Quiz 3, 4, 5
Which of the following terms best describes entropy?
disorder
Simple diffusion across a plasma membrane is called passive transport because it
does not require energy from the cell.
Both plants & animals need mitochondria to
produce ATP
A general eukaryotic cell is typically in the area of
10-100 micrometers.
Identify which of the following statements is not true.
ATP is comprised of a sugar, base, and two phosphate groups.
How does DNA differ from RNA?
DNA is comprised of a double strand, RNA is a single strand.
Where do the vesicles that are being made for secretion from the cell become modified and packaged?
Golgi apparatus
Which of the following is best associated with a coupled reaction?
The metabolic reaction requires energy from ATP.
Osmosis includes
both the diffusion of water and a semi-permeable membrane.
What function does the nucleolus have?
codes for the synthesis of ribosomal RNA
Chromosomes are
condensed chromatin.
Which one of the following is a function of proteins?
enzymatic activity
Metabolic pathways are known for all of the following EXCEPT
enzymes to help raise the energy of activation.
Molecules move from greater to lesser concentration through a transport protein in
facilitated diffusion.
A polypeptide forms a pleated sheet or a helix as its tertiary structure.
false
The principle role for sugars in living things is
for creating energy.
Humans store their polysaccharides in the form of
glycogen.
Compared with a eukaryotic cell, a prokaryotic cell
lacks organelles beyond ribosomes.
Kelly would like to observe the cilia on the surface of a live paramecium: a singular cell organism. The best device to do this would be a
light microscope.
Where within the cell is ATP built up?
mitochondria
Which of the following correctly lists the parts of a nucleotide of RNA?
nitrogen-containing base, ribose, phosphate
A white blood cell surrounds and engulfs a worn-out red blood cell, forming a vesicle around the red blood cell. This process is called
phagocytosis.
What must materials pass through to enter or leave a cell?
plasma membrane
Eukaryotic cells have DNA enclosed in a double membrane called the nucleus. The nucleus functions to
separate the DNA from other activities that occur in the cytoplasm.
Resolving power is
the ability to tell two points apart as separate points.
Eukaryotic cells move their organelles via
the cytoskeleton.
Which nitrogen containing base is found in DNA but not in RNA?
thymine
In sickle cell disease, malformation of red blood cells is caused by only one mistake for one amino acid in the genetic code for hemoglobin.
true
