Flex your science skills on a new audiobook ZDLTK152021375071X
This unique audiobook project is designed to help highschool students with their biology studies. The voice we're looking for needs to sound believable as a science teacher. Be conversational and natural sounding, yes---but we also need to hear the technical terminology flow into the text as naturally as you perform the rest of it. Age-wise, we're not terribly picky, but, again, we do want to believe you in the role you're playing. A teenager wouldn't be appropriate for this. We look forward to hearing from you.

Sample script provided for auditions:
All enzymes are protein molecules, but they can also be assisted by non-proteins, known as cofactors. Organic cofactors are called coenzymes, and include many vitamins. Inorganic cofactors such as metal ions can also assist in catalyzing reactions.
In addition, the activity of enzymes can be affected by a number of environmental factors, such as temperature, pH, and even the concentration of an enzyme's substrate. The more substrate there is relative to the number of enzyme molecules, the faster the reaction will proceed. All enzymes have a narrow band of ideal conditions at which they operate---for most of the enzymes in our body, those conditions are 98.6 degrees Fahrenheit, and a pH of around 7. So, we lucked out, there.
There are some exceptions, of course. Pepsin, our primary digestive enzyme, is optimized for the low-pH environment of the human stomach, where high concentrations of hydrochloric acid drop the pH to an extremely acidic pH of 2. Pepsin is capable of functioning in a less acidic environment, but it won't be anywhere near as effective a catalyst as it would be at its optimal pH.
Finally, you should know a little bit about enzyme regulation. Cells rely on enzymes not just to lower activation energies, but also to give them more control and fine-tuning over when to start, stop, speed up or slow down reactions. Instead of trying to halt a reaction directly, many times a cell will instead regulate the enzymes which catalyze that reaction. The three types of enzyme regulation you should be aware of for the AP exam are allosteric [al-oh-STARE-ick] regulation, competitive inhibition and noncompetitive inhibition.
Please note that you should only use the script or your recording of it for auditioning purposes. The script is property, unless otherwise specified, of the voice seeker and it is protected by international copyright laws.
