1. What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? Starling’s Law describes how fluids move across the capillary membrane. There are two major opposing forces that act to balance each other, hydrostatic pressure (pushing water out of the capillaries) and osmotic pressure (including oncontic pressure, which pushes fluid into the capillaries). Both electrolytes and proteins (oncontic pressure) in the blood affect osmot...

IPAP Biochemistry Questions and Answers 100% Solved Describe mechanisms by which enzymes affect biochemical reactions. ️️Enzymes serve as catalyst for biochemical reactions. A catalyst is a substance that speeds up a chemical reaction without itself being changed. Enzyme truisms ️️Enzymes are extremely efficient in terms of the number of substrate molecules with which they react. Enzymes are subject to a great deal of cellular controls. Enzymes speed up chemical reactions b...
