Mitochondria - ANSWER Rod shaped bodies with a double membrane wall.Inner membrane is
thrown into folds, or cristae.Contain enzymes that oxidize foodstuffs to produce cellular
energy (ATP).Referred as the "powerhouses of cell".
Centrioles - ANSWER Paired, cylindrical bodies lie at right angles to each other.Direct
the formation of the mitotic spindle during division.Form the bases of cilia and flagella.
Cytoskeletal elements - ANSWER Microfilaments,termediate
filaments,Mircotubles,Provide cellular support,and Function in intracellular transport.
Microfiliaments - ANSWER Formed largely of actin.A contractile protein.Important in
cell mobility (particularly in muscle cells).
Intermediate filaments - ANSWER Stable elements composed of a variety of
proteins.Resit mechanical forces acting on cells.
Microtubles - ANSWER Form the internal structure of the centrioles.Help determine cell shape.
The nuclear envelope - ANSWER A highly regulated membrane barrier that separates the
nucleus from the cytoplasm in eukaryotic cells.
Nucleoli - ANSWER A small, typically round granular body composed of protein and RNA in the
nucleus of a cell. usually associated with a specific chromosomal site and involved in ribosomal
RNA synthesis and the formation of ribosomes.
Chromatin - ANSWER Mass of genetic material composed of DNA and proteins that condense
to form chromosomes during eukaryotic cell division.
, The cell life cycle - ANSWER The series of events that take place in a cell leading to its
division and duplication (replication) that produces two daughter cells.
Interphase - ANSWER The phase in which a cell takes in it's nutrients before entering
cell division.
Protein synthesis - ANSWER The process by which amino acids are linearly arranged into
proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and
various enzymes.
Monohybrid crosses - ANSWER A mating between individuals who have different alleles at
one genetic locus of interest.
Dihybrid crosses - ANSWER A cross between F1 offspring (first-generation offspring) of two
individuals that differ in two traits of particular interest.
Geneotype - ANSWER The "internally coded, inheritable information" carried by all living
organisms.
Phenotype - ANSWER The "outward, physical manifestation" of the organism.
Glycolysis - ANSWER The metabolic pathway that converts glucose C6H12O6, into pyruvate,
CH3COCOO− + H+.
Transition stage - ANSWER Takes place in the mitochondria.The pyruvate is combined
with NAD+ to form NADH and acetyl coenzyme A molecules.
Kreb cycle - ANSWER Also known as the citric acid cycle.The hydrogen atoms are removed
from the acetyl coenzyme A molecules to use the electrons to create ATP.
