NAD+ has negligible absorbable at 340nm. Using a name example, explain how you could use the change in absorbable properties between NADH (molar absorbable 6220M/cm) and NAD+ to measure the rate of a biochemical reaction.
Biological membranes are highly complex structures despite the mosaic of it's constituents. Explain how these chemically and physically diverse elements can form a coherent dynamic structure
100 g of meat with the given composition is consumed: 1 % glycogen; 2 % fat (76 % C - 12 % O - 12 % H); 19% protein (16 % N - 52 % C - 28 % O - 4 % H); 2% ash. Assume a complete digestion and 50 % more osmoles to be secreted than needed for ureum. Formulate the water balance for a complete metabolic combustion of the meat
