HOMEOSTASIS Test Questions with
Verified Answers
What is homeostasis - Ans -The process by which organisms maintain a relatively
stable internal environment.
What does homeostasis involve - Ans -control systems that keep your internal
environment roughly constant with certain limits
Why is it vital to keep your internal evironment constant - Ans -to keep cells
functioning normally and to prevent damage
What are the three key things that are important to maintain - Ans -temperature ph
and glucose
Why is it important to maintain body temp - Ans -if temp becomes to high enzymes
become dennatured. Enzymes molecules vibrate too much and the H bonds that hold their
3D shape break changing the shape of the active site so enzyme can no longer work as a
catalyst. Therefore metabollic reactions are less efficient.
Why is it important to maintain blood PH - Ans -if blood ph is too high or low enzymes
become dennatured.
The H bonds are effected and the 3D shape is changed changing the shape of the active
site meaning the enzyme no longer works as a catalyst. Therefore metabollic reactions are
less efficient.
What is the optimum PH - Ans -usually 7 but in the stomach its lower
