Lectures Verified Questions And
Answers With Real Solutions
a virus isn't considered to be alive because... ANS it can't carry out metabolism
cells make up ___ living things ANS all living things
coated vesicles are important in.... ANS endocytosis (active transport of molecules into the cell by
engulfing the molecule in the membrane)
interstitial fluid is found surrounding... ANS all active cells
when someone loses weight, where does that mass go? ANS exhaled as gas
plant organs are defined by ____ and animal organs are defined by___ ANS - the location at which
they are created
- function
the graph of internal conditions of an animal that is a conformer has a line with a ___ slope than that of a
regulator ANS larger (regulators have horizontal slope, slope = 0, while conformers have a diagonal
slow ~1)
there is a higher concentration of cations outside the cell than inside the cell. a cation is allowed to flow
through the membrane. this creates... ANS a positive membrane potential
enzymes... ANS - do not influence the direction of biochemical reactions
- influence the rate of biochemical reactions

uncoupler protein activity occurs when temperatures are... ANS below the lower critical temperature
an animal carrying out metabolic thermogenesis has... ANS a relatively increased PFK activity and a
reduced ATP synthesis rate
an inhibitor that reduces the Vmax of an enzyme by binding at the active site is a..... ANS direct non-
competitive inhibitor
cells raise metabolism without increasing ATP usage by... ANS opening proton channels in
mitochondria (channel is called an uncoupler protein)
what is the effect of metabolic thermogenesis (aka activity of the uncoupler protein) on the activity of
phosphofructokinase (PFK)? ANS increases PFK activity
