Effects of Blood Glucose Level - Coggle Diagram
Effects of Blood Glucose Level
Purpose
Investigate how insulin and glucose affect blood glucose levels
Observe changes in fish behavior as an indicator of glucose levels
Understand how insulin maintains homeostasis
Background
Insulin Function
Insulin is produced by the pancreas
Released when blood glucose levels increase
Causes cells to take in glucose
Lowers blood glucose levels
Homeostasis
Insulin is the only hormone that decreases blood glucose
Maintains stable internal conditions
Blood Glucose States
Normoglycemia
Normal blood glucose
Fish swim normally
Hyperglycemia
High blood glucose
Fast, darting movement
Hypoglycemia
Low blood glucose
Slow, lethargic movement
Insulin Shock
Caused by excess insulin
Leads to hypoglycemia
Data
Insulin Trial
Before insulin
Behavior: Regular swimming
Blood glucose: Normoglycemic
15 seconds
Behavior: Regular swimming
Blood glucose: Normoglycemic
1 minute
Behavior: Lethargic, droopy dorsal fin
Blood glucose: Hypoglycemic
Glucose Trial
15 seconds
Behavior: Lethargic
Blood glucose: Hypoglycemic
1 minute
Behavior: Regular swimming
Blood glucose: Normoglycemic
Analysis
Insulin Effects
Insulin lowers blood glucose over tim
Fish became lethargic, indicating hypoglycemia
Confirms insulin causes glucose uptake by cells
Glucose Effects
Adding glucose restores normal levels
Fish returned to normal swimming behavior
Conclusion
Insulin is essential for regulating glucose levels
Blood glucose levels directly affect behavior
Reflection
Hardest connection
Linking fish behavior to internal blood glucose changes.
If repeated
I would measure glucose levels more frequently over time
I would add a graph showing behavior vs time
