2) No.
Fuel injected:
Most likely is the hesitation has another cause such as a bad TPS, MAF or MAP that has lead over time to oxygen sensor damage. With a bad oxygen sensor, your ECU has lost it's fuel learn parameters and made the hesitation problem worse.
Carbureted:
More likely is a minor leak inside the carburetor causing the hesitation and this may have also caused damage to the oxygen sensor. Rebuild the carburetor and replace the oxygen sensor at the same time.
Answer
yes and no... the purpose of the O2 sensor is to monitor the exhaust gasses to ensure that the exhaust is within tolerance of federal regulations (to make sure you're not polluting). On later model vehicles, the O2 sensor plays a part in controlling your fuel/air ratio, depending on what the O2 sensor sees, it can make the engine run rich, giving you more power in some cases, but trying to flood the engine when you floor the pedal. Which sounds like the problem in your case.
