EXERCISE PHYSIOLOGY TEST 1 | QUESTIONS AND
ANSWERS | 2026 UPDATE WITH COMPLETE SOLUTION
During 60 minutes of submaximal exercise, the body temperature levels off
after 35-45 minutes, this is an example of Answer - Steady State
Changes in arterial blood across time while maintaining a constant mean
pressure during resting conditions is an example of Answer - Homeostasis
The overall goal of a control system is to regulate a physiological variable
Answer - At or near a constant value
Specialized tissue sensitive to changes in arterial blood pressure would serve as
an _______ in a biological control system. Answer - Sensor
The control center in the maintenance of body temperature is Answer - The
Hypothalamus
Increasing the original stimulus that triggered the control system is termed
Answer - Positive Feedback
A control system with a large gain is ________ capable of maintaining
homeostasis than a control system with a low gain. Answer - More
, The correction of disturbance and removal of stimulus is carried out by Answer
- The Effector
Which of the following can repair damaged cellular proteins? Answer - Stress
Proteins
The assessment of the response needed to correct a disturbance is made by
Answer - The Integration Center
Which of the following challenges to homeostasis would be expected during
exercise? Answer - Higher amounts of CO2 in cells
During heavy exercise or exercise in a hot or humid environment, you may have
Answer - Disturbance in the internal environment, disruption of steady state,
rapid responses of control systems
Severe disturbances in homeostasis result in fatigue and ultimately Answer - a
cessation of exercise
In order to continue to contract, muscle cells require Answer - ATP
The synthesis of molecules is called Answer - Anabolism
Protein synthesis within the cell is regulated by Answer - Genes
The speed of chemical reactions that occur within the body is regulated by
Answer - Temperature, pH, and enzymes
