Question
Answer
What molecule are transported via Active transport during Tubular Reabsorption?   1. Glucose; 2. Amino Acids; 3. Na+, K+, Ca++, HCO3-; 4. Water-Soluble Vitamins  
What factor regulates the speed of Active Transport?   Tm = Transport Maximum = carrier saturation  
What is the result of overwhelmed carriers during Tubular Reabsortion?   Glucose and Protein in Urine  
What 2 factors can affec Active Transport?   Hormones and some Drugs  
What are the 2 methods of Passive   Osmosis, Simple Diffusion  
What stimulates Osmosis during Tubular Reabsorption?   ^ concentration --> decrease concentration  
What factor influences Osmosis?   Tubular Permeability, Concentration Gradients  
At what point during Tubular Reabsorption is Water transported?   H2O follows Active Solute Reabsorption  
What molecules are transported via Simple Diffusion?   Urea, other NON-Polar Solutes follow water reabsorption  
What factor may interfere with H2O reabsorption?   anything that interferes with Solute Reabsorption interferes w/ H2O reabsorption  
Why does Simpl Diffusion occur?   when H2O leaves, Urea and NON-Polar solutes ^ in concentration --> Passive Diffusion --> reabsorption
