The nucleus _________, which is essential for function and survival of the cell.
A) is the site of protein synthesis
B) contains the genetic code
C) transforms cellular energy
D) initiates aerobic metabolism - ANSWER -B) contains the genetic code
Although energy is not made in mitochondria, they are known as the power plants of the cell
because they:
A) contain RNA for protein synthesis.
B) utilize glycolysis for oxidative energy.
C) extract energy from organic compounds.
D) store calcium bonds for muscle contractions. - ANSWER -C) extract energy from
organic compounds.
Although the basic structure of the cell plasma membrane is formed by a lipid bilayer, most of
the specific membrane functions are carried out by:
A) bound and transmembrane proteins.
B) complex, long carbohydrate chains.
, C) surface antigens and hormone receptors.
D) a gating system of selective ion channels. - ANSWER -A) bound and transmembrane
proteins.
To effectively relay signals, cell-to-cell communication utilizes chemical messenger systems
that:
A) displace surface receptor proteins.
B) accumulate within cell gap junctions.
C) bind to contractile microfilaments.
D) release secretions into extracellular fluid. - ANSWER -D) release secretions into
extracellular fluid.
Aerobic metabolism, also known as oxidative metabolism, provides energy by:
A) removing the phosphate bonds from ATP.
B) combining hydrogen and oxygen to form water.
C) activating pyruvate stored in the cytoplasm.
D) breaking down glucose to form lactic acid. - ANSWER -B) combining hydrogen and
oxygen to form water.
Exocytosis, the reverse of endocytosis, is important in _________ into the extracellular fluid.
A) Engulfing and ingesting fluid and proteins for transport
B) Killing, degrading, and dissolving harmful microorganisms
C) Removing cellular debris and releasing synthesized substances
D) Destruction of particles by lysosomal enzymes for secretion - ANSWER -C) Removing
cellular debris and releasing synthesized substances
The process responsible for generating and conducting membrane potentials is:
A) diffusion of current-carrying ions.
B) millivoltage of electrical potential.
