The pressure that results due to the difference in the concentration of water present between the plasma and the interstitial fluid is called as blood colloid osmoticpressure.
The pressure leads to pulling of water present in the interstitial fluid and it gets drawn back into the plasma of the capillaries.
The movement of fluids results due to osmosis due to which the water moves from higher concentration to lower concentration.
Due to the movement of water back into the capillary plasma the formation of filtrate is prevented.
Ribose because ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
