Explanation / Answer

1 ..d) chemoheterotroph.

2... c) lowers

3.... f) can be used multiple times....if there are two options . is also mostly specific for a reaction

4....d) non-competitive inhibitor of a regulator molecule that binds at a site other than active site ... irreversibly inactivating the enzyme

According to chegg minimum protocol I have to answer first four question as a courtesy i am answering a few more ....

5.... vitamins and metals ... cofactors are metal ions and coenzymes are vitamins

8...a) produce some atp

9....d)produce a lot of nadh and fadh

10....b) produce a lot of atp ....
