Consider return of the Jedi. Darth Vader turns out to be a hero.
The protagonist is the hero or central character, the focus of the story and it's themes. So unless you define "antagonist" so broadly as to include all possible opposition such as bad luck, geography, and weather, stories are perfectly possible without one. Consider "To Build a Fire" or "Hatchet" as stories with a protagonist lacking a proper opponent. Conversely, if you consider "antagonist" to indeed include any and all difficulties, then the statement "A Protagonist requires an Antagonist" is a tautology and your answer is no.

All literature is about conflict between two forces, the protagonist (the hero, the good guy) and the antagonist or antagonists (the villains or bad guys). Sometimes the antagonist isn't a person: it can be fate, the universe, God, the Devil. The antagonist can even be the protagonist (in a story where the conflict is between man and himself). But whoever or whatever the antagonist is, he/it is there to cause a problem for the protagonist. This problem, and the solving of it, is the story. You wouldn't want to read a story where there is no conflict to resolve. It's boring. Who wants to read a story about a character just going about their daily life, waking up, going to work, coming home, watching TV, etc. That's not a story; that's just a written account of someone's existence. What makes a story interesting -- what makes a story a story, in fact -- is that early on in the story, the protagonist is presented with a problem, a conflict between himself and an opposing force, and he spends the rest of the story trying to solve it. In essence, that is all a story is: setting up a conflict, and having your lead character or characters resolve it. Typically, the first half of the story is about setting up the conflict between the two people or forces (the protagonist and antagonist), and the second half of the story is about resolving that conflict. That's what conflict resolution is: how the author, through the characters, solves the problem and ends the conflict.
An antagonist is there to cause conflict, friction between the key characters. A good antagonist is a character in the story that the reader begins to dislike or even hate. Without an antagonist the story may as well be written as a he did this and I did this kind of story.
The characters typically solve the problem during the climax of the story when tensions are at their peak. Conflict resolution occurs after the climax and is where loose ends are tied up and a sense of closure is provided to the story.
it is the end of the story and what happens and what happened and how did they solve the problem.
