When you sweat it burns fat. If you exercise hard enough you sweat.... burning calories.
your muscles burn when you exert yourself because when you lift heavy or lift for an excess ammount of reps you get a build up of lactic acid in your muscles
Your muscles burn them and without sufficient protein they will atrophy-in other words your body will start to burn exisitng protein in your muscles.
When you build enough muscles, your muscles will automatically burn more fat. However, doing both at the same time can seem daunting. If you want to see weight loss, you won't see any when you are gaining muscles. Once you have the muscles you want, you must maintain it. It will then burn fat, and your body won't lose any muscles.
During exercise, the muscles that burn the most fat are typically the larger muscles in the body, such as the quadriceps, hamstrings, and glutes. These muscles require more energy and oxygen, leading to increased fat burning during physical activity.

The harder you work the more ogygen is required.
Yes - if you do not have enough fat stores to burn then you will burn muscle - like with anorexic people whose muscles atrophy.
