'gehen' and 'gehend' both have to do with movement on foot, but grammatically they do not play the same role. 'gehen' is a verb: it says what someone does. 'gehend' is an adjective or descriptive form: it describes a person or living being that is walking at that moment. Learners may confuse the words because they look similar. In normal everyday sentences, you usually need the verb 'gehen'. 'gehend' fits better when describing a state or posture, often in contrast to sitting or standing.
