Question

Many solutes that must move into and out of cells exist in either a protonated or ionized form, or they have functional groups that can be either protonated or ionized. Simple molecules such as CO_2 H_3 PO_4 (phosphoric acid), and NH_3 (ammonia) are in this category, as are organic molecules with carboxylic acid groups, phosphate groups, and/or amino groups. Part G Instead of ammonia, consider the uptake of acetic acid. CH_3 COOH, an important intermediate in several biological pathways. What is the charged form in this case?

Explanation / Answer

Ammonia, NH3 is a neutral molecule does not possess a charge and during the process of uptake will accepts a proton to from NH4+. Now the system has a charge +1.

Acetic acid , CH3COOH, CH3COOH breaks down into CH3COO- and H+ in solution.

i.e. - The charge is -1.
