The glucose threshold

Flashcards covering key concepts related to kidney function, glucose absorption, and the effects of diabetes.

What role does the proximal convoluted tubule play in glucose absorption?

The proximal convoluted tubule normally absorbs glucose in the glomerular filtrate.

What happens to glucose when its concentration in the filtrate is too high?

If the concentration of glucose in the filtrate is too high, glucose will not be completely reabsorbed and can pass into the urine.

What can cause an increase in glucose levels in the filtrate?

Little or no insulin, as seen in type 1 diabetes.

How does insulin affect liver response?

Insulin facilitates the receptors in our membranes that help regulate glucose levels.

What condition can lead to damaged membrane receptors affecting glucose absorption?

Type 2 diabetes or gestational diabetes.

What is the relationship between glucose and water reabsorption?

The reabsorption of glucose can influence the reabsorption of water in the kidneys.
