Biology 189 Csn Exam 4 Questions With Complete Solutions
alcoholic fermentation Correct Answers Used pyruvate
decarboxylase to release CO2 and alcohol dehydrogenase to
oxidize NADH back to NAD+ so glycolysis can continue
Apoptosis Correct Answers programmed cell death
autocrine signaling Correct Answers cells respond to signaling
substances that they themselves secrete
capases Correct Answers main proteases that carry out
apoptosis
Chromosomes Correct Answers a threadlike structure of nucleic
acids and protein found in the nucleus of most living cells,
carrying genetic information in the form of genes.
crossing over Correct Answers exchange of genetic material
between homologous chromosomes during prophase I of
meiosis
diploid cell Correct Answers A cell containing two sets of
chromosomes (2n), one set inherited from each parent.
duplicated chromosome Correct Answers Daughter
chromosomes, exactly the same
Electrón carriers Correct Answers Oxidized for NAD+
Reduced form NADH
, formula for cellular respiration Correct Answers C6H12O6 + 6
O2 -> 6CO2 + 6H20 + ENERGY (ATP)
free energy Correct Answers energy that is available to do work
germ cells Correct Answers Reproductive cells that give rise to
sperm and ovum
haploid cell Correct Answers A cell containing only one set of
chromosomes (n).
hormone/endocrine signaling Correct Answers Long distance
signaling. Signals sent into blood stream, message may reach all
body cells.
How does bacterial conjunction occur? Correct Answers Two
prokaryotes connect together through a bridge called sex pilus or
conjugation bridge
How many Acetyl CoA enter into the Krebs cycle at once?
Correct Answers One at a time
How much of cell cycle is spent in mitosis? Correct Answers
10%
How much of the cell cycle is spent in interphase? Correct
Answers 90%
kinetochore Correct Answers A specialized region on the
centromere that links each sister chromatid to the mitotic
spindle.
