roughly a cube of 15 μm on a side. Assume the density of cell is 1.03gm/ml and 20% of total weight of which is occupied
Mechanistically, enzyme catalysis and lipid structure involves substrate affinity, transition state stabilization and phospholipid composition govern function. This validates 8.3x10 ⁹ because it reflects catalytic efficiency and membrane organization, a pattern repeatedly demonstrated in biochemistry research.
Ref: Lehninger Principles of Biochemistry, Chapter 9, Lipids and Membranes, explains phospholipid components, glycerol, fatty acids, phosphate group and membrane structure providing foundation for lipid biochemistry.
