Answer:
A, B and D are correct
Explanation:
Adenosine diphosphate (ADP) can form a bond with a phosphate group to form Adenosine triphosphate (ATP), which is the most abundant energy carrier molecule in cells. An endergonic reaction is a chemical reaction where there is a net input of energy, while an exergonic reaction generates energy. ATP hydrolysis releases energy (conversely to ATP synthesis that requires an input of free energy), and therefore ATP hydrolysis is an exergonic reaction. ATP hydrolysis releases around 7.3 kilocalories per mole. In a coupled reaction, the energy released by ATP hydrolysis is used by the cell to carry out endergonic reactions in an exergonic manner (e.g., glucose phosphorylation, which is an energetically unfavorable reaction).
Answer:
virus are obligate parasites. Viruses do not, however, carry out metabolic processes. Most notably, viruses differ from living organisms in that they cannot generate ATP.
Answer:
Introduce a mutation into the gene
Explanation:
In order to understand what is the purpose of the gene (protein) is there are a couple of options that can be take to identify it;s purpose.
One way to do this is to introduce a mutation into the wild type gene clone by site directed mutagenesis or by gene disruption. After the cloned gene is altered it can be re-introduced back into the wild-type yeast. The yeast is then allowed to multiply and the effect that the mutation has on the yeas can be observed.
