In heme synthesis in mammalian cells: 1. uroporphyrin III is the immediate precursor of coproporhyrin III. 2. delta-aminolevulinic acid is formed by the condensation of succinyl CoA and valine. 3. ferric iron is inserted into protoporphyrin IX prior to attachment to the globin molecule.
If the linear function f is given, the linear equation of the graph of this function is obtained by defining the variable y to be the functional value f(x), that is, setting y = f(x) = ax + b and suppressing the functional notation in the middle.
Simple Definition of Linear Equation: An equation that forms a straight line on a graph. More precisely, a linear equation is one that is dependent only on constants and a variable raised to the first power. For example, \(y=6x+2\) is linear because it has no squares, cubes, square roots, sines, etc. Linear equations can always be manipulated to take this form:
