Feedback Frenzy
The process of keeping blood sugar stable is an example of this type of homeostasis control.
What is negative feedback?
The pancreas has two main functions. Name one.
What is producing digestive enzymes OR producing hormones?
This sugar is the body’s main source of quick energy.
What is glucose?
After eating, your blood sugar will do this.
What is rise?
This type of diabetes happens when the body doesn’t produce insulin.
What is Type I diabetes?
Unlike blood sugar regulation, this type of feedback makes a process stronger until it reaches an end point.
What is positive feedback?
Which specific cells in the pancreas produce insulin?
What are beta cells?
If glucose is not used right away, the body converts it into this for short-term storage.
What is glycogen?
After a balanced meal, insulin helps glucose enter these cells for energy.
What are muscle and fat cells?
This type of diabetes happens when body cells ignore insulin’s signal.
What is Type II diabetes?
Give one example of a body process that uses positive feedback.
What is childbirth contractions OR blood clotting?
Which specific cells in the pancreas produce glucagon?
What are alpha cells?
Name one organ where glycogen is stored.
What is liver OR muscle?
Eating carbohydrates causes insulin to rise. Which type of food causes the least insulin response?
What is fat (or fatty foods)?
Why would untreated Type I diabetes cause weight loss?
What is because cells can’t use glucose, so the body breaks down fat and muscle for energy?
Name two body systems that must communicate for feedback to work in blood sugar control.
What are the nervous system and endocrine system?
The pancreas helps with digestion by releasing these substances.
What are digestive enzymes (like amylase, lipase, protease)?
Which body cells are most dependent on glucose as their only fuel source?
What are brain cells (neurons)?
Why does protein cause a smaller insulin release compared to carbohydrates?
What is because it breaks down slower and provides fewer glucose molecules?
Long-term high blood sugar can damage these two body systems the most.
What are the circulatory and nervous systems?
Why is negative feedback important for survival?
What is it keeps the body in balance and prevents dangerous highs and lows?
Why is the pancreas considered both an endocrine and exocrine organ?
What is because it releases hormones into the blood (endocrine) and enzymes into the small intestine (exocrine)?
After glycogen stores are used up, the body breaks down this macronutrient for long-term energy.
What is fat (triglycerides)?
Explain the sequence: You eat a meal → insulin rises → cells take in glucose → blood sugar does what?
What is returns to normal (homeostasis)?
Explain why a person might feel dizzy or shaky if their blood sugar drops too low.
What is because the brain depends on glucose, and low levels reduce brain energy?
