Data or Dat-uh?
In the dopamine experiment, what happened to reaction time as dopamine levels increased?
Reaction time decreased/got faster
Which system responds faster: nervous or endocrine?
Nervous system
What structure carries air from the throat toward the lungs?
Trachea
What hormone increases red blood cell production in some athletes?
EPO
Which biomolecule stores long-term energy?
Lipids
Compare the reaction times at 20 units and 80 units of dopamine.
20 units = 320 ms; 80 units = 210 ms; higher dopamine caused faster reactions
What neurotransmitter was directly connected to reaction time in the study guide?
Dopamine
What happens to oxygen after reaching the alveoli?
Diffuses into the blood/capillaries
Name ONE possible benefit of synthetic hormones in sports.
Increased endurance, muscle growth, recovery, etc.
What organelle contains DNA and controls the cell?
Nucleus
Explain why neurotransmitters can affect reaction time.
Required key points:
Explain ONE major difference between hormones and neurotransmitters.
Required key points:
Explain why alveoli need a large surface area.
Required key points:
Name ONE ethical concern related to synthetic hormone use in sports.
Unfair advantage/cheating/health risks
Explain why the circulatory system is important for cellular respiration.
Required key points:
Identify ONE limitation of the dopamine experiment and explain why it matters.
Required key points:
Possible answers:
Must explain how it affects reliability/validity.
A student drinks three energy drinks before an exam. Predict TWO physiological responses involving the nervous or endocrine system.
Required key points:
Possible answers:
A person damages their alveoli from vaping. Explain TWO consequences for the body.
Required key points:
Possible answers:
Explain ONE long-term physiological risk of using synthetic hormones.
Required key points:
Possible answers:
A student is breathing normally, but cells are not producing enough ATP. Identify TWO possible causes.
Required key points:
Possible answers:
Suggest ONE improvement to increase reliability AND explain scientifically why it would improve the experiment.
Required key points:
Possible answers:
Must connect improvement to reliability/validity.
Explain how nicotine can rapidly affect the body, even though hormones are usually slower chemical messengers.
Required key points:
A student says, “lungs create oxygen for the body.” Explain scientifically why this statement is incorrect.
Required key points:
Evaluate whether performance-enhancing hormones should be banned in sports using BOTH physiology and ethics.
Required key points:
Explain how the respiratory, circulatory, and cellular systems work together during exercise.
