BIOD 121 MODULE 2 EXAM SUMMER 2026
EXAMINATION TEST QUESTIONS AND
CORRECT ANSWERS FULL REVIEW
◉ have chloroplasts and mitochondria. Answer: Plant cells ________.
do not need chloroplasts because their mitochondria meet their
energy needs
use carbon dioxide but do not use oxygen
have chloroplasts and mitochondria
do not need mitochondria because their chloroplasts meet their
energy needs
◉ the sun. Answer: The ultimate source of the energy in food is
________.
consumers
the sun
producers
ATP
,◉ ATP. Answer: What compound directly provides energy for
cellular work?
What compound directly provides energy for cellular work?
C6H12O6
ATP
glucose
fat
◉ carbon dioxide and bring in more oxygen to support aerobic
metabolism. Answer: An abundant and continual supply of ATP is
necessary for all living cells. Active muscle cells require an
extraordinary amount of ATP to permit strenuous exercise for
prolonged periods. Toxins, reduced blood flow, and a compromised
respiratory system can interfere with the transport of oxygen to
active cells. A runner in a marathon faces multiple obstacles to
continue to produce sufficient ATP to remain competitive.
Breathing faster when we exercise is necessary to expel ________.
carbondioxide and bring in more oxygen to support aerobic
metabolism
oxygen and bring in more carbon dioxide to support aerobic
metabolism
,oxygen and bring in more carbon dioxide to support anaerobic
metabolism
carbon dioxide and bring in more oxygen to support anaerobic
metabolism
◉ insufficient oxygen is reaching the muscles. Answer: Lactic acid
build up in muscles is a sign that ________.
respiration is operating effectively
insufficient oxygen is reaching the muscles
aerobic respiration capacity has not been reached
the muscles will be able to operate continuously for a long time
◉ oxygen. Answer: A process is referred to as aerobic if it requires
________.
ATP
carbohydrates
carbon dioxide
oxygen
◉ heterotrophs and consumers. Answer: Humans are both ________.
, heterotrophs and consumers
autotrophs and producers
heterotrophs and producers
producers and decomposers
◉ use substances in the air as a major source of carbon. Answer:
Photosynthetic organisms like grass are able to ________.
convert light energy to chemical energy in mitochondria
make all of their organic matter from organic molecules in the soil.
use water they take in through their leaves as a final electron
acceptor.
use substances in the air as a major source of carbon
◉ store chemical energy, and they use cellular respiration to harvest
energy.. Answer: Plants use photosynthesis to________
change light energy into sugars.
harvest energy, and they use cellular respiration to store chemical
energy.
store chemical energy, and they use cellular respiration to harvest
energy.
