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.
Analyzing Linear and Exponential Functions. Linear. To graph a linear function, such as f(x)=2x+3, you first look at the y-intercept (3). Next, you see the slope (2x) and graph that.The line will be sloping upwards because the slope is positive, and will meet the y axis at 3, since that is the y intercept.It will look like this:Exponential. To graph an exponential function, such as f(x)=2^x, you plug in the x values and plot the points.he line will be sloping upwards because the slope is positive, and will meet the y axis at 3, since that is the y intercept.
