Why does fat oxidation require more energy compared with glucose oxidation?

• because it's a simple molecular structure

• because it has more carbon bonds

• it does not require more energy

What is the crossover concept?

• When the body switches over to carbohydrate from fat as intensity increases

• When the body switches over to fat from carbohydrate as intensity increases

• When the body switches over to carbohydrate from protein as intensity increases
