Which of the following is the distinguishing characteristic between aldehydes and ketones? a. Ketones contain an oxygen atom, while aldehydes do not. b. Aldehydes are more substituted versions of ketones. c. Aldehydes contain an oxygen atom bound directly to a hydrogen atom, while the oxygen atoms in ketones are only bound to carbon atoms. d. Ketones contain a carbonyl group between two carbons, while the carbonyl group in an aldehyde must be attached to a hydrogen.

Microbiology In the competitive inhibition of enzyme activity, which statement is correct? Inhibitor directly competes with the substrate. Less substrates must be added in order to reach Vmax. The number of active sites is unlimited. None of the above. In the noncompetitive inhibition of enzyme activity, which statement is correct?Inhibitors will cause a conformational change in the enzyme, more substrate must be added to reach Vmax, Enzymes bound to the inhibitor can still bind substrate, none of the above. ....
