Question 1(multiple choice worth 2 points)
where does the krebs cycle occur?
cytoplasm
mitochondrion
cell membrane
nucleus
question 2(multiple choice worth 2 points)
what stage of cellular respiration produces the most atp?
electron transport chain
glycolysis
krebs cycle
fermentation
question 3(multiple choice worth 2 points)
cellular respiration and fermentation
begin with the breakdown of glucose in glycolysis
produce the same number of atp molecules
only occur in animal cells
require oxygen molecules as a reactant
question 4(multiple choice worth 2 points)
during the process of cellular respiration, energy stored in glucose molecules is used to form
oxygen molecules
nad+
atp
carbohydrates
question 5(multiple choice worth 2 points)
when pyruvate molecules enter the mitochondrion during cellular respiration, they react to form
ethyl alcohol and atp
acetyl-coa and carbon dioxide
glucose and carbon dioxide
lactic acid and nad+
question 6(multiple choice worth 2 points)
during fermentation, the conversion of pyruvate into lactic acid requires
nadh
carbon dioxide
atp
oxygen gas
question 7(multiple choice worth 2 points)
alcoholic
forms fewer atp molecules than cellular respiration
uses oxygen and atp molecules as reactants
occurs in the muscle cells of animals and humans
gives off carbon dioxide and nadh as products
question 8(multiple choice worth 2 points)
which of the following is a necessary reactant for cellular respiration to occur?
carbon dioxide
nitrogen
oxygen
water
question 9(multiple choice worth 2 points)
what stage of cellular respiration is anaerobic?
glycolysis
calvin cycle
electron transport chain
krebs cycle
question 10(multiple choice worth 2 points)
what is produced during the krebs cycle?
co2, atp, nadh, and fadh2
pyruvate, co2, and atp
atp, fadh2, and h2o
h2o, adp, and nadh

Choose one animal (cheetas) and research on the internet what has contributed to this animal becoming "endangered" or "threatened." what animal you have chosen? how long has the animal been endangered or threatened? what has contributed to this animal’s endangered or threatened status? why is it important to save this animal from extinction? after researching and gathering facts, write a 350-word letter from the point of view of an animal rights' activist. be sure to include at least five facts that you learned from your research.
