KHP 420G EXAM 1 QUESTIONS AND ANSWERS / LATEST UPDATE 2026/2027 |
100% CORRECT | GRADED A+
What is homeostasis? - ANSWER the maintenance of a relatively constant
internal environment.
What is the steady state? - ANSWER maintaining a stable internal
environment
What type of feedback system operates for glucose homeostasis? - ANSWER
Negative Feedback
What is acclimation? - ANSWER adaptation to environmental conditions
What type of proteins are induced by heat stress? - ANSWER heat shock
proteins
What is the difference between homeostasis and a steady state? ANSWER
Homeostasis is maintaining a constant environment, and while a steady state
refers to a stable environment maintained like heart rate, body temperature,
blood pressure.
Name some physiological variables that maintain a steady state during exercise
at a low-moderate (constant) intensity? - ANSWER heart rate, ventilation rate,
body temperature, oxygen consumption, blood pressure, hormones, blood
glucose concentration
, Explain the 3 general components of a biological control system. - ANSWER
receptor
control center
effector
Explain what negative feedback means. Give an example of a negative feedback
loop in the body (you may want to do a google search to find additional
examples). - ANSWER In negative feedback, the response will reverse or
cause the opposite effect of the original stimulus
What is a substrate? - ANSWER Any substance acted upon by an enzyme (to
produce ATP)
Name 6 characteristics of enzymes. - ANSWER Proteins
catalyze reaction
not changed in the reaction
highly specific
denatured by heat
denatured by acidity
Name 3 substrates we use fuel for - ANSWER Carbohydrates
Fats
Protein
Bioenergetics - ANSWER the study of the flow of energy from one form to
another
