advantages - more effective and therefore a higher chance of success. since a genome is usually produced prior to procedure, risks and allergic reactions can be reduced effectively. little to no side effects are noticed as a genome analysis is done before. often the problem can be solved from the root in gene therapy.
disadvantages - ethical issues as often people are not comfortable in genome analysis. can be too expensive as gene therapy requires advanced technology. in the case of using radioactive elements, it may lead to mutations that may be a bigger issue than the disease itself.
The answer is C. Glucose is broken down in glycolysis, yielding two ATP; after the Krebs cycle, NADH and FADH2 are formed, yielding NAD+ and FAD in ETS reactions.
Carbon, oxygen, & hydrogen may all be elements found in ethanol, but when separated, they have completely different chemical compounds. They are pure elements where as ethanol is a mixture.
