[問題] solute potential
【問題】：有關solute potential跟water&pressure potential的關係
【問題起因】：
１．教科書：water potential=solute potential+pressure potential
water potential is a measure of the tendency of water molecule
to leave the solution
請問這裡的是指water molecule從solution到cell的tendency嗎?
那正常的water potential的數值會是多少呢?是否要以solution
和cell兩者的water potential的高低決定水的移動
２．solute potenial is a measure of change in water potential due
to addition of water
那water potential↑的話,solute potential是否也會↑呢?
３．以下是關於proximal convoluted tubule的solute potential的問題
教科書：Glucose,amino acids and ions diffuse into the cells of the
proximal convoluted tubule. They are then actively transpoted into
the surrounding peritubular capillaries. This leads to a drop in the
solute potential of the plasma in the capillaries. Water is drawn
from the glomerular filtrate to the capillaries by osmosis.
上面的問題搞不清楚，這裡也不明白了＝ ＝
希望大家為我解答<(_ _)>謝謝！
