Active Transport, Passive Transport

        Help!  

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  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
