I have to draw the complementary nucleotide to guanosine 5'-monophosphate and show the correct hydrogen bond base pair relations by using a dotted line. Then I have to circle the nucleoside portions of each nucleotide.
Next the next thing I need to learn is: How is the folding of a protein into its 3D shape after synthesis similar to the assembly of a membrane in a cell? Explain why proteins can vary tremendously in structure, while the basic plan of all membranes stays the same.
Last thing: "For enzyme-catalyzed reactions with a fixed amount of enzyme, at very low concentrations of substrate an increase in the substrate concentration leads to a corresponding increase in the reaction rate. Given a fixed amount of enzyme in the reaction, will the same realtion hold true for all concentrations of substrate? Explain, making explicit reference to an appropriate graph of substrate concentration versus reaction rate for the condition described above."
Help Please!!!! Even if you only know a little, anything helps.

For the first one, search with the terms Guanine Cytosine bond image.
You will find a number of images. Nucleosides are the portion of the nucleotide that do not contain the phosphate group.
For protein folding, try reading here. Protein folding is complex.

The substrate is what interacts with the enzyme to become changed. The enzyme (which is a protein) has a particular place on it for the substrate to interact with. As you increase the amount of substrate, more and more substrate will be processed in the same amount of time, BUT eventually you will reach a point where there aren't enough enzyme sites for the substrate, and the amount of substrate being converted in a specific amount of time will level off.
