BIO final exam ||With Complete Verified Solutions
hypothesis
an educated guess
control
the standard that is used for comparison
independent variable
what you plan to change
dependent variable
changes as a result of the independent variable
constants
remain the same
isotope
has the same number of protons but a different number of neutrons
isomer
compounds with the same molecular formula but different structures
polysaccharide
carbohydrate
surface area to volume ratio
ratio of a cell's outside area to its internal volume.
hydrophilic
water loving, polar
hydrophobic
water hating, nonpolar
polarity
whether or not the electrons in a covalent molecule are shared evenly or symmetrically among the
atoms
aqueous
dissolved in water
activation energy
, the energy required for a reaction to occur
metabolic pathway
a series of chemical reactions that either builds a complex molecule or breaks down a complex molecule
into simpler compounds
feedback inhibition
process in which the product or result stops or limits the process
competitive inhibition
something other than the substrate competes with the substrate for the active site of the enzyme
passive transport
doesn't require ATP
active transport
requires ATP
receptor mediated transport
uses membrane receptors for specific solutes
phagocytosis
a cell engulfs large particles or whole cells by wrapping cell membrane around it and forming a vacuole
osmosis
diffusion of water across a semi-permeable membrane
diffusion
movement from high to low concentration
pinocytosis
cell engulfs liquid or small particles
exocytosis
used to export bulky molecules like polysaccharides or large proteins
phosphorylation
adding a phosphate to ADP
reduction
gain of electrons
oxidation
