QUESTIONS WITH ANSWERS |\ |\




How do cells make energy? - CORRECT ANSWERS ✔✔Metabolism
|\ |\ |\ |\ |\ |\ |\ |\




two types of metabolism - CORRECT ANSWERS ✔✔aerobic and
|\ |\ |\ |\ |\ |\ |\ |\ |\


anaerobic metabolism |\




happens INSIDE of the mitochondria; requires oxygen - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔aerobic metabolism |\ |\




happens OUTSIDE of the mitochondria; also called glycolysis -
|\ |\ |\ |\ |\ |\ |\ |\ |\


CORRECT ANSWERS ✔✔anaerobic metabolism
|\ |\ |\




result of anaerobic metabolism - CORRECT ANSWERS ✔✔2 ATP
|\ |\ |\ |\ |\ |\ |\ |\




result of aerobic metabolism - CORRECT ANSWERS ✔✔34 ATP
|\ |\ |\ |\ |\ |\ |\ |\




What happens when there is energy failure? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔The sodium-potassium pump will not function at all
|\ |\ |\ |\ |\ |\ |\ |\




intracellular ion - CORRECT ANSWERS ✔✔Potassium
|\ |\ |\ |\ |\




extracellular ion - CORRECT ANSWERS ✔✔Sodium
|\ |\ |\ |\ |\

,1st Step of the Sodium Potassium Pump - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔The sodium-potassium pump binds three sodium ions and a
|\ |\ |\ |\ |\ |\ |\ |\ |\


molecule of ATP. |\ |\




2nd Step of the Sodium Potassium Pump - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔The spitting of ATP provides energy to change the shape of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the channel. The sodium ions are driven through the channel.
|\ |\ |\ |\ |\ |\ |\ |\ |\




3rd Step of the Sodium Potassium Pump - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔The sodium ions are released to the outside of the membrane,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


and the new shape of the channel allows two potassium ions to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


bind.


4th Step of the Sodium Potassium Pump - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔Release of the phosphate allows the channel to revert to its
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


original form, releasing the potassium ions on the inside of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


membrane.


decreased cell SIZE - CORRECT ANSWERS ✔✔Atrophy
|\ |\ |\ |\ |\ |\




increased cell SIZE - CORRECT ANSWERS ✔✔Hypertrophy
|\ |\ |\ |\ |\ |\




increased cell NUMBER - CORRECT ANSWERS ✔✔Hyperplasia
|\ |\ |\ |\ |\ |\




replacement of one cell type by another cell type - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔Metaplasia |\

, deranged cellular growth - CORRECT ANSWERS ✔✔Dysplasia
|\ |\ |\ |\ |\ |\




new growth (tumor) - CORRECT ANSWERS ✔✔Neoplasia
|\ |\ |\ |\ |\ |\




inherited disorder from a family member caused by DNA
|\ |\ |\ |\ |\ |\ |\ |\ |\


abnormality - CORRECT ANSWERS ✔✔Genetic Disorders |\ |\ |\ |\ |\




Most common types of Genetic Disorders - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔Down Syndrome, Cystic Fibrosis, Huntington's Disease
|\ |\ |\ |\ |\




two types of alleles in genes - CORRECT ANSWERS ✔✔Dominant
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


& Recessive
|\




produce a dominant phenotype
|\ |\ |\




this is what will be "seen" or "appear" - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔dominant


produce a recessive phenotype
|\ |\ |\




dominant will overpower these - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\


✔✔recessive


If recessive gene is "shown" then both parents
|\ |\ |\ |\ |\ |\ |\ |\


_____________________. - CORRECT ANSWERS ✔✔must be recessive |\ |\ |\ |\ |\ |\
