DETAILED STUDY GUIDE
Symporter region - CORRECT ANSWER -Proteins that move two molecules
in the same direction across the membrane.
ATPase - CORRECT ANSWER -enzyme that catalyzes hydrolysis of ATP
Primary active transport - CORRECT ANSWER --Requires carrier proteins.
-Requires energy in the form of ATP
-This process enables polar or charged molecules to pass through a cell
membrane.
Secondary active transport - CORRECT ANSWER --This process requires that
some molecules move from an area of high concentration to an area of low
concentration.
-This process requires either carrier proteins or channel proteins.
Should have been checked.
,-This process requires energy in the form of an electrochemical gradient.
Correct answer.Should have been checked.
-This process enables polar or charged molecules to pass through a cell
membrane.
The difference between primary active transport and secondary active
transport - CORRECT ANSWER -Primary active transport requires ATP, but
secondary active transport requires an electrochemical gradient.
5 components of the cellular communication system - CORRECT ANSWER --
source cell
-receptor
-target cell
-non-target cell
-signaling molecule
Hormones: - CORRECT ANSWER --Hormones are signaling molecules.
Correct answer.Should have been checked.
-Hormones travel to target cells through the bloodstream.
Should have been checked.
-Hormones trigger a response in a target cell.
Correct answer.Should have been checked.
-Hormones can affect the function of any cell with the appropriate
receptors.
, Hydrophilic signaling molecules: - CORRECT ANSWER --have polar or
charged regions
-are unlikely to diffuse through the phospholipid bilayer of a cell membrane
phosphorylation - CORRECT ANSWER -the addition of a phosphate group to
a molecule
kinase - CORRECT ANSWER -An enzyme that transfers phosphate ions from
one molecule to another
dephosphorylation - CORRECT ANSWER -removal of a phosphate group
from a molecule
gene expression - CORRECT ANSWER -process by which a gene produces its
product and the product carries out its function
a receptor - CORRECT ANSWER --binds specific molecules
-can bee found on the exterior or interior of a cell
phosphatase - CORRECT ANSWER -an enzyme that removes a phosphate
group from a molecule
which type of cellular response will require the most time to occur -
CORRECT ANSWER -producing new proteins
