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 |
